+Internal FIBITMAP allocation.
+
+This function accepts (ext_bits, ext_pitch) arguments. If these are provided the FIBITMAP
+will be allocated as "header only", but bits and pitch will be stored within the FREEIMAGEHEADER
+and the resulting FIBITMAP will have pixels, i.e. HasPixels() will return TRUE.
+- GetBits() and GetPitch return the correct values - either offsets or the stored values (user-provided bits and pitch).
+- Clone() creates a new FIBITMAP with copy of the user pixel data.
+- Unload's implementation does not need to change - it just release a "header only" dib.
+Note that when using external data, the data does not need to have the same alignment as the default 4-byte alignment.
+This enables the possibility to access buffers with, for instance, stricter alignment,
+like the ones used in low-level APIs like OpenCL or intrinsics.
+
+ at param header_only If TRUE, allocate a 'header only' FIBITMAP, otherwise allocate a full FIBITMAP
+ at param ext_bits Pointer to external user's pixel buffer if using wrapped buffer, NULL otherwise
+ at param ext_pitch Pointer to external user's pixel buffer pitch if using wrapped buffer, 0 otherwise

+ at param height Image height
+ at param bpp Number of bits per pixel

+ A dynamic view is a FreeImage bitmap with its own width and height, that,
+ however, shares its bits with another FreeImage bitmap. Typically, views
+ are used to define one or more rectangular sub-images of an existing
+ bitmap. All FreeImage operations, like saving, displaying and all the
+ toolkit functions, when applied to the view, only affect the view's
+ rectangular area.
+
+ Although the view's backing image's bits not need to be copied around,
+ which makes the view much faster than similar solutions using
+ FreeImage_Copy, a view uses some private memory that needs to be freed by
+ calling FreeImage_Unload on the view's handle to prevent memory leaks.
+
+ Only the backing image's pixels are shared by the view. For all other image
+ data, notably for the resolution, background color, color palette,
+ transparency table and for the ICC profile, the view gets a private copy
+ of the data. By default, the backing image's metadata is NOT copied to
+ the view.
+
+ As with all FreeImage functions that take a rectangle region, top and left
+ positions are included, whereas right and bottom positions are excluded
+ from the rectangle area.
+
+ Since the memory block shared by the backing image and the view must start
+ at a byte boundary, the value of parameter left must be a multiple of 8
+ for 1-bit images and a multiple of 2 for 4-bit images.
+
+ @param dib The FreeImage bitmap on which to create the view.
+ @param left The left position of the view's area.
+ @param top The top position of the view's area.
+ @param right The right position of the view's area.
+ @param bottom The bottom position of the view's area.
+ @return Returns a handle to the newly created view or NULL if the view
+ was not created.

+/**
+Returns the color type of a bitmap. In contrast to FreeImage_GetColorType,
+this function optionally supports a boolean OUT parameter, that receives TRUE,
+if the specified bitmap is greyscale, that is, it consists of grey colors only.
+Although it returns the same value as returned by FreeImage_GetColorType for all
+image types, this extended function primarily is intended for palletized images,
+since the boolean pointed to by 'bIsGreyscale' remains unchanged for RGB(A/F)

CHANGE LOG for Independent JPEG Group's JPEG software
+Version 9a 19-Jan-2014
+-----------------------
+
+Add support for wide gamut color spaces (JFIF version 2).
+Improve clarity and accuracy in color conversion modules.
+Note: Requires rebuild of test images.
+
+Extend the bit depth support to all values from 8 to 12
+(BITS_IN_JSAMPLE configuration option in jmorecfg.h).
+jpegtran now supports N bits sample data precision with all N from 8 to 12
+in a single instance. Thank to Roland Fassauer for inspiration.
+
+Try to resolve issues with new boolean type definition.
+Thank also to v4hn for suggestion.
+
+Enable option to use default Huffman tables for lossless compression
+(for hardware solution), and in this case improve lossless RGB compression
+with reversible color transform. Thank to Benny Alexandar for hint.
+
+Extend the entropy decoding structure, so that extraneous bytes between
+compressed scan data and following marker can be reported correctly.
+Thank to Nigel Tao for hint.
+
+Add jpegtran -wipe option and extension for -crop.
+Thank to Andrew Senior, David Clunie, and Josef Schmid for suggestion.
+
+
+Version 9 13-Jan-2013
+----------------------
+
+Add cjpeg -rgb1 option to create an RGB JPEG file, and insert
+a simple reversible color transform into the processing which
+significantly improves the compression.
+The recommended command for lossless coding of RGB images is now
+cjpeg -rgb1 -block 1 -arithmetic.
+As said, this option improves the compression significantly, but
+the files are not compatible with JPEG decoders prior to IJG v9
+due to the included color transform.
+The used color transform and marker signaling is compatible with
+other JPEG standards (e.g., JPEG-LS part 2).
+
+Remove the automatic de-ANSI-fication support (Automake 1.12).
+Thank also to Nitin A Kamble for suggestion.
+
+Add remark for jpeg_mem_dest() in jdatadst.c.
+Thank to Elie-Gregoire Khoury for the hint.
+
+Support files with invalid component identifiers (created
+by Adobe PDF). Thank to Robin Watts for the suggestion.
+
+Adapt full buffer case in jcmainct.c for use with scaled DCT.
+Thank to Sergii Biloshytskyi for the suggestion.
+
+Add type identifier for declaration of noreturn functions.
+Thank to Brett L. Moore for the suggestion.
+
+Correct argument type in format string, avoid compiler warnings.
+Thank to Vincent Torri for hint.
+
+Add missing #include directives in configuration checks, avoid
+configuration errors. Thank to John Spencer for the hint.

+ -------------------------------------------------------------------------------
+ Introduction
+
+ sal.h provides a set of annotations to describe how a function uses its
+ parameters - the assumptions it makes about them, and the guarantees it makes
+ upon finishing.
+
+ Annotations may be placed before either a function parameter's type or its return
+ type, and describe the function's behavior regarding the parameter or return value.
+ There are two classes of annotations: buffer annotations and advanced annotations.
+ Buffer annotations describe how functions use their pointer parameters, and
+ advanced annotations either describe complex/unusual buffer behavior, or provide
+ additional information about a parameter that is not otherwise expressible.
+
+ -------------------------------------------------------------------------------
+ Buffer Annotations
+
+ The most important annotations in sal.h provide a consistent way to annotate
+ buffer parameters or return values for a function. Each of these annotations describes
+ a single buffer (which could be a string, a fixed-length or variable-length array,
+ or just a pointer) that the function interacts with: where it is, how large it is,
+ how much is initialized, and what the function does with it.
+
+ The appropriate macro for a given buffer can be constructed using the table below.
+ Just pick the appropriate values from each category, and combine them together
+ with a leading underscore. Some combinations of values do not make sense as buffer
+ annotations. Only meaningful annotations can be added to your code; for a list of
+ these, see the buffer annotation definitions section.
+
+ Only a single buffer annotation should be used for each parameter.
+
+ |------------|------------|---------|--------|----------|----------|---------------|
+ | Level | Usage | Size | Output | NullTerm | Optional | Parameters |
+ |------------|------------|---------|--------|----------|----------|---------------|
+ | <> | <> | <> | <> | _z | <> | <> |
+ | _deref | _in | _ecount | _full | _nz | _opt | (size) |
+ | _deref_opt | _out | _bcount | _part | | | (size,length) |
+ | | _inout | | | | | |
+ | | | | | | | |
+ |------------|------------|---------|--------|----------|----------|---------------|
+
+ Level: Describes the buffer pointer's level of indirection from the parameter or
+ return value 'p'.
+
+ <> : p is the buffer pointer.
+ _deref : *p is the buffer pointer. p must not be NULL.
+ _deref_opt : *p may be the buffer pointer. p may be NULL, in which case the rest of
+ the annotation is ignored.
+
+ Usage: Describes how the function uses the buffer.
+
+ <> : The buffer is not accessed. If used on the return value or with _deref, the
+ function will provide the buffer, and it will be uninitialized at exit.
+ Otherwise, the caller must provide the buffer. This should only be used
+ for alloc and free functions.
+ _in : The function will only read from the buffer. The caller must provide the
+ buffer and initialize it. Cannot be used with _deref.
+ _out : The function will only write to the buffer. If used on the return value or
+ with _deref, the function will provide the buffer and initialize it.
+ Otherwise, the caller must provide the buffer, and the function will
+ initialize it.
+ _inout : The function may freely read from and write to the buffer. The caller must
+ provide the buffer and initialize it. If used with _deref, the buffer may
+ be reallocated by the function.
+
+ Size: Describes the total size of the buffer. This may be less than the space actually
+ allocated for the buffer, in which case it describes the accessible amount.
+
+ <> : No buffer size is given. If the type specifies the buffer size (such as
+ with LPSTR and LPWSTR), that amount is used. Otherwise, the buffer is one
+ element long. Must be used with _in, _out, or _inout.
+ _ecount : The buffer size is an explicit element count.
+ _bcount : The buffer size is an explicit byte count.
+
+ Output: Describes how much of the buffer will be initialized by the function. For
+ _inout buffers, this also describes how much is initialized at entry. Omit this
+ category for _in buffers; they must be fully initialized by the caller.
+
+ <> : The type specifies how much is initialized. For instance, a function initializing
+ an LPWSTR must NULL-terminate the string.
+ _full : The function initializes the entire buffer.
+ _part : The function initializes part of the buffer, and explicitly indicates how much.
+
+ NullTerm: States if the present of a '\0' marks the end of valid elements in the buffer.
+ _z : A '\0' indicated the end of the buffer
+ _nz : The buffer may not be null terminated and a '\0' does not indicate the end of the
+ buffer.
+ Optional: Describes if the buffer itself is optional.
+
+ <> : The pointer to the buffer must not be NULL.
+ _opt : The pointer to the buffer might be NULL. It will be checked before being dereferenced.
+
+ Parameters: Gives explicit counts for the size and length of the buffer.
+
+ <> : There is no explicit count. Use when neither _ecount nor _bcount is used.
+ (size) : Only the buffer's total size is given. Use with _ecount or _bcount but not _part.
+ (size,length) : The buffer's total size and initialized length are given. Use with _ecount_part
+ and _bcount_part.

+ Buffer Annotation Examples
+
+ LWSTDAPI_(BOOL) StrToIntExA(
+ LPCSTR pszString, -- No annotation required, const implies __in.
+ DWORD dwFlags,
+ __out int *piRet -- A pointer whose dereference will be filled in.
+ );
+
+ void MyPaintingFunction(
+ __in HWND hwndControl, -- An initialized read-only parameter.
+ __in_opt HDC hdcOptional, -- An initialized read-only parameter that might be NULL.
+ __inout IPropertyStore *ppsStore -- An initialized parameter that may be freely used
+ -- and modified.
+ );
+
+ LWSTDAPI_(BOOL) PathCompactPathExA(
+ __out_ecount(cchMax) LPSTR pszOut, -- A string buffer with cch elements that will
+ -- be NULL terminated on exit.
+ LPCSTR pszSrc, -- No annotation required, const implies __in.
+ UINT cchMax,
+ DWORD dwFlags
+ );
+
+ HRESULT SHLocalAllocBytes(
+ size_t cb,
+ __deref_bcount(cb) T **ppv -- A pointer whose dereference will be set to an
+ -- uninitialized buffer with cb bytes.
+ );
+
+ __inout_bcount_full(cb) : A buffer with cb elements that is fully initialized at
+ entry and exit, and may be written to by this function.
+
+ __out_ecount_part(count, *countOut) : A buffer with count elements that will be
+ partially initialized by this function. The function indicates how much it
+ initialized by setting *countOut.
+
+ -------------------------------------------------------------------------------
+ Advanced Annotations
+
+ Advanced annotations describe behavior that is not expressible with the regular
+ buffer macros. These may be used either to annotate buffer parameters that involve
+ complex or conditional behavior, or to enrich existing annotations with additional
+ information.
+
+ __success(expr) f :
+ <expr> indicates whether function f succeeded or not. If <expr> is true at exit,
+ all the function's guarantees (as given by other annotations) must hold. If <expr>
+ is false at exit, the caller should not expect any of the function's guarantees
+ to hold. If not used, the function must always satisfy its guarantees. Added
+ automatically to functions that indicate success in standard ways, such as by
+ returning an HRESULT.
+
+ __nullterminated p :
+ Pointer p is a buffer that may be read or written up to and including the first
+ NULL character or pointer. May be used on typedefs, which marks valid (properly
+ initialized) instances of that type as being NULL-terminated.
+
+ __nullnullterminated p :
+ Pointer p is a buffer that may be read or written up to and including the first
+ sequence of two NULL characters or pointers. May be used on typedefs, which marks
+ valid instances of that type as being double-NULL terminated.
+
+ __reserved v :
+ Value v must be 0/NULL, reserved for future use.
+
+ __checkReturn v :
+ Return value v must not be ignored by callers of this function.
+
+ __typefix(ctype) v :
+ Value v should be treated as an instance of ctype, rather than its declared type.
+
+ __override f :
+ Specify C#-style 'override' behaviour for overriding virtual methods.
+
+ __callback f :
+ Function f can be used as a function pointer.
+
+ __format_string p :
+ Pointer p is a string that contains % markers in the style of printf.
+
+ __blocksOn(resource) f :
+ Function f blocks on the resource 'resource'.
+
+ __fallthrough :
+ Annotates switch statement labels where fall-through is desired, to distinguish
+ from forgotten break statements.
+
+ -------------------------------------------------------------------------------
+ Advanced Annotation Examples
+
+ __success(return == TRUE) LWSTDAPI_(BOOL)
+ PathCanonicalizeA(__out_ecount(MAX_PATH) LPSTR pszBuf, LPCSTR pszPath) :
+ pszBuf is only guaranteed to be NULL-terminated when TRUE is returned.
+
+ typedef __nullterminated WCHAR* LPWSTR : Initialized LPWSTRs are NULL-terminated strings.
+
+ __out_ecount(cch) __typefix(LPWSTR) void *psz : psz is a buffer parameter which will be
+ a NULL-terminated WCHAR string at exit, and which initially contains cch WCHARs.

+/************************************************************************
+* Introduction
+*
+* specstrings.h provides a set of annotations to describe how a function uses
+* its parameters - the assumptions it makes about them, and the guarantees it
+* makes upon finishing.
+*
+* Annotations must be placed before a function parameter's type or its return
+* type. There are two basic classes of common annotations buffer annotations
+* and advanced annotations. Buffer annotations describe how functions use
+* their pointer parameters, and advanced annotations either describe
+* complex/unusual buffer behavior, or provide additional information about a
+* parameter that is not otherwise expressible.
+*
+* Buffer Annotations
+*
+* The most important annotations in SpecStrings.h provide a consistent way to
+* annotate buffer parameters or return values for a function. Each of these
+* annotations describes a single buffer (which could be a string, a
+* fixed-length or variable-length array, or just a pointer) that the function
+* interacts with: where it is, how large it is, how much is initialized, and
+* what the function does with it.
+*
+* The appropriate macro for a given buffer can be constructed using the table
+* below. Just pick the appropriate values from each category, and combine
+* them together with a leading underscore. Some combinations of values do not
+* make sense as buffer annotations. Only meaningful annotations can be added
+* to your code; for a list of these, see the buffer annotation definitions
+* section.
+*
+* Only a single buffer annotation should be used for each parameter.
+*
+* |------------|------------|---------|--------|----------|---------------|
+* | Level | Usage | Size | Output | Optional | Parameters |
+* |------------|------------|---------|--------|----------|---------------|
+* | <> | <> | <> | <> | <> | <> |
+* | _deref | _in | _ecount | _full | _opt | (size) |
+* | _deref_opt | _out | _bcount | _part | | (size,length) |
+* | | _inout | | | | |
+* | | | | | | |
+* |------------|------------|---------|--------|----------|---------------|
+*
+* Note: "<>" represents the empty string.
+*
+* Level: Describes the buffer pointer's level of indirection from the
+* parameter or return value 'p'.
+*
+* <> : p is the buffer pointer.
+* _deref : *p is the buffer pointer. p must not be NULL.
+* _deref_opt : *p may be the buffer pointer. p may be NULL, in which case the
+* rest of the annotation is ignored.
+*
+* Usage: Describes how the function uses the buffer.
+*
+* <> : The buffer is not accessed. If used on the return value or with
+* _deref, the function will provide the buffer, and it will be uninitialized
+* at exit. Otherwise, the caller must provide the buffer. This should only
+* be used for alloc and free functions.
+*
+* _in : The function will only read from the buffer. The caller must provide
+* the buffer and initialize it.
+*
+* _out : The function will only write to the buffer. If used on the return
+* value or with _deref, the function will provide the buffer and initialize
+* it. Otherwise, the caller must provide the buffer, and the function will
+* initialize it.
+*
+* _inout : The function may freely read from and write to the buffer. The
+* caller must provide the buffer and initialize it. If used with _deref, the
+* buffer may be reallocated by the function.
+*
+* Size: Describes the total size of the buffer. This may be less than the
+* space actually allocated for the buffer, in which case it describes the
+* accessible amount.
+*
+* <> : No buffer size is given. If the type specifies the buffer size (such
+* as with LPSTR and LPWSTR), that amount is used. Otherwise, the buffer is
+* one element long. Must be used with _in, _out, or _inout.
+*
+* _ecount : The buffer size is an explicit element count.
+*
+* _bcount : The buffer size is an explicit byte count.
+*
+* Output: Describes how much of the buffer will be initialized by the
+* function. For _inout buffers, this also describes how much is initialized
+* at entry. Omit this category for _in buffers; they must be fully
+* initialized by the caller.
+*
+* <> : The type specifies how much is initialized. For instance, a function
+* initializing an LPWSTR must NULL-terminate the string.
+*
+* _full : The function initializes the entire buffer.
+*
+* _part : The function initializes part of the buffer, and explicitly
+* indicates how much.
+*
+* Optional: Describes if the buffer itself is optional.
+*
+* <> : The pointer to the buffer must not be NULL.
+*
+* _opt : The pointer to the buffer might be NULL. It will be checked before
+* being dereferenced.
+*
+* Parameters: Gives explicit counts for the size and length of the buffer.
+*
+* <> : There is no explicit count. Use when neither _ecount nor _bcount is
+* used.
+*
+* (size) : Only the buffer's total size is given. Use with _ecount or _bcount
+* but not _part.
+*
+* (size,length) : The buffer's total size and initialized length are
+* given. Use with _ecount_part and _bcount_part.
+*
+* ----------------------------------------------------------------------------
+* Buffer Annotation Examples
+*
+* LWSTDAPI_(BOOL) StrToIntExA(
+* LPCSTR pszString, // No annotation required, const implies __in.
+* DWORD dwFlags,
+* __out int *piRet // A pointer whose dereference will be filled in.
+* );
+*
+* void MyPaintingFunction(
+* __in HWND hwndControl, // An initialized read-only parameter.
+* __in_opt HDC hdcOptional, // An initialized read-only parameter that
+* // might be NULL.
+* __inout IPropertyStore *ppsStore // An initialized parameter that
+* // may be freely used and modified.
+* );
+*
+* LWSTDAPI_(BOOL) PathCompactPathExA(
+* __out_ecount(cchMax) LPSTR pszOut, // A string buffer with cch elements
+* // that will be '\0' terminated
+* // on exit.
+* LPCSTR pszSrc, // No annotation required,
+* // const implies __in.
+* UINT cchMax,
+* DWORD dwFlags
+* );
+*
+* HRESULT SHLocalAllocBytes(
+* size_t cb,
+* __deref_bcount(cb) T **ppv // A pointer whose dereference will be set
+* // to an uninitialized buffer with cb bytes.
+* );
+*
+* __inout_bcount_full(cb) : A buffer with cb elements that is fully
+* initialized at entry and exit, and may be written to by this function.
+*
+* __out_ecount_part(count, *countOut) : A buffer with count elements that
+* will be partially initialized by this function. The function indicates how
+* much it initialized by setting *countOut.

+/************************************************************************
+* Advanced Annotations
+*
+* Advanced annotations describe behavior that is not expressible with the
+* regular buffer macros. These may be used either to annotate buffer
+* parameters that involve complex or conditional behavior, or to enrich
+* existing annotations with additional information.
+*
+* __success(expr) T f() : <expr> indicates whether function f succeeded or
+* not. If <expr> is true at exit, all the function's guarantees (as given
+* by other annotations) must hold. If <expr> is false at exit, the caller
+* should not expect any of the function's guarantees to hold. If not used,
+* the function must always satisfy its guarantees. Added automatically to
+* functions that indicate success in standard ways, such as by returning an
+* HRESULT.
+*
+* __out_awcount(expr, size) T *p : Pointer p is a buffer whose size may be
+* given in either bytes or elements. If <expr> is true, this acts like
+* __out_bcount. If <expr> is false, this acts like __out_ecount. This
+* should only be used to annotate old APIs.
+*
+* __in_awcount(expr, size) T* p : Pointer p is a buffer whose size may be given
+* in either bytes or elements. If <expr> is true, this acts like
+* __in_bcount. If <expr> is false, this acts like __in_ecount. This should
+* only be used to annotate old APIs.
+*
+* __nullterminated T* p : Pointer p is a buffer that may be read or written
+* up to and including the first '\0' character or pointer. May be used on
+* typedefs, which marks valid (properly initialized) instances of that type
+* as being null-terminated.
+*
+* __nullnullterminated T* p : Pointer p is a buffer that may be read or
+* written up to and including the first sequence of two '\0' characters or
+* pointers. May be used on typedefs, which marks valid instances of that
+* type as being double-null terminated.
+*
+* __reserved T v : Value v must be 0/NULL, reserved for future use.
+*
+* __checkReturn T f(); : Return value of f must not be ignored by callers
+* of this function.
+*
+* __typefix(ctype) T v : Value v should be treated as an instance of ctype,
+* rather than its declared type when considering validity.
+*
+* __override T f(); : Specify C#-style 'override' behaviour for overriding
+* virtual methods.
+*
+* __callback T f(); : Function f can be used as a function pointer.
+*
+* __format_string T p : Pointer p is a string that contains % markers in
+* the style of printf.
+*
+* __blocksOn(resource) f(); : Function f blocks on the resource 'resource'.
+*
+* __fallthrough : Annotates switch statement labels where fall-through is
+* desired, to distinguish from forgotten break statements.
+*
+* __range(low_bnd, up_bnd) int f(): The return from the function "f" must
+* be in the inclusive numeric range [low_bnd, up_bnd].
+*
+* __in_range(low_bnd, up_bnd) int i : Precondition that integer i must be
+* in the inclusive numeric range [low_bnd, up_bnd].
+*
+* __out_range(low_bnd, up_bnd) int i : Postcondition that integer i must be
+* in the inclusive numeric range [low_bnd, up_bnd].
+*
+* __deref_in_range(low_bnd, up_bnd) int* pi : Precondition that integer *pi
+* must be in the inclusive numeric range [low_bnd, up_bnd].
+*
+* __deref_out_range(low_bnd, up_bnd) int* pi : Postcondition that integer
+* *pi must be in the inclusive numeric range [low_bnd, up_bnd].
+*
+* The first argument of a range macro may also be a C relational operator
+* (<,>,!=, ==, <=, >=).
+*
+* __range(rel_op, j) int f(): Postcondition that "f() rel_op j" must be
+* true. Note that j may be a expression known only at runtime.
+*
+* __in_range(rel_op, j) int i : Precondition that "i rel_op j" must be
+* true. Note that j may be a expression known only at runtime.
+*
+* __out_range(rel_op, j) int i : Postcondition that integer "i rel_op j"
+* must be true. Note that j may be a expression known only at runtime.
+*
+* __deref_in_range(rel_op, j) int *pi : Precondition that "*pi rel_op j"
+* must be true. Note that j may be a expression known only at runtime.
+*
+* __deref_out_range(rel_op, j) int *pi : Postcondition that "*pi rel_op j"
+* must be true. Note that j may be a expression known only at runtime.
+*
+* __in_bound int i : Precondition that integer i must be bound, but the
+* exact range can't be specified at compile time. __in_range should be
+* used if the range can be explicitly stated.
+*
+* __out_bound int i : Postcondition that integer i must be bound, but the
+* exact range can't be specified at compile time. __out_range should be
+* used if the range can be explicitly stated.
+*
+* __deref_out_bound int pi : Postcondition that integer *pi must be bound,
+* but the exact range can't be specified at compile time.
+* __deref_out_range should be used if the range can be explicitly stated.
+*
+* __assume_bound(expr); : Assume that the expression is bound to some known
+* range. This can be used to suppress integer overflow warnings on integral
+* expressions that are known to be bound due to reasons not explicit in the
+* code. Use as a statement in the body of a function.
+*
+* __allocator void f(): Function allocates memory using an integral size
+* argument

+* Macros to classify fields of structures.
+* Structure Annotations
+*
+* The buffer annotations are a convenient way of describing
+* relationships between buffers and their size on a function by
+* function basis. Very often struct or class data members have similar
+* invariants, which can be expressed directly on the type.
+*
+* Similar to our buffer annotations we can summarize all the various
+* structure annotations by one choosing an element from each column of
+* this table to build a composite annotation.
+*
+* +--------------------------------------------------+
+* | Selector | Units | Size/Init | Optional |
+* |----------+---------+------------------+----------|
+* | __field | _ecount | (size) | empty |
+* |----------+---------+------------------+----------|
+* | __struct | _bcount | _full(size) | _opt |
+* |----------+---------+------------------+----------|
+* | | _xcount | _part(size,init) | |
+* +--------------------------------------------------+
+*
+* Note that empty represents the empty string. Sometime arguments need
+* to be "floated" to the left to give us a valid annotation name. For
+* example the naive combination __field_ecount(size)_opt is actually
+* written as __field_ecount_opt(size). Not all possible combinations
+* are currently supported or sensible. See specstrings_strict.h for
+* the currently supported set. Those that are supported are documented
+* below.
+*
+*Summary of Elements
+*
+* Selector
+*
+* __field
+* The annotation should only be placed in front
+* of data members of structures and classes. The
+* data members are pointers to a block of data.
+* The annotations describe properties about the
+* size of the block of data. This can be used for
+*
+* __struct
+* The annotation should only be placed at the
+* beginning of the definition of a structure or
+* class. These annotations are used when a struct
+* or class is used as a "header" that is
+* allocated inline with a block of data and there
+* is no apparent field that represents the tail
+* end of the structure.
+*
+* Units
+*
+* _ecount
+* All size and initialization values are in terms
+* of elements of the appropriate type
+*
+* _bcount
+* All size and initialization values are in terms
+* of raw byte sizes.
+*
+* _xcount
+* The size or initialization values cannot be
+* properly expressed as a simple byte or element
+* count, and instead a place holder is used to
+* document the relationship.
+*
+* Size/Init
+* All the size/init expressions can contain references to
+* other fields in the struct or class.
+*
+* (size)
+* The size of the buffer is determined by the
+* expression size. Unless, the type of the buffer
+* provides more information nothing is know about
+* how much of this data is initialized. For
+* example, if the data member happens to be a
+* string type such as LPSTR. It is assumed that
+* the data is initialized to the first '\0'.
+*
+* _full(size)
+* The size of the buffer is determined by the
+* expression size and all the data in the buffer
+* is guaranteed to be initialized.
+*
+* _part(size,init)
+* The size of the buffer is determined by the
+* expression size and all the data in the buffer
+* is guaranteed to be initialized up to init
+* elements or bytes.
+*
+* Optional
+*
+* empty
+* The pointer to the block of memory is never
+* NULL
+*
+* _opt
+* The pointer to the block of memory is may be
+* NULL
+*
+*
+* // Basic Usage of Struct Annotations
+* #include <stdio.h>
+* #include <stdlib.h>
+* struct buf_s {
+* int sz;
+* __field_bcount_full(sz)
+* char *buf;
+* };

+#define REENTRANT_MODE 1
+/*
+ DESCRIPTION OF COMPILER FLAG REENTRANT_MODE:
+
+ //#define REENTRANT_MODE 1
+
+ This compiler flag is related to the capability of banded decode
+ (decoding only one MB row of the source JPEG XR image at a time).
+
+ With REENTRANT_MODE defined, the decoder decodes one MB row on each call to
+ ImageStrDecDecode().
+
+ The decoder acts as if it can only write to the single MBRow whose pointer was passed to it.
+ This acts as a proof of concept that the API would work if you passed it a small buffer
+ on each call to ImageStrDecDecode().
+
+ The REENTRANT_MODE flag only works when the output image is in Orientations 0, 1
+ (vertically flipped) or 2 (horizontally flipped).
+
+ With REENTRANT_MODE defined, the function PKImageDecode_Copy_WMP()
+ decodes only as far as the pRect parameter indicates. The width of the rectangle must be the width
+ of the image, but on each call, this function will decode the image up to the end of the MB Row
+ which contains the i-th pixel row, where i = pRect->Y.
+
+ A target use of this version would be to have PKImageDecode_Copy_WMP() called in a loop, once for
+ each MB row. On each call, pRect would specify a 1-MB-Row-tall rectangle that is the width of the
+ image. The decoder state is preserved until the Decoder finishes decoding the image.
+
+ If, at a certain point, a request is made for a rectangle _above_ the last row decoded, then the
+ decoder instance is terminated and re-initiated, and decoding re-starts, going from the beginning
+ of the image to the end of the current rectangle.
+
+ ***
+
+ We've chosen to uncomment-out this definition in this header file. An alternate method would be
+ to allow the user to define this in the PREPROCESSOR DEFINITIONS section of the properties page
+ for each of the following projects: CommonLib, DecodeLib, JXRDecApp and JXRGlueLib.

-1.0.0 (Feb 6th 2001)
---------------------
-
-in short:
-
-First public release. Finally(!)
-
-This is the 0.9.5 CVS version, which will never be released, because I feel it
-is now ready for a public release. So apart from the version-numbers here and
-there, all other changes are listed under 0.9.5.
-
-This library will work with every MNG/JNG known and available to me. Note that
-there are still parts that need to be coded, and that MNG support is around
-90-95% (JNG at 100%). It is however compliant with the latest and greatest
-MNG 1.0 specification.
-
-I hope to dedicate a bit more time this year to finish up full support and fill
-in the remaining blanks. But this is coming out of my spare time. And extra
-help is always appreciated.
-
-Please enjoy!

- ***** this is unmaintained *****
-
-If you happen to find problems with autoconfiguration and building,
-I simply cannot help you. I'm looking for a maintainer that doesn't mind
-spending a few minutes every now and then on the next release to make sure
-things are still in working order.
-
-For the moment all autoconf stuff ahs been moved into unmaintained!!
-
-**********************************************************************
-**********************************************************************

-
-
-Configuration from CVS
-======================
-
-If you're using source checked out from CVS, rather than a source
-distribution tarball, please be aware that you can use ./autogen.sh in
-place of ./configure below.
-
-Because this is a cross-platform project, the source templates for
-the autoconf scripts are sequestered in the 'makefiles' directory.
-Running './autogen.sh' will copy them into their conventional places at
-the lop level. If you already see the files there, you don't need to
-worry about this step.
-
-Basic Installation
-==================
-
- These are generic installation instructions.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, a file
-`config.cache' that saves the results of its tests to speed up
-reconfiguring, and a file `config.log' containing compiler output
-(useful mainly for debugging `configure').
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If at some point `config.cache'
-contains results you don't want to keep, you may remove or edit it.
-
- The file `configure.in' is used to create `configure' by a program
-called `autoconf'. You only need `configure.in' if you want to change
-it or regenerate `configure' using a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system. If you're
- using `csh' on an old version of System V, you might need to type
- `sh ./configure' instead to prevent `csh' from trying to execute
- `configure' itself.
-
- Running `configure' takes awhile. While running, it prints some
- messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package.
-
- 4. Type `make install' to install the programs and any data files and
- documentation.
-
- 5. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.
-
-Compilers and Options
-=====================
-
- Some systems require unusual options for compilation or linking that
-the `configure' script does not know about. You can give `configure'
-initial values for variables by setting them in the environment. Using
-a Bourne-compatible shell, you can do that on the command line like
-this:
- CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
-
-Or on systems that have the `env' program, you can do it like this:
- env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
-
-Compiling For Multiple Architectures
-====================================
-
- You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
- If you have to use a `make' that does not supports the `VPATH'
-variable, you have to compile the package for one architecture at a time
-in the source code directory. After you have installed the package for
-one architecture, use `make distclean' before reconfiguring for another
-architecture.
-
-Installation Names
-==================
-
- By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc. You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
- Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
- There may be some features `configure' can not figure out
-automatically, but needs to determine by the type of host the package
-will run on. Usually `configure' can figure that out, but if it prints
-a message saying it can not guess the host type, give it the
-`--host=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name with three fields:
- CPU-COMPANY-SYSTEM
-
-See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the host type.
-
- If you are building compiler tools for cross-compiling, you can also
-use the `--target=TYPE' option to select the type of system they will
-produce code for and the `--build=TYPE' option to select the type of
-system on which you are compiling the package.
-
-Sharing Defaults
-================
-
- If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Operation Controls
-==================
-
- `configure' recognizes the following options to control how it
-operates.
-
-`--cache-file=FILE'
- Use and save the results of the tests in FILE instead of
- `./config.cache'. Set FILE to `/dev/null' to disable caching, for
- debugging `configure'.
-
-`--help'
- Print a summary of the options to `configure', and exit.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made. To
- suppress all normal output, redirect it to `/dev/null' (any error
- messages will still be shown).
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`--version'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`configure' also accepts some other, not widely useful, options.

-Configuration options in libmng
-===============================
-
-The library is fairly configurable through the use of a number of defines.
-Please note however that certain defines are for internal use only.
-The following list gives a summary of options that can be used externally to
-define the functionality of the library:
-
-========================================
-
-#define MNG_BUILD_DLL
-
-This is used to indicate that a "standard" DLL should result from compiling
-the library. Please note the remarks in README.dll if you intend to work
-with the library as a DLL. The purpose of this option is to ensure that
-DLL builds have the same set of functions.
-
-#define MNG_BUILD_SO
-
-This is used to indicate that a "standard" shared library (SO) should result
-from a compilation. The purpose of this option is to ensure that all
-shared libraries generated this way will have the same set of functions.
-
-#define MNG_USE_DLL / #define MNG_USE_SO
-
-These should be used when including the library header in the compilation
-of an application to indicate that the compiler/linker must take the
-necessary steps to make the binary executable to use the standard DLL
-or shared library (SO).
-
-#define MNG_SKIP_ZLIB / #define MNG_SKIP_LCMS / #define MNG_SKIP_IJG6B
-
-Use these in conjunction with MNG_USE_DLL / MNG_USE_SO. This is useful if
-you only need the external definitions of the MNG library and not the others,
-which will speed up the compilation process.
-
-#define MNG_SUPPORT_FULL / #define MNG_SUPPORT_LC / #define MNG_SUPPORT_VLC
-
-These can be used to indicate the level of MNG spec compliance required.
-Currently only full MNG compliance is supported.
-
-#define MNG_SUPPORT_IJG6B
-
-This can be used to indicate if JNG support is required. This option will
-include the IJG JPEG-library. Note that MNG_SUPPORT_FULL will automatically
-set this option. Use this only if you need JNG support with MNG-(V)LC.
-
-#define MNG_FULL_CMS / #define MNG_GAMMA_ONLY / #define MNG_NO_CMS /
-#define MNG_APP_CMS
-
-These indicate the color-correction support level of the library.
-If you are on a platform that supports lcms (Little CMS by Marti Maria Saguar)
-then it is highly recommended to define MNG_FULL_CMS.
-If your platform has it's own CMS then select MNG_APP_CMS and be sure to
-include the appropriate callbacks in your app.
-In all other cases it is recommended to define MNG_GAMMA_ONLY.
-
-#define MNG_SUPPORT_READ / #define MNG_SUPPORT_WRITE /
-#define MNG_SUPPORT_DISPLAY
-
-These indicate the high-level support for reading, writing and/or
-displaying files. Note that in order to display a file, you'll need to read
-it first. (yes, really!)
-
-#define MNG_STORE_CHUNKS
-
-This indicates that the library should store chunk-information when reading
-a file. This information can then be processed through the
-MNG_ITERATE_CHUNKS() function. Note that you must specify this option if
-you want to create and write a new file.
-
-#define MNG_ACCESS_CHUNKS
-
-This is used to indicate that the app may need access to internally stored
-chunk information. MNG_STORE_CHUNKS must be defined as well for this option
-to function properly.
-
-#define MNG_INTERNAL_MEMMNGMT
-
-You can use this to have the library handle it's own memory allocation and
-deallocation through the "standard" memory functions. This option is turned
-off by default, which means your app must define the memory callbacks.
-
-#define MNG_ERROR_TELLTALE
-
-Set this on to allow human-readable error-messages to be included in the
-library and the error function and callback.
-
-#define MNG_BIGENDIAN_SUPPORTED
-
-This option should be used to indicate the hardware is based on big endian
-integers.
-
-#define MNG_SUPPORT_TRACE / #define MNG_TRACE_TELLTALE
-
-These two can be used when debugging an app. You'll need to have the trace
-callback setup also. This allows for a rather thorough investigation of the
-libraries function paths.
-
-========================================
-
-Any other optional defines you may encounter are for internal use only.
-please do not specify them externally. In case of doubt, consult the
-support email lists. More info can be found on http://www.libmng.com

-Packaging Libmng for distribution
----------------------------------
-
-These are some notes for those building binaries for distribution.
-
-We're interested to hear about anywhere libmng is helpful, so let us
-know if you're including it with your application or OS. Also, if your
-build is publicly accessible, we'd be happy to link to it from
-the libmng site.
-
-However, We respectfully request that you *not* distribute binaries as a
-shared library (DLL) with any of the major features disabled. While
-there is support for this in terms of #ifdef directives (in
-libmng_conf.h) and autoconf switches they are intended for embedded
-application and testing. The default compilation options support the
-full MNG specification, and we wish to avoid the confusion among
-general users that partial support would engender.
-
-
-Platform specific notes:
-
-We have a basic .spec file for generating rpms. Send us a note if you'd
-like to clean it up.

- *************************************************************************
- !!!!!!!! THIS NEXT BIT IS IMPORTANT !!!!!!!!!
- *************************************************************************
-
- If you have defined MNG_FULL_CMS (and are using lcms), you will have to
- think hard about the following routines.
-
- lcms requires 2 profiles to work off the differences in the input-image
- and the output-device. The ICC profile for the input-image will be
- embedded within it to reflect its color-characteristics, but the output
- profile depends on the output-device, which is something only *YOU* know
- about. sRGB (standard RGB) is common for x86 compatible environments
- (eg. Windows, Linux and some others)
-
- If you are compiling for a sRGB compliant system you probably won't have
- to do anything special. (unless you want to of course)
-
- If you are compiling for a non-sRGB compliant system
- (eg. SGI, Mac, Next, others...)
- you *MUST* define a proper ICC profile for the generic output-device
- associated with that platform.
-
- In either event, you may also want to offer an option to your users to
- set the profile manually, or, if you know how, set it from a
- system-defined default.
-
- TO RECAP: for sRGB systems (Windows, Linux) no action required!
- for non-sRGB systems (SGI, Mac, Next) ACTION REQUIRED!
-
- Please visit http://www.srgb.com, http://www.color.org and
- http://www.littlecms.com for more info.

How to build and install openjpeg binaries
==========================================
-UNIX/LINUX similar systems
+UNIX/LINUX/MacOSX/Windows systems
--------------------------
-1) Using autotools
-
-It is highly recommended that pkg-config is installed. If needed, you have to
-properly set the environment variable PKG_CONFIG_PATH so that the .pc files
-are found.
-
-To build from top-level directory, you can simply type:
- ./bootstrap.sh
- ./configure
- make
-
-To keep all build files in a separate directory, you can type instead:
- ./bootstrap.sh
- mkdir build
- cd build
- ../configure
- make
-
-To install:
- sudo make install
-
-To clean:
- make clean
- make distclean
-
-To build doc (requires 'doxygen' to be found on your system):
-(this will create an html directory in TOP_LEVEL/doc)
- make doc
-
-Main './configure' options (type './configure --help' for more details)
- '--enable-mj2'
- '--enable-jpwl'
- '--enable-jpip'
- '--prefix=/path/to/install/directory' (example : '--prefix=$PWD/installed')
- '--enable-debug' (default : disabled)
-
-You can also specify your own CFLAGS and LDFLAGS with (for example):
- CFLAGS="-O3 -pipe" LDFLAGS="-Wl,-s" ./configure
-
-The (optional) dependencies of some binaries are libpng, libtiff, libcms 1 or 2
-and FastCGI. Only libtiff and FastCGI have no .pc file. There should be some
-automatic detection if they are installed in /usr, /usr/local or /opt/local.
-Otherwise, you can tune their detection (as well as for libpng and libcms1 or 2
-too) with the environment variables:
-
-TIFF_CFLAGS
-TIFF_LIBS
-FCGI_CFLAGS
-FCGI_LIBS
-
-See './configure --help' output for more details.

+----------------
+API/ABI
+
+OpenJPEG strives to provide a stable API/ABI for your applications. As such it
+only exposes a limited subset of its functions. It uses a mecanism of
+exporting/hiding functions. If you are unsure which functions you can use in
+your applications, you should compile OpenJPEG using something similar to gcc:
+-fvisibility=hidden compilation flag.
+See also: http://gcc.gnu.org/wiki/Visibility
+
+On windows, MSVC directly supports export/hidding function and as such the only
+API available is the one supported by OpenJPEG.

- Removed references to png_zalloc() and png_zfree() from the manual.
- Revised PNG_FP_EXPORT and PNG_FIXED_EXPORT macros to avoid generating

- Corrected handling of the image array and the row_pointers array in example.c
- When png_set_filler is used to strip a filler channel during write, the
- code prior to 1.5 would ignore the case where the output required an
- alpha channel or when the output was a palettized PNG. In libpng-1.5 the
- ignorance was lost and libpng proceeded to strip the channel resulting
- in a bad (potential memory overwrite) failure later. This reverts
- the behavior to the pre-1.5 state but issues a warning. libpng-1.6 is
- expected to issue an error on the erroneous png_set_filler call.
- Use png_memset() consistently (pngmem.c contained some bare "memset" calls).

Version 1.5.7 [December 15, 2011]
Minor fixes to pngvalid.c for gcc 4.6.2 compatibility to remove warnings
reported by earlier versions.
-
-Version 1.5.8beta01 [January 15, 2011]
- Removed '#include config.h"' from contrib/libtests/pngvalid.c. It's not
- needed and causes trouble for VPATH building.
+ Fixed minor memset/sizeof errors in pngvalid.c.
+
+Version 1.6.0beta01 [December 15, 2011]
+ Removed machine-generated configure files from the GIT repository (they will
+ continue to appear in the tarball distributions and in the libpng15 and
+ earlier GIT branches).
+ Restored the new 'simplified' API, which was started in libpng-1.5.7beta02
+ but later deleted from libpng-1.5.7beta05.
+ Added example programs for the new 'simplified' API.
+ Added ANSI-C (C90) headers and require them, and take advantage of the
+ change. Also fixed some of the projects/* and contrib/* files that needed
+ updates for libpng16 and the move of pngvalid.c.
+ With this change the required ANSI-C header files are assumed to exist: the
+ implementation must provide float.h, limits.h, stdarg.h and stddef.h and
+ libpng relies on limits.h and stddef.h existing and behaving as defined
+ (the other two required headers aren't used). Non-ANSI systems that don't
+ have stddef.h or limits.h will have to provide an appropriate fake
+ containing the relevant types and #defines.
+ The use of FAR/far has been eliminated and the definition of png_alloc_size_t
+ is now controlled by a flag so that 'small size_t' systems can select it
+ if necessary. Libpng 1.6 may not currently work on such systems -- it
+ seems likely that it will ask 'malloc' for more than 65535 bytes with any
+ image that has a sufficiently large row size (rather than simply failing
+ to read such images).
+ New tools directory containing tools used to generate libpng code.
+ Fixed race conditions in parallel make builds. With higher degrees of
+ parallelism during 'make' the use of the same temporary file names such
+ as 'dfn*' can result in a race where a temporary file from one arm of the
+ build is deleted or overwritten in another arm. This changes the
+ temporary files for suffix rules to always use $* and ensures that the
+ non-suffix rules use unique file names.
+
+Version 1.6.0beta02 [December 21, 2011]
+ Correct configure builds where build and source directories are separate.
+ The include path of 'config.h' was erroneously made relative in pngvalid.c
+ in libpng 1.5.7.
+
+Version 1.6.0beta03 [December 22, 2011]
+ Start-up code size improvements, error handler flexibility. These changes
+ alter how the tricky allocation of the initial png_struct and png_info
+ structures are handled. png_info is now handled in pretty much the same
+ way as everything else, except that the allocations handle NULL return
+ silently. png_struct is changed in a similar way on allocation and on
+ deallocation a 'safety' error handler is put in place (which should never
+ be required). The error handler itself is changed to permit mismatches
+ in the application and libpng error buffer size; however, this means a
+ silent change to the API to return the jmp_buf if the size doesn't match
+ the size from the libpng compilation; libpng now allocates the memory and
+ this may fail. Overall these changes result in slight code size
+ reductions; however, this is a reduction in code that is always executed
+ so is particularly valuable. Overall on a 64-bit system the libpng DLL
+ decreases in code size by 1733 bytes. pngerror.o increases in size by
+ about 465 bytes because of the new functionality.
+ Added png_convert_to_rfc1123_buffer() and deprecated png_convert_to_rfc1123()
+ to avoid including a spurious buffer in the png_struct.
+
+Version 1.6.0beta04 [December 30, 2011]
+ Regenerated configure scripts with automake-1.11.2
+ Eliminated png_info_destroy(). It is now used only in png.c and only calls
+ one other internal function and memset().
+ Enabled png_get_sCAL_fixed() if floating point APIs are enabled. Previously
+ it was disabled whenever internal fixed point arithmetic was selected,
+ which meant it didn't exist even on systems where FP was available but not
+ preferred.
+ Added pngvalid.c compile time checks for const APIs.
+ Implemented 'restrict' for png_info and png_struct. Because of the way
+ libpng works both png_info and png_struct are always accessed via a
+ single pointer. This means adding C99 'restrict' to the pointer gives
+ the compiler some opportunity to optimize the code. This change allows
+ that.
Moved AC_MSG_CHECKING([if libraries can be versioned]) later to the proper
location in configure.ac (Gilles Espinasse).
+ Changed png_memcpy to C assignment where appropriate. Changed all those
+ uses of png_memcpy that were doing a simple assignment to assignments
+ (all those cases where the thing being copied is a non-array C L-value).
+ Added some error checking to png_set_*() routines.
+ Removed the reference to the non-exported function png_memcpy() from
+ example.c.
+ Fixed the Visual C 64-bit build - it requires jmp_buf to be aligned, but
+ it had become misaligned.
+ Revised contrib/pngminus/pnm2png.c to avoid warnings when png_uint_32
+ and unsigned long are of different sizes.
+
+Version 1.6.0beta05 [January 15, 2012]
+ Updated manual with description of the simplified API (copied from png.h)
Fix bug in pngerror.c: some long warnings were being improperly truncated
(CVE-2011-3464, bug introduced in libpng-1.5.3beta05).
-Version 1.5.8rc01 [January 21, 2012]
- No changes.
-
-Version 1.5.8rc02 [January 25, 2012]
+Version 1.6.0beta06 [January 24, 2012]
+ Added palette support to the simplified APIs. This commit
+ changes some of the macro definitions in png.h, app code
+ may need corresponding changes.
+ Increased the formatted warning buffer to 192 bytes.
+ Added color-map support to simplified API. This is an initial version for
+ review; the documentation has not yet been updated.
Fixed Min/GW uninstall to remove libpng.dll.a
- Conditionalize the install rules for MINGW and CYGWIN in CMakeLists.txt
-
-Version 1.5.8 [February 1, 2012]
- No changes.
-Version 1.5.9beta01 [February 3, 2012]
- Rebuilt configure scripts in the tar distributions.
+Version 1.6.0beta07 [January 28, 2012]
+ Eliminated Intel icc/icl compiler warnings. The Intel (GCC derived)
+ compiler issues slightly different warnings from those issued by the
+ current vesions of GCC. This eliminates those warnings by
+ adding/removing casts and small code rewrites.
+ Updated configure.ac from autoupdate: added --enable-werror option.
+ Also some layout regularization and removal of introduced tab characters
+ (replaced with 3-character indentation). Obsolete macros identified by
+ autoupdate have been removed; the replacements are all in 2.59 so
+ the pre-req hasn't been changed. --enable-werror checks for support
+ for -Werror (or the given argument) in the compiler. This mimics the
+ gcc configure option by allowing -Werror to be turned on safely; without
+ the option the tests written in configure itself fail compilation because
+ they cause compiler warnings.
+ Rewrote autogen.sh to run autoreconf instead of running tools one-by-one.
+ Conditionalize the install rules for MINGW and CYGWIN in CMakeLists.txt and
+ set CMAKE_LIBRARY_OUTPUT_DIRECTORY to "lib" on all platforms (C. Yapp).
+ Freeze libtool files in the 'scripts' directory. This version of autogen.sh
+ attempts to dissuade people from running it when it is not, or should not,
+ be necessary. In fact, autogen.sh does not work when run in a libpng
+ directory extracted from a tar distribution anymore. You must run it in
+ a GIT clone instead.
+ Added two images to contrib/pngsuite (1-bit and 2-bit transparent grayscale),
+ and renamed three whose names were inconsistent with those in
+ pngsuite/README.txt.
-Version 1.5.9beta02 [February 16, 2012]
- Removed two unused definitions from scripts/pnglibconf.h.prebuilt
+Version 1.6.0beta08 [February 1, 2012]
+ Fixed Image::colormap misalignment in pngstest.c
+ Check libtool/libtoolize version number (2.4.2) in configure.ac
+ Divide test-pngstest.sh into separate pngstest runs for basic and
+ transparent images.
+ Moved automake options to AM_INIT_AUTOMAKE in configure.ac
+ Added color-tests, silent-rules (Not yet implemented in Makefile.am) and
+ version checking to configure.ac
+ Improved pngstest speed by not doing redundant tests and add const to
+ the background parameter of png_image_finish_read. The --background
+ option is now done automagically only when required, so that commandline
+ option no longer exists.
+ Cleaned up pngpriv.h to consistently declare all functions and data.
+ Also eliminated PNG_CONST_DATA, which is apparently not needed but we
+ can't be sure until it is gone.
+ Added symbol prefixing that allows all the libpng external symbols
+ to be prefixed (suggested by Reuben Hawkins).
+ Updated "ftbb*.png" list in the owatcom and vstudio projects.
+ Fixed 'prefix' builds on clean systems. The generation of pngprefix.h
+ should not require itself.
+ Updated INSTALL to explain that autogen.sh must be run in a GIT clone,
+ not in a libpng directory extracted from a tar distribution.
+
+Version 1.6.0beta09 [February 1, 2012]
+ Reverted the prebuilt configure files to libpng-1.6.0beta05 condition.
+
+Version 1.6.0beta10 [February 3, 2012]
+ Added Z_SOLO for zlib-1.2.6+ and correct pngstest tests
+ Updated list of test images in CMakeLists.txt
+ Updated the prebuilt configure files to current condition.
+ Revised INSTALL information about autogen.sh; it works in tar distributions.
+
+Version 1.6.0beta11 [February 16, 2012]
+ Fix character count in pngstest command in projects/owatcom/pngstest.tgt
+ Revised test-pngstest.sh to report PASS/FAIL for each image.
+ Updated documentation about the simplified API.
+ Corrected estimate of error in libpng png_set_rgb_to_gray API. The API is
+ extremely inaccurate for sRGB conversions because it uses an 8-bit
+ intermediate linear value and it does not use the sRGB transform, so it
+ suffers from the known instability in gamma transforms for values close
+ to 0 (see Poynton). The net result is that the calculation has a maximum
+ error of 14.99/255; 0.5/255^(1/2.2). pngstest now uses 15 for the
+ permitted 8-bit error. This may still not be enough because of arithmetic
+ error.
Removed some unused arrays (with #ifdef) from png_read_push_finish_row().
+ Fixed a memory overwrite bug in simplified read of RGB PNG with
+ non-linear gamma Also bugs in the error checking in pngread.c and changed
+ quite a lot of the checks in pngstest.c to be correct; either correctly
+ written or not over-optimistic. The pngstest changes are insufficient to
+ allow all possible RGB transforms to be passed; pngstest cmppixel needs
+ to be rewritten to make it clearer which errors it allows and then changed
+ to permit known inaccuracies.
Removed tests for no-longer-used *_EMPTY_PLTE_SUPPORTED from pngstruct.h
-
-Version 1.5.9rc01 [February 17, 2012]
+ Fixed fixed/float API export conditionals. 1) If FIXED_POINT or
+ FLOATING_POINT options were switched off, png.h ended up with lone ';'
+ characters. This is not valid ANSI-C outside a function. The ';'
+ characters have been moved inside the definition of PNG_FP_EXPORT and
+ PNG_FIXED_EXPORT. 2) If either option was switched off, the declaration
+ of the corresponding functions were completely omitted, even though some
+ of them are still used internally. The result is still valid, but
+ produces warnings from gcc with some warning options (including -Wall). The
+ fix is to cause png.h to declare the functions with PNG_INTERNAL_FUNCTION
+ when png.h is included from pngpriv.h.
+ Check for invalid palette index while reading paletted PNG. When one is
+ found, issue a warning and increase png_ptr->num_palette accordingly.
+ Apps are responsible for checking to see if that happened.
+
+Version 1.6.0beta12 [February 18, 2012]
+ Do not increase num_palette on invalid_index.
+ Relocated check for invalid palette index to pngrtran.c, after unpacking
+ the sub-8-bit pixels.
Fixed CVE-2011-3026 buffer overrun bug. This bug was introduced when
iCCP chunk support was added at libpng-1.0.6. Deal more correctly with the
test on iCCP chunk length. Also removed spurious casts that may hide
problems on 16-bit systems.
-Version 1.5.9 [February 18, 2012]
- No changes.
-
-Version 1.5.10beta01 [February 24, 2012]
- Removed two useless #ifdef directives from pngread.c and one from pngrutil.c
- Always put the CMAKE_LIBRARY in "lib" (removed special WIN32 case).
- Removed empty vstudio/pngstest directory (Clifford Yapp).
+Version 1.6.0beta13 [February 24, 2012]
Eliminated redundant png_push_read_tEXt|zTXt|iTXt|unknown code from
pngpread.c and use the sequential png_handle_tEXt, etc., in pngrutil.c;
now that png_ptr->buffer is inaccessible to applications, the special
handling is no longer useful.
- Fixed bug with png_handle_hIST with odd chunk length (Frank Busse).
- Added PNG_SAFE_LIMITS feature to pnglibconf.dfa and code in pngconf.h
- to reset the user limits to safe ones if PNG_SAFE_LIMITS is defined.
- To enable, use "CPPFLAGS=-DPNG_SAFE_LIMITS_SUPPORTED" on the configure
- command or put "#define PNG_SAFE_LIMITS_SUPPORTED" in pnglibconf.h.
- Revised the SAFE_LIMITS feature to be the same as the feature in libpng16.
- Added information about the new limits in the manual.
+ Added PNG_SAFE_LIMITS feature to pnglibconf.dfa, pngpriv.h, and new
+ pngusr.dfa to reset the user limits to safe ones if PNG_SAFE_LIMITS is
+ defined. To enable, use "CPPFLAGS=-DPNG_SAFE_LIMITS_SUPPORTED=1" on the
+ configure command or put #define PNG_SAFE_LIMITS_SUPPORTED in
+ pnglibconf.h.prebuilt and pnglibconf.h.
-Version 1.5.10beta02 [February 27, 2012]
+Version 1.6.0beta14 [February 27, 2012]
+ Added information about the new limits in the manual.
Updated Makefile.in
-Version 1.5.10beta03 [March 6, 2012]
+Version 1.6.0beta15 [March 2, 2012]
Removed unused "current_text" members of png_struct and the png_free()
of png_ptr->current_text from pngread.c
- Added palette-index checking. Issue a png_warning() if an invalid index is
- found.
-
-Version 1.5.10beta04 [March 10, 2012]
- Fixed PNG_LIBPNG_BUILD_BASE_TYPE definition.
- Fixed CMF optimization of non-IDAT compressed chunks, which was added at
- libpng-1.5.4. It sometimes produced too small of a window.
-
-Version 1.5.10beta05 [March 10, 2012]
+ Rewrote pngstest.c for substantial speed improvement.
+ Fixed transparent pixel and 16-bit rgb tests in pngstest and removed a
+ spurious check in pngwrite.c
+ Added PNG_IMAGE_FLAG_FAST for the benefit of applications that store
+ intermediate files, or intermediate in-memory data, while processing
+ image data with the simplified API. The option makes the files larger
+ but faster to write and read. pngstest now uses this by default; this
+ can be disabled with the --slow option.
+ Improved pngstest fine tuning of error numbers, new test file generator.
+ The generator generates images that test the full range of sample values,
+ allow the error numbers in pngstest to be tuned and checked. makepng
+ also allows generation of images with extra chunks, although this is
+ still work-in-progress.
+ Added check for invalid palette index while reading.
+ Fixed some bugs in ICC profile writing. The code should now accept
+ all potentially valid ICC profiles and reject obviously invalid ones.
+ It now uses png_error() to do so rather than casually writing a PNG
+ without the necessary color data.
+ Removed whitespace from the end of lines in all source files and scripts.
+
+Version 1.6.0beta16 [March 6, 2012]
+ Relocated palette-index checking function from pngrutil.c to pngtrans.c
+ Added palette-index checking while writing.
+ Changed png_inflate() and calling routines to avoid overflow problems.
+ This is an intermediate check-in that solves the immediate problems and
+ introduces one performance improvement (avoiding a copy via png_ptr->zbuf.)
+ Further changes will be made to make ICC profile handling more secure.
+ Fixed build warnings (MSVC, GCC, GCC v3). Cygwin GCC with default options
+ declares 'index' as a global, causing a warning if it is used as a local
+ variable. GCC 64-bit warns about assigning a (size_t) (unsigned 64-bit)
+ to an (int) (signed 32-bit). MSVC, however, warns about using the
+ unary '-' operator on an unsigned value (even though it is well defined
+ by ANSI-C to be ~x+1). The padding calculation was changed to use a
+ different method. Removed the tests on png_ptr->pass.
+ Added contrib/libtests/tarith.c to test internal arithmetic functions from
+ png.c. This is a libpng maintainer program used to validate changes to the
+ internal arithmetic functions.
+ Made read 'inflate' handling like write 'deflate' handling. The read
+ code now claims and releases png_ptr->zstream, like the write code.
+ The bug whereby the progressive reader failed to release the zstream
+ is now fixed, all initialization is delayed, and the code checks for
+ changed parameters on deflate rather than always calling
+ deflatedEnd/deflateInit.
+ Validate the zTXt strings in pngvalid.
+ Added code to validate the windowBits value passed to deflateInit2().
+ If the call to deflateInit2() is wrong a png_warning will be issued
+ (in fact this is harmless, but the PNG data produced may be sub-optimal).
+
+Version 1.6.0beta17 [March 10, 2012]
+ Fixed PNG_LIBPNG_BUILD_BASE_TYPE definition.
Reject all iCCP chunks after the first, even if the first one is invalid.
+ Deflate/inflate was reworked to move common zlib calls into single
+ functions [rw]util.c. A new shared keyword check routine was also added
+ and the 'zbuf' is no longer allocated on progressive read. It is now
+ possible to call png_inflate() incrementally. A warning is no longer
+ issued if the language tag or translated keyword in the iTXt chunk
+ has zero length.
+ If benign errors are disabled use maximum window on ancilliary inflate.
+ This works round a bug introduced in 1.5.4 where compressed ancillary
+ chunks could end up with a too-small windowBits value in the deflate
+ header.
+
+Version 1.6.0beta18 [March 16, 2012]
Issue a png_benign_error() instead of png_warning() about bad palette index.
+ In pngtest, treat benign errors as errors if "-strict" is present.
Fixed an off-by-one error in the palette index checking function.
+ Fixed a compiler warning under Cygwin (Windows-7, 32-bit system)
Revised example.c to put text strings in a temporary character array
instead of directly assigning string constants to png_textp members.
This avoids compiler warnings when -Wwrite-strings is enabled.
-
-Version 1.5.10 [March 29, 2012]
+ Added output flushing to aid debugging under Visual Studio. Unfortunately
+ this is necessary because the VS2010 output window otherwise simply loses
+ the error messages on error (they weren't flushed to the window before
+ the process exited, apparently!)
+ Added configuration support for benign errors and changed the read
+ default. Also changed some warnings in the iCCP and sRGB handling
+ from to benign errors. Configuration now makes read benign
+ errors warnings and write benign errors to errors by default (thus
+ changing the behavior on read). The simplified API always forces
+ read benign errors to warnings (regardless of the system default, unless
+ this is disabled in which case the simplified API can't be built.)
+
+Version 1.6.0beta19 [March 18, 2012]
+ Work around for duplicate row start calls; added warning messages.
+ This turns on PNG_FLAG_DETECT_UNINITIALIZED to detect app code that
+ fails to call one of the 'start' routines (not enabled in libpng-1.5
+ because it is technically an API change, since it did normally work
+ before.) It also makes duplicate calls to png_read_start_row (an
+ internal function called at the start of the image read) benign, as
+ they were before changes to use png_inflate_claim. Somehow webkit is
+ causing this to happen; this is probably a mis-feature in the zlib
+ changes so this commit is only a work-round.
+ Removed erroneous setting of DETECT_UNINITIALIZED and added more
+ checks. The code now does a png_error if an attempt is made to do the
+ row initialization twice; this is an application error and it has
+ serious consequences because the transform data in png_struct is
+ changed by each call.
+ Added application error reporting and added chunk names to read
+ benign errors; also added --strict to pngstest - not enabled
+ yet because a warning is produced.
+ Avoid the double gamma correction warning in the simplified API.
+ This allows the --strict option to pass in the pngstest checks
+
+Version 1.6.0beta20 [March 29, 2012]
+ Changed chunk handler warnings into benign errors, incrementally load iCCP
+ Added checksum-icc.c to contrib/tools
Prevent PNG_EXPAND+PNG_SHIFT doing the shift twice.
+ Recognize known sRGB ICC profiles while reading; prefer writing the
+ iCCP profile over writing the sRGB chunk, controlled by the
+ PNG_sRGB_PROFILE_CHECKS option.
Revised png_set_text_2() to avoid potential memory corruption (fixes
CVE-2011-3048, also known as CVE-2012-3425).
-Version 1.5.11beta01 [April 28, 2012]
+Version 1.6.0beta21 [April 27, 2012]
Revised scripts/makefile.darwin: use system zlib; remove quotes around
architecture list; add missing ppc architecture; add architecture options
to shared library link; don't try to create a shared lib based on missing
RELEASE variable.
Enable png_set_check_for_invalid_index() for both read and write.
- Removed #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED/#endif in pngpriv.h around
+ Removed #ifdef PNG_HANDLE_AS_UNKNOWN_SUPPORTED in pngpriv.h around
declaration of png_handle_unknown().
Added -lssp_nonshared in a comment in scripts/makefile.freebsd
and changed deprecated NOOBJ and NOPROFILE to NO_OBJ and NO_PROFILE.
-Version 1.5.11rc01 [May 23, 2012]
- No changes.
+Version 1.6.0beta22 [May 23, 2012]
+ Removed need for -Wno-cast-align with clang. clang correctly warns on
+ alignment increasing pointer casts when -Wcast-align is passed. This
+ fixes the cases that clang warns about either by eliminating the
+ casts from png_bytep to png_uint_16p (pngread.c), or, for pngrutil.c
+ where the cast is previously verified or pngstest.c where it is OK, by
+ introducing new png_aligncast macros to do the cast in a way that clang
+ accepts.
-Version 1.5.11rc02 [May 29, 2012]
- Fixed some typos in comments.
+Version 1.6.0beta23 [June 6, 2012]
Revised CMakeLists.txt to not attempt to make a symlink under mingw.
- Added two images to contrib/pngsuite (1-bit and 2-bit transparent grayscale),
- and renamed three whose names were inconsistent with those in
- pngsuite/README.txt.
-
-Version 1.5.11rc03 [June 4, 2012]
- Do not depend upon a GCC feature macro being available for use in generating
- the linker mapfile symbol prefix.
Made fixes for new optimization warnings from gcc 4.7.0. The compiler
- performed an optimization which is safe but then warned about it.
+ performs an optimization which is safe; however it then warns about it.
Changing the type of 'palette_number' in pngvalid.c removes the warning.
+ Do not depend upon a GCC feature macro being available for use in generating
+ the linker mapfile symbol prefix.
+ Improved performance of new do_check_palette_indexes() function (only
+ update the value when it actually increases, move test for whether
+ the check is wanted out of the function.
-Version 1.5.11rc04 [June 6, 2012]
- Improved performance of new do_check_palette_indexes() function.
-
-Version 1.5.11rc05 [June 7, 2012]
+Version 1.6.0beta24 [June 7, 2012]
Don't check palette indexes if num_palette is 0 (as it can be in MNG files).
-Version 1.5.11 [June 14, 2012]
- Include zlib.h in contrib/gregbook and contrib/visupng examples.
+Version 1.6.0beta25 [June 16, 2012]
+ Revised png_set_keep_unknown_chunks() so num_chunks < 0 means ignore all
+ unknown chunks and all known chunks except for IHDR, PLTE, tRNS, IDAT,
+ and IEND. Previously it only meant ignore all unknown chunks, the
+ same as num_chunks == 0. Revised png_image_skip_unused_chunks() to
+ provide a list of chunks to be processed instead of a list of chunks to
+ ignore. Revised contrib/gregbook/readpng2.c accordingly.
-Version 1.5.12 [July 11, 2012]
+Version 1.6.0beta26 [July 10, 2012]
Removed scripts/makefile.cegcc from the *.zip and *.7z distributions; it
depends on configure, which is not included in those archives.
+ Moved scripts/chkfmt to contrib/tools.
Changed "a+w" to "u+w" in Makefile.in to fix CVE-2012-3386.
-Version 1.5.13beta01 [August 8, 2012]
+Version 1.6.0beta27 [August 11, 2012]
Do not compile PNG_DEPRECATED, PNG_ALLOC and PNG_PRIVATE when __GNUC__ < 3.
+ Do not use __restrict when GNUC is <= 3.1
Removed references to png_zalloc() and png_zfree() from the manual.
- Revised PNG_FP_EXPORT and PNG_FIXED_EXPORT macros to avoid generating
- lone semicolons (patch ported from libpng-1.6.0beta11).
-
-Version 1.5.13beta02 [September 10, 2012]
- Corrected handling of the image array and the row_pointers array in example.c
- When png_set_filler is used to strip a filler channel during write, the
- code prior to 1.5 would ignore the case where the output required an
- alpha channel or when the output was a palettized PNG. In libpng-1.5 the
- ignorance was lost and libpng proceeded to strip the channel resulting
- in a bad (potential memory overwrite) failure later. This reverts
- the behavior to the pre-1.5 state but issues a warning. libpng-1.6 is
- expected to issue an error on the erroneous png_set_filler call.
- Use png_memset() consistently (pngmem.c contained some bare "memset" calls).
-
-Version 1.5.13rc01 [September 17, 2012]
+ Fixed configurations where floating point is completely disabled. Because
+ of the changes to support symbol prefixing PNG_INTERNAL_FUNCTION declares
+ floating point APIs during libpng builds even if they are completely
+ disabled. This requires the png floating point types (png_double*) to be
+ declared even though the functions are never actually defined. This
+ change provides a dummy definition so that the declarations work, yet any
+ implementation will fail to compile because of an incomplete type.
+ Re-eliminated the use of strcpy() in pngtest.c. An unncessary use of
+ strcpy() was accidentally re-introduced in libpng16; this change replaces
+ it with strncpy().
+ Eliminated use of png_sizeof(); use sizeof() instead.
+ Use a consistent style for (sizeof type) and (sizeof (array))
+ Cleanup of png_set_filler(). This function does very different things on
+ read and write. In libpng 1.6 the two cases can be distinguished and
+ considerable code cleanup, and extra error checking, is possible. This
+ makes calls on the write side that have no effect be ignored with a
+ png_app_error(), which can be disabled in the app using
+ png_set_benign_errors(), and removes the spurious use of usr_channels
+ on the read side.
+ Insist on autotools 1.12.1 for git builds because there are security issues
+ with 1.12 and insisting on anything less would allow 1.12 to be used.
+ Removed info_ptr->signature[8] from WRITE-only builds.
+ Add some conditions for compiling png_fixed(). This is a small function
+ but it requires "-lm" on some platforms.
+ Cause pngtest --strict to fail on any warning from libpng (not just errors)
+ and cause it not to fail at the comparison step if libpng lacks support
+ for writing chunks that it reads from the input (currently only implemented
+ for compressed text chunks).
+ Make all three "make check" test programs work without READ or WRITE support.
+ Now "make check" will succeed even if libpng is compiled with -DPNG_NO_READ
+ or -DPNG_NO_WRITE. The tests performed are reduced, but the basic reading
+ and writing of a PNG file is always tested by one or more of the tests.
+ Consistently use strlen(), memset(), memcpy(), and memcmp() instead of the
+ png_strlen(), png_memset(), png_memcpy(), and png_memcmp() macros.
+ Removed the png_sizeof(), png_strlen(), png_memset(), png_memcpy(), and
+ png_memcmp() macros.
+ Work around gcc 3.x and Microsoft Visual Studio 2010 complaints. Both object
+ to the split initialization of num_chunks.
+
+Version 1.6.0beta28 [August 29, 2012]
+ Unknown handling fixes and clean up. This adds more correct option
+ control of the unknown handling, corrects the pre-existing bug where
+ the per-chunk 'keep' setting is ignored and makes it possible to skip
+ IDAT chunks in the sequential reader (broken in earlier 1.6 versions).
+ There is a new test program, test-unknown.c, which is a work in progress
+ (not currently part of the test suite). Comments in the header files now
+ explain how the unknown handling works.
+ Allow fine grain control of unknown chunk APIs. This change allows
+ png_set_keep_unknown_chunks() to be turned off if not required and causes
+ both read and write to behave appropriately (on read this is only possible
+ if the user callback is used to handle unknown chunks). The change
+ also removes the support for storing unknown chunks in the info_struct
+ if the only unknown handling enabled is via the callback, allowing libpng
+ to be configured with callback reading and none of the unnecessary code.
+ Corrected fix for unknown handling in pngtest. This reinstates the
+ libpng handling of unknown chunks other than vpAg and sTER (including
+ unsafe-to-copy chunks which were dropped before) and eliminates the
+ repositioning of vpAg and sTER in pngtest.png by changing pngtest.png
+ (so the chunks are where libpng would put them).
+ Added "tunknown" test and corrected a logic error in png_handle_unknown()
+ when SAVE support is absent. Moved the shell test scripts for
+ contrib/libtests from the libpng top directory to contrib/libtests.
+ png_handle_unknown() must always read or skip the chunk, if
+ SAVE_UNKNOWN_CHUNKS is turned off *and* the application does not set
+ a user callback an unknown chunk will not be read, leading to a read
+ error, which was revealed by the "tunknown" test.
+ Cleaned up and corrected ICC profile handling.
+ contrib/libtests/makepng: corrected 'rgb' and 'gray' cases. profile_error
+ messages could be truncated; made a correct buffer size calculation and
+ adjusted pngerror.c appropriately. png_icc_check_* checking improved;
+ changed the functions to receive the correct color type of the PNG on read
+ or write and check that it matches the color space of the profile (despite
+ what the comments said before, there is danger in assuming the app will
+ cope correctly with an RGB profile on a grayscale image and, since it
+ violates the PNG spec, allowing it is certain to produce inconsistent
+ app behavior and might even cause app crashes.) Check that profiles
+ contain the tags needed to process the PNG (tags all required by the ICC
+ spec). Removed unused PNG_STATIC from pngpriv.h.
+
+Version 1.6.0beta29 [September 4, 2012]
+ Fixed the simplified API example programs to add the *colormap parameter
+ to several of he API and improved the error message if the version field
+ is not set.
+ Added contrib/examples/* to the *.zip and *.7z distributions.
+ Updated simplified API synopses and description of the png_image structure
+ in the manual.
+ Made makepng and pngtest produce identical PNGs, add "--relaxed" option
+ to pngtest. The "--relaxed" option turns off the benign errors that are
+ enabled by default in pre-RC builds. makepng can now write ICC profiles
+ where the length has not been extended to a multiple of 4, and pngtest
+ now intercepts all libpng errors, allowing the previously-introduced
+ "--strict test" on no warnings to actually work.
+ Improved ICC profile handling including cHRM chunk generation and fixed
+ Cygwin+MSVC build errors. The ICC profile handling now includes more
+ checking. Several errors that caused rejection of the profile are now
+ handled with a warning in such a way that the invalid profiles will be
+ read by default in release (but not pre-RC) builds but will not be
+ written by default. The easy part of handling the cHRM chunk is written,
+ where the ICC profile contains the required data. The more difficult
+ part plus guessing a gAMA value requires code to pass selected RGB values
+ through the profile.
+
+Version 1.6.0beta30 [October 24, 2012]
+ Changed ICC profile matrix/vector types to not depend on array type rules.
+ By the ANSI-C standard the new types should be identical to the previous
+ versions, and all known versions of gcc tested with the previous versions
+ except for GCC-4.2.1 work with this version. The change makes the ANSI-C
+ rule that const applied to an array of elements applies instead to the
+ elements in the array moot by explicitly applying const to the base
+ elements of the png_icc_matrix and png_icc_vector types. The accidental
+ (harmless) 'const' previously applied to the parameters of two of the
+ functions have also been removed.
+ Added a work around for GCC 4.2 optimization bug.
+ Marked the broken (bad white point) original HP sRGB profiles correctly and
+ correct comments.
+ Added -DZ_SOLO to contrib/pngminim/*/makefile to work with zlib-1.2.7
+ Use /MDd for vstudio debug builds. Also added pngunkown to the vstudio
+ builds, fixed build errors and corrected a minor exit code error in
+ pngvalid if the 'touch' file name is invalid.
+ Add updated WARNING file to projects/vstudio from libpng 1.5/vstudio
+ Fixed build when using #define PNG_NO_READ_GAMMA in png_do_compose() in
+ pngrtran.c (Domani Hannes).
+
+Version 1.6.0beta31 [November 1, 2012]
+ Undid the erroneous change to vstudio/pngvalid build in libpng-1.6.0beta30.
+ Made pngvalid so that it will build outside the libpng source tree.
+ Made builds -DPNG_NO_READ_GAMMA compile (the unit tests still fail).
+ Made PNG_NO_READ_GAMMA switch off interfaces that depend on READ_GAMMA.
+ Prior to 1.6.0 switching off READ_GAMMA did unpredictable things to the
+ interfaces that use it (specifically, png_do_background in 1.4 would
+ simply display composite for grayscale images but do composition
+ with the incorrect arithmetic for color ones). In 1.6 the semantic
+ of -DPNG_NO_READ_GAMMA is changed to simply disable any interface that
+ depends on it; this obliges people who set it to consider whether they
+ really want it off if they happen to use any of the interfaces in
+ question (typically most users who disable it won't).
+ Fixed GUIDs in projects/vstudio. Some were duplicated or missing,
+ resulting in VS2010 having to update the files.
+ Removed non-working ICC profile support code that was mostly added to
+ libpng-1.6.0beta29 and beta30. There was too much code for too little
+ gain; implementing full ICC color correction may be desireable but is left
+ up to applications.
+
+Version 1.6.0beta32 [November 25, 2012]
+ Fixed an intermittent SEGV in pngstest due to an uninitialized array element.
+ Added the ability for contrib/libtests/makepng.c to make a PNG with just one
+ color. This is useful for debugging pngstest color inaccuracy reports.
+ Fixed error checking in the simplified write API (Olaf van der Spek)
+ Made png_user_version_check() ok to use with libpng version 1.10.x and later.
+
+Version 1.6.0beta33 [December 15, 2012]
+ Fixed typo in png.c (PNG_SET_CHUNK_MALLOC_MAX should be PNG_CHUNK_MALLOC_MAX)
+ that causes the MALLOC_MAX limit not to work (John Bowler)
+ Change png_warning() to png_app_error() in pngwrite.c and comment the
+ fall-through condition.
+ Change png_warning() to png_app_warning() in png_write_tRNS().
+ Rearranged the ARM-NEON optimizations: Isolated the machine specific code
+ to the hardware subdirectory and added comments to pngrutil.c so that
+ implementors of other optimizations know what to do.
+ Fixed cases of unquoted DESTDIR in Makefile.am
+ Rebuilt Makefile.in, etc., with autoconf-2.69 and automake-1.12.5.
+
+Version 1.6.0beta34 [December 19, 2012]
+ Cleaned up whitespace in the synopsis portion of the manpage "libpng.3"
+ Disassembled the version number in scripts/options.awk (necessary for
+ building on SunOs).
+
+Version 1.6.0beta35 [December 23, 2012]
+ Made default Zlib compression settings be configurable. This adds #defines to
+ pnglibconf.h to control the defaults.
+ Fixed Windows build issues, enabled ARM compilation. Various warnings issued
+ by earlier versions of GCC fixed for Cygwin and Min/GW (which both use old
+ GCCs.) ARM support is enabled by default in zlib.props (unsupported by
+ Microsoft) and ARM compilation is made possible by deleting the check for
+ x86. The test programs cannot be run because they are not signed.
+
+Version 1.6.0beta36 [January 2, 2013]
+ Discontinued distributing libpng-1.x.x.tar.bz2.
+ Discontinued distributing libpng-1.7.0-1.6.0-diff.txt and similar.
+ Rebuilt configure with autoconf-2.69 (inadvertently not done in beta33)
+ Fixed 'make distcheck' on SUN OS - libpng.so was not being removed
+
+Version 1.6.0beta37 [January 10, 2013]
+ Fixed conceivable but difficult to repro overflow. Also added two test
+ programs to generate and test a PNG which should have the problem.
+
+Version 1.6.0beta39 [January 19, 2013]
+ Again corrected attempt at overflow detection in png_set_unknown_chunks()
+ (CVE-2013-7353). Added overflow detection in png_set_sPLT() and
+ png_set_text_2() (CVE-2013-7354).
+
+Version 1.6.0beta40 [January 20, 2013]
+ Use consistent handling of overflows in text, sPLT and unknown png_set_* APIs
+
+Version 1.6.0rc01 [January 26, 2013]
+ No changes.
+
+Version 1.6.0rc02 [February 4, 2013]
+ Added png_get_palette_max() function.
+
+Version 1.6.0rc03 [February 5, 2013]
+ Fixed the png_get_palette_max API.
+
+Version 1.6.0rc04 [February 7, 2013]
+ Turn serial tests back on (recently turned off by autotools upgrade).
+
+Version 1.6.0rc05 [February 8, 2013]
+ Update manual about png_get_palette_max().
+
+Version 1.6.0rc06 [February 9, 2013]
+ Fixed missing dependency in --prefix builds The intermediate
+ internal 'prefix.h' file can only be generated correctly after
+ pnglibconf.h, however the dependency was not in Makefile.am. The
+ symptoms are unpredictable depending on the order make chooses to
+ build pngprefix.h and pnglibconf.h, often the error goes unnoticed
+ because there is a system pnglibconf.h to use instead.
+
+Version 1.6.0rc07 [February 10, 2013]
+ Enclosed the new png_get_palette_max in #ifdef PNG_GET_PALETTE_MAX_SUPPORTED
+ block, and revised pnglibconf.h and pnglibconf.h.prebuilt accordingly.
+
+Version 1.6.0rc08 [February 10, 2013]
+ Fix typo in png.h #ifdef
+
+Version 1.6.0 [February 14, 2013]
+ No changes.
+
+Version 1.6.1beta01 [February 16, 2013]
+ Made symbol prefixing work with the ARM neon optimizations. Also allow
+ pngpriv.h to be included for preprocessor definitions only, so it can
+ be used in non-C/C++ files. Back ported from libpng 1.7.
+ Made sRGB check numbers consistent.
+ Ported libpng 1.5 options.awk/dfn file handling to 1.6, fixed one bug.
+ Removed cc -E workround, corrected png_get_palette_max API Tested on
+ SUN OS cc 5.9, which demonstrates the tokenization problem previously
+ avoided by using /lib/cpp. Since all .dfn output is now protected in
+ double quotes unless it is to be macro substituted the fix should
+ work everywhere.
+ Enabled parallel tests - back ported from libpng-1.7.
+ scripts/pnglibconf.dfa formatting improvements back ported from libpng17.
+ Fixed a race condition in the creation of the build 'scripts' directory
+ while building with a parallel make.
+ Use approved/supported Android method to check for NEON, use Linux/POSIX
+ 1003.1 API to check /proc/self/auxv avoiding buffer allocation and other
+ library calls (ported from libpng15).
+
+Version 1.6.1beta02 [February 19, 2013]
+ Use parentheses more consistently in "#if defined(MACRO)" tests.
+ Folded long lines.
+ Reenabled code to allow zero length PLTE chunks for MNG.
+
+Version 1.6.1beta03 [February 22, 2013]
+ Fixed ALIGNED_MEMORY support.
+ Allow run-time ARM NEON checking to be disabled. A new configure option:
+ --enable-arm-neon=always will stop the run-time checks. New checks
+ within arm/arm_init.c will cause the code not to be compiled unless
+ __ARM_NEON__ is set. This should make it fail safe (if someone asks
+ for it on then the build will fail if it can't be done.)
+ Updated the INSTALL document.
+
+Version 1.6.1beta04 [February 27, 2013]
+ Revised INSTALL to recommend using CPPFLAGS instead of INCLUDES.
+ Revised scripts/makefile.freebsd to respect ZLIBLIB and ZLIBINC.
+ Revised scripts/dfn.awk to work with the buggy MSYS awk that has trouble
+ with CRLF line endings.
+
+Version 1.6.1beta05 [March 1, 2013]
+ Avoid a possible memory leak in contrib/gregbook/readpng.c
+
+Version 1.6.1beta06 [March 4, 2013]
+ Better documentation of unknown handling API interactions.
+ Corrected Android builds and corrected libpng.vers with symbol
+ prefixing. This adds an API to set optimization options externally,
+ providing an alternative and general solution for the non-portable
+ run-time tests used by the ARM Neon code. It also makes those tests
+ compile and link on Android.
+ The order of settings vs options in pnglibconf.h is reversed to allow
+ settings to depend on options and options can now set (or override) the
+ defaults for settings.
+
+Version 1.6.1beta07 [March 7, 2013]
+ Corrected simplified API default gamma for color-mapped output, added
+ a flag to change default. In 1.6.0 when the simplified API was used
+ to produce color-mapped output from an input image with no gamma
+ information the gamma assumed for the input could be different from
+ that assumed for non-color-mapped output. In particular 16-bit depth
+ input files were assumed to be sRGB encoded, whereas in the 'direct'
+ case they were assumed to have linear data. This was an error. The
+ fix makes the simplified API treat all input files the same way and
+ adds a new flag to the png_image::flags member to allow the
+ application/user to specify that 16-bit files contain sRGB data
+ rather than the default linear.
+ Fixed bugs in the pngpixel and makepng test programs.
+
+Version 1.6.1beta08 [March 7, 2013]
+ Fixed CMakelists.txt to allow building a single variant of the library
+ (Claudio Bley):
+ Introduced a PNG_LIB_TARGETS variable that lists all activated library
+ targets. It is an error if this variable ends up empty, ie. you have
+ to build at least one library variant.
+ Made the *_COPY targets only depend on library targets actually being build.
+ Use PNG_LIB_TARGETS to unify a code path.
+ Changed the CREATE_SYMLINK macro to expect the full path to a file as the
+ first argument. When symlinking the filename component of that path is
+ determined and used as the link target.
+ Use copy_if_different in the CREATE_SYMLINK macro.
+
+Version 1.6.1beta09 [March 13, 2013]
+ Eliminated two warnings from the Intel C compiler. The warnings are
+ technically valid, although a reasonable treatment of division would
+ show it to be incorrect.
+
+Version 1.6.1rc01 [March 21, 2013]
+ No changes.
+
+Version 1.6.1 [March 28, 2013]
+ No changes.
+
+Version 1.6.2beta01 [April 14, 2013]
+ Updated documentation of 1.5.x to 1.6.x changes in iCCP chunk handling.
+ Fixed incorrect warning of excess deflate data. End condition - the
+ warning would be produced if the end of the deflate stream wasn't read
+ in the last row. The warning is harmless.
+ Corrected the test on user transform changes on read. It was in the
+ png_set of the transform function, but that doesn't matter unless the
+ transform function changes the rowbuf size, and that is only valid if
+ transform_info is called.
+ Corrected a misplaced closing bracket in contrib/libtests/pngvalid.c
+ (Flavio Medeiros).
+ Corrected length written to uncompressed iTXt chunks (Samuli Suominen).
+ Bug was introduced in libpng-1.6.0.
+
+Version 1.6.2rc01 [April 18, 2013]
+ Added contrib/tools/fixitxt.c, to repair the erroneous iTXt chunk length
+ written by libpng-1.6.0 and 1.6.1.
+ Disallow storing sRGB information when the sRGB is not supported.
+
+Version 1.6.2rc02 [April 18, 2013]
+ Merge pngtest.c with libpng-1.7.0
+
+Version 1.6.2rc03 [April 22, 2013]
+ Trivial spelling cleanup.
+
+Version 1.6.2rc04 and 1.6.2rc05 [omitted]
+
+Version 1.6.2rc06 [April 24, 2013]
+ Reverted to version 1.6.2rc03. Recent changes to arm/neon support
+ have been ported to libpng-1.7.0beta09 and will reappear in version
+ 1.6.3beta01.
+
+Version 1.6.2 [April 25, 2013]
+ No changes.
+
+Version 1.6.3beta01 [April 25, 2013]
+ Revised stack marking in arm/filter_neon.S and configure.ac.
+ Ensure that NEON filter stuff is completely disabled when switched 'off'.
+ Previously the ARM NEON specific files were still built if the option
+ was switched 'off' as opposed to being explicitly disabled.
+
+Version 1.6.3beta02 [April 26, 2013]
+ Test for 'arm*' not just 'arm' in the host_cpu configure variable.
+ Rebuilt the configure scripts.
+
+Version 1.6.3beta03 [April 30, 2013]
+ Expanded manual paragraph about writing private chunks, particularly
+ the need to call png_set_keep_unknown_chunks() when writing them.
+ Avoid dereferencing NULL pointer possibly returned from
+ png_create_write_struct() (Andrew Church).
+
+Version 1.6.3beta05 [May 9, 2013]
+ Calculate our own zlib windowBits when decoding rather than trusting the
+ CMF bytes in the PNG datastream.
+ Added an option to force maximum window size for inflating, which was
+ the behavior of libpng15 and earlier.
+ Added png-fix-itxt and png-fix-too-far-back to the built programs and
+ removed warnings from the source code and timepng that are revealed as
+ a result.
+ Detect wrong libpng versions linked to png-fix-too-far-back, which currently
+ only works with libpng versions that can be made to reliably fail when
+ the deflate data contains an out-of-window reference. This means only
+ 1.6 and later.
+ Fixed gnu issues: g++ needs a static_cast, gcc 4.4.7 has a broken warning
+ message which it is easier to work round than ignore.
+ Updated contrib/pngminus/pnm2png.c (Paul Stewart):
+ Check for EOF
+ Ignore "#" delimited comments in input file to pnm2png.c.
+ Fixed whitespace handling
+ Added a call to png_set_packing()
+ Initialize dimension values so if sscanf fails at least we have known
+ invalid values.
+ Attempt to detect configuration issues with png-fix-too-far-back, which
+ requires both the correct libpng and the correct zlib to function
+ correctly.
+ Check ZLIB_VERNUM for mismatches, enclose #error in quotes
+ Added information in the documentation about problems with and fixes for
+ the bad CRC and bad iTXt chunk situations.
+
+Version 1.6.3beta06 [May 12, 2013]
+ Allow contrib/pngminus/pnm2png.c to compile without WRITE_INVERT and
+ WRITE_PACK supported (writes error message that it can't read P1 or
+ P4 PBM files).
+ Improved png-fix-too-far-back usage message, added --suffix option.
+ Revised contrib/pngminim/*/makefile to generate pnglibconf.h with the
+ right zlib header files.
+ Separated CPPFLAGS and CFLAGS in contrib/pngminim/*/makefile
+
+Version 1.6.3beta07 [June 8, 2013]
+ Removed a redundant test in png_set_IHDR().
+ Added set(CMAKE_CONFIGURATION_TYPES ...) to CMakeLists.txt (Andrew Hundt)
+ Deleted set(CMAKE_BUILD_TYPE) block from CMakeLists.txt
+ Enclose the prototypes for the simplified write API in
+ #ifdef PNG_STDIO_SUPPORTED/#endif
+ Make ARM NEON support work at compile time (not just configure time).
+ This moves the test on __ARM_NEON__ into pngconf.h to avoid issues when
+ using a compiler that compiles for multiple architectures at one time.
+ Removed PNG_FILTER_OPTIMIZATIONS and PNG_ARM_NEON_SUPPORTED from
+ pnglibconf.h, allowing more of the decisions to be made internally
+ (pngpriv.h) during the compile. Without this, symbol prefixing is broken
+ under certain circumstances on ARM platforms. Now only the API parts of
+ the optimizations ('check' vs 'api') are exposed in the public header files
+ except that the new setting PNG_ARM_NEON_OPT documents how libpng makes the
+ decision about whether or not to use the optimizations.
+ Protect symbol prefixing against CC/CPPFLAGS/CFLAGS useage.
+ Previous iOS/Xcode fixes for the ARM NEON optimizations moved the test
+ on __ARM_NEON__ from configure time to compile time. This breaks symbol
+ prefixing because the definition of the special png_init_filter_functions
+ call was hidden at configure time if the relevant compiler arguments are
+ passed in CFLAGS as opposed to CC. This change attempts to avoid all
+ the confusion that would result by declaring the init function even when
+ it is not used, so that it will always get prefixed.
+
+Version 1.6.3beta08 [June 18, 2013]
+ Revised libpng.3 so that "doclifter" can process it.
+
+Version 1.6.3beta09 [June 27, 2013]
+ Revised example.c to illustrate use of PNG_DEFAULT_sRGB and PNG_GAMMA_MAC_18
+ as parameters for png_set_gamma(). These have been available since
+ libpng-1.5.4.
+ Renamed contrib/tools/png-fix-too-far-back.c to pngfix.c and revised it
+ to check all compressed chunks known to libpng.
+
+Version 1.6.3beta10 [July 5, 2013]
+ Updated documentation to show default behavior of benign errors correctly.
+ Only compile ARM code when PNG_READ_SUPPORTED is defined.
+ Fixed undefined behavior in contrib/tools/pngfix.c and added new strip
+ option. pngfix relied on undefined behavior and even a simple change from
+ gcc to g++ caused it to fail. The new strip option 'unsafe' has been
+ implemented and is the default if --max is given. Option names have
+ been clarified, with --strip=transform now stripping the bKGD chunk,
+ which was stripped previously with --strip=unused.
+ Added all documented chunk types to pngpriv.h
+ Unified pngfix.c source with libpng17.
+
+Version 1.6.3rc01 [July 11, 2013]
+ No changes.
+
+Version 1.6.3 [July 18, 2013]
+ Revised manual about changes in iTXt chunk handling made in libpng-1.6.0.
+ Added "/* SAFE */" comments in pngrutil.c and pngrtran.c where warnings
+ may be erroneously issued by code-checking applications.
+
+Version 1.6.4beta01 [August 21, 2013]
+ Added information about png_set_options() to the manual.
+ Delay calling png_init_filter_functions() until a row with nonzero filter
+ is found.
+
+Version 1.6.4beta02 [August 30, 2013]
+ Fixed inconsistent conditional compilation of png_chunk_unknown_handling()
+ prototype, definition, and usage. Made it depend on
+ PNG_HANDLE_AS_UNKNOWN_SUPPORTED everywhere.
+
+Version 1.6.4rc01 [September 5, 2013]
+ No changes.
+
+Version 1.6.4 [September 12, 2013]
+ No changes.
+
+Version 1.6.5 [September 14, 2013]
+ Removed two stray lines of code from arm/arm_init.c.
+
+Version 1.6.6 [September 16, 2013]
+ Removed two stray lines of code from arm/arm_init.c, again.
+
+Version 1.6.7beta01 [September 30, 2013]
+ Revised unknown chunk code to correct several bugs in the NO_SAVE_/NO_WRITE
+ combination
+ Allow HANDLE_AS_UNKNOWN to work when other options are configured off. Also
+ fixed the pngminim makefiles to work when $(MAKEFLAGS) contains stuff
+ which terminates the make options (as by default in recent versions of
+ Gentoo).
+ Avoid up-cast warnings in pngvalid.c. On ARM the alignment requirements of
+ png_modifier are greater than that of png_store and as a consequence
+ compilation of pngvalid.c results in a warning about increased alignment
+ requirements because of the bare cast to (png_modifier*). The code is safe,
+ because the pointer is known to point to a stack allocated png_modifier,
+ but this change avoids the warning.
+ Fixed default behavior of ARM_NEON_API. If the ARM NEON API option was
+ compiled without the CHECK option it defaulted to on, not off.
+ Check user callback behavior in pngunknown.c. Previous versions compiled
+ if SAVE_UNKNOWN was not available but did nothing since the callback
+ was never implemented.
+ Merged pngunknown.c with 1.7 version and back ported 1.7 improvements/fixes
+
+Version 1.6.7beta02 [October 12, 2013]
+ Made changes for compatibility with automake 1.14:
+ 1) Added the 'compile' program to the list of programs that must be cleaned
+ in autogen.sh
+ 2) Added 'subdir-objects' which causes .c files in sub-directories to be
+ compiled such that the corresponding .o files are also in the
+ sub-directory. This is because automake 1.14 warns that the
+ current behavior of compiling to the top level directory may be removed
+ in the future.
+ 3) Updated dependencies on pnglibconf.h to match the new .o locations and
+ added all the files in contrib/libtests and contrib/tools that depend
+ on pnglibconf.h
+ 4) Added 'BUILD_SOURCES = pnglibconf.h'; this is the automake recommended
+ way of handling the dependencies of sources that are machine generated;
+ unfortunately it only works if the user does 'make all' or 'make check',
+ so the dependencies (3) are still required.
+ Cleaned up (char*) casts of zlib messages. The latest version of the Intel C
+ compiler complains about casting a string literal as (char*), so copied the
+ treatment of z_const from the library code into pngfix.c
+ Simplified error message code in pngunknown. The simplification has the
+ useful side effect of avoiding a bogus warning generated by the latest
+ version of the Intel C compiler (it objects to
+ condition ? string-literal : string-literal).
+ Make autogen.sh work with automake 1.13 as well as 1.14. Do this by always
+ removing the 1.14 'compile' script but never checking for it.
+
+Version 1.6.7beta03 [October 19, 2013]
+ Added ARMv8 support (James Yu <james.yu at linaro.org>). Added file
+ arm/filter_neon_intrinsics.c; enable with -mfpu=neon.
+ Revised pngvalid to generate size images with as many filters as it can
+ manage, limited by the number of rows.
+ Cleaned up ARM NEON compilation handling. The tests are now in pngpriv.h
+ and detect the broken GCC compilers.
+
+Version 1.6.7beta04 [October 26, 2013]
+ Allow clang derived from older GCC versions to use ARM intrinsics. This
+ causes all clang builds that use -mfpu=neon to use the intrinsics code,
+ not the assembler code. This has only been tested on iOS 7. It may be
+ necessary to exclude some earlier clang versions but this seems unlikely.
+ Changed NEON implementation selection mechanism. This allows assembler
+ or intrinsics to be turned on at compile time during the build by defining
+ PNG_ARM_NEON_IMPLEMENTATION to the correct value (2 or 1). This macro
+ is undefined by default and the build type is selected in pngpriv.h.
+
+Version 1.6.7rc01 [November 2, 2013]
+ No changes.
+
+Version 1.6.7rc02 [November 7, 2013]
+ Fixed #include in filter_neon_intrinsics.c and ctype macros. The ctype char
+ checking macros take an unsigned char argument, not a signed char.
+
+Version 1.6.7 [November 14, 2013]
+ No changes.
+
+Version 1.6.8beta01 [November 24, 2013]
+ Moved prototype for png_handle_unknown() in pngpriv.h outside of
+ the #ifdef PNG_SET_UNKNOWN_CHUNKS_SUPPORTED/#endif block.
+ Added "-Wall" to CFLAGS in contrib/pngminim/*/makefile
+ Conditionally compile some unused functions reported by -Wall in
+ pngminim.
+ Fixed 'minimal' builds. Various obviously useful minimal configurations
+ don't build because of missing contrib/libtests test programs and
+ overly complex dependencies in scripts/pnglibconf.dfa. This change
+ adds contrib/conftest/*.dfa files that can be used in automatic build
+ scripts to ensure that these configurations continue to build.
+ Enabled WRITE_INVERT and WRITE_PACK in contrib/pngminim/encoder.
+ Fixed pngvalid 'fail' function declaration on the Intel C Compiler.
+ This reverts to the previous 'static' implementation and works round
+ the 'unused static function' warning by using PNG_UNUSED().
+
+Version 1.6.8beta02 [November 30, 2013]
+ Removed or marked PNG_UNUSED some harmless "dead assignments" reported
+ by clang scan-build.
+ Changed tabs to 3 spaces in png_debug macros and changed '"%s"m'
+ to '"%s" m' to improve portability among compilers.
+ Changed png_free_default() to free() in pngtest.c
+
+Version 1.6.8rc01 [December 12, 2013]
+ Tidied up pngfix inits and fixed pngtest no-write builds.
+
+Version 1.6.8rc02 [December 14, 2013]
+ Handle zero-length PLTE chunk or NULL palette with png_error()
+ instead of png_chunk_report(), which by default issues a warning
+ rather than an error, leading to later reading from a NULL pointer
+ (png_ptr->palette) in png_do_expand_palette(). This is CVE-2013-6954
+ and VU#650142. Libpng-1.6.1 through 1.6.7 are vulnerable.
+ Libpng-1.6.0 and earlier do not have this bug.
+
+Version 1.6.8 [December 19, 2013]
+ No changes.
+
+Version 1.6.9beta01 [December 26, 2013]
+ Bookkeeping: Moved functions around (no changes). Moved transform
+ function definitions before the place where they are called so that
+ they can be made static. Move the intrapixel functions and the
+ grayscale palette builder out of the png?tran.c files. The latter
+ isn't a transform function and is no longer used internally, and the
+ former MNG specific functions are better placed in pngread/pngwrite.c
+ Made transform implementation functions static. This makes the internal
+ functions called by png_do_{read|write}_transformations static. On an
+ x86-64 DLL build (Gentoo Linux) this reduces the size of the text
+ segment of the DLL by 1208 bytes, about 0.6%. It also simplifies
+ maintenance by removing the declarations from pngpriv.h and allowing
+ easier changes to the internal interfaces.
+ Rebuilt configure scripts with automake-1.14.1 and autoconf-2.69
+ in the tar distributions.
+
+Version 1.6.9beta02 [January 1, 2014]
+ Added checks for libpng 1.5 to pngvalid.c. This supports the use of
+ this version of pngvalid in libpng 1.5
+ Merged with pngvalid.c from libpng-1.7 changes to create a single
+ pngvalid.c
+ Removed #error macro from contrib/tools/pngfix.c (Thomas Klausner).
+ Merged pngrio.c, pngtrans.c, pngwio.c, and pngerror.c with libpng-1.7.0
+ Merged libpng-1.7.0 changes to make no-interlace configurations work
+ with test programs.
+ Revised pngvalid.c to support libpng 1.5, which does not support the
+ PNG_MAXIMUM_INFLATE_WINDOW option, so #define it out when appropriate in
+ pngvalid.c
+ Allow unversioned links created on install to be disabled in configure.
+ In configure builds 'make install' changes/adds links like png.h
+ and libpng.a to point to the newly installed, versioned, files (e.g.
+ libpng17/png.h and libpng17.a). Three new configure options and some
+ rearrangement of Makefile.am allow creation of these links to be disabled.
+
+Version 1.6.9beta03 [January 10, 2014]
+ Removed potentially misleading warning from png_check_IHDR().
+
+Version 1.6.9beta04 [January 20, 2014]
+ Updated scripts/makefile.* to use CPPFLAGS (Cosmin).
+ Added clang attribute support (Cosmin).
+
+Version 1.6.9rc01 [January 28, 2014]
+ No changes.
+
+Version 1.6.9rc02 [January 30, 2014]
+ Quiet an uninitialized memory warning from VC2013 in png_get_png().
+
+Version 1.6.9 [February 6, 2014]
+
+Version 1.6.10beta01 [February 9, 2014]
+ Backported changes from libpng-1.7.0beta30 and beta31:
+ Fixed a large number of instances where PNGCBAPI was omitted from
+ function definitions.
+ Added pngimage test program for png_read_png() and png_write_png()
+ with two new test scripts.
+ Removed dependence on !PNG_READ_EXPAND_SUPPORTED for calling
+ png_set_packing() in png_read_png().
+ Fixed combination of ~alpha with shift. On read invert alpha, processing
+ occurred after shift processing, which causes the final values to be
+ outside the range that should be produced by the shift. Reversing the
+ order on read makes the two transforms work together correctly and mirrors
+ the order used on write.
+ Do not read invalid sBIT chunks. Previously libpng only checked sBIT
+ values on write, so a malicious PNG writer could therefore cause
+ the read code to return an invalid sBIT chunk, which might lead to
+ application errors or crashes. Such chunks are now skipped (with
+ chunk_benign_error).
+ Make png_read_png() and png_write_png() prototypes in png.h depend
+ upon PNG_READ_SUPPORTED and PNG_WRITE_SUPPORTED.
+ Support builds with unsupported PNG_TRANSFORM_* values. All of the
+ PNG_TRANSFORM_* values are always defined in png.h and, because they
+ are used for both read and write in some cases, it is not reliable
+ to #if out ones that are totally unsupported. This change adds error
+ detection in png_read_image() and png_write_image() to do a
+ png_app_error() if the app requests something that cannot be done
+ and it adds corresponding code to pngimage.c to handle such options
+ by not attempting to test them.
+
+Version 1.6.10beta02 [February 23, 2014]
+ Moved redefines of png_error(), png_warning(), png_chunk_error(),
+ and png_chunk_warning() from pngpriv.h to png.h to make them visible
+ to libpng-calling applications.
+ Moved OS dependent code from arm/arm_init.c, to allow the included
+ implementation of the ARM NEON discovery function to be set at
+ build-time and provide sample implementations from the current code in the
+ contrib/arm-neon subdirectory. The __linux__ code has also been changed to
+ compile and link on Android by using /proc/cpuinfo, and the old linux code
+ is in contrib/arm-neon/linux-auxv.c. The new code avoids POSIX and Linux
+ dependencies apart from opening /proc/cpuinfo and is C90 compliant.
+ Check for info_ptr == NULL early in png_read_end() so we don't need to
+ run all the png_handle_*() and depend on them to return if info_ptr == NULL.
+ This improves the performance of png_read_end(png_ptr, NULL) and makes
+ it more robust against future programming errors.
+ Check for __has_extension before using it in pngconf.h, to
+ support older Clang versions (Jeremy Sequoia).
+ Treat CRC error handling with png_set_crc_action(), instead of with
+ png_set_benign_errors(), which has been the case since libpng-1.6.0beta18.
+ Use a user warning handler in contrib/gregbook/readpng2.c instead of default,
+ so warnings will be put on stderr even if libpng has CONSOLE_IO disabled.
+ Added png_ptr->process_mode = PNG_READ_IDAT_MODE in png_push_read_chunk
+ after recognizing the IDAT chunk, which avoids an infinite loop while
+ reading a datastream whose first IDAT chunk is of zero-length.
+ This fixes CERT VU#684412 and CVE-2014-0333.
+ Don't recognize known sRGB profiles as sRGB if they have been hacked,
+ but don't reject them and don't issue a copyright violation warning.
+
+Version 1.6.10beta03 [February 25, 2014]
+ Moved some documentation from png.h to libpng.3 and libpng-manual.txt
+ Minor editing of contrib/arm-neon/README and contrib/examples/*.c
+
+Version 1.6.10rc01 [February 27, 2014]
+ Fixed typos in the manual and in scripts/pnglibconf.dfa (CFLAGS -> CPPFLAGS
+ and PNG_USR_CONFIG -> PNG_USER_CONFIG).
+
+Version 1.6.10rc02 [February 28, 2014]
+ Removed unreachable return statement after png_chunk_error()
+ in pngrutil.c
+
+Version 1.6.10rc03 [March 4, 2014]
+ Un-deprecated png_data_freer().
+
+Version 1.6.10 [March 6, 2014]
+ No changes.
+
+Version 1.6.11beta01 [March 17, 2014]
+ Use "if (value != 0)" instead of "if (value)" consistently.
+ Changed ZlibSrcDir from 1.2.5 to 1.2.8 in projects/vstudio.
+ Moved configuration information from the manual to the INSTALL file.
+
+Version 1.6.11beta02 [April 6, 2014]
+ Removed #if/#else/#endif from inside two pow() calls in pngvalid.c because
+ they were handled improperly by Portland Group's PGI-14.1 - PGI-14.3
+ when using its "__builtin_pow()" function.
+ Silence 'unused parameter' build warnings (Cosmin Truta).
+ $(CP) is now used alongside $(RM_F). Also, use 'copy' instead of 'cp'
+ where applicable, and applied other minor makefile changes (Cosmin).
+ Don't warn about invalid dimensions exceeding user limits (Cosmin).
+ Allow an easy replacement of the default pre-built configuration
+ header with a custom header, via the make PNGLIBCONF_H_PREBUILT
+ macro (Cosmin).
+
+Version 1.6.11beta03 [April 6, 2014]
+ Fixed a typo in pngrutil.c, introduced in libpng-1.5.6, that interferes
+ with "blocky" expansion of sub-8-bit interlaced PNG files (Eric Huss).
+ Optionally use __builtin_bswap16() in png_do_swap().
+
+Version 1.6.11beta04 [April 19, 2014]
+ Made progressive reading of interlaced images consistent with the
+ behavior of the sequential reader and consistent with the manual, by
+ moving some code out of the PNG_READ_INTERLACING_SUPPORTED blocks. The
+ row_callback now receives the proper pass number and unexpanded rows, when
+ png_combine_row() isn't built or used, and png_set_interlace_handling()
+ is not called.
+ Allow PNG_sRGB_PROFILE_CHECKING = (-1) to mean no sRGB profile checking.
+
+Version 1.6.11beta05 [April 26, 2014]
+ Do not reject ICC V2 profiles that lack padding (Kai-Uwe Behrmann).
+ Relocated closing bracket of the sRGB profile test loop to avoid getting
+ "Not recognizing known sRGB profile that has been edited" warning for
+ ICC V2 profiles that lack the MD5 signature in the profile header.
+
+Version 1.6.11beta06 [May 19, 2014]
+ Added PNG_SKIP_sRGB_CHECK_PROFILE choice for png_set_option().
+
+Version 1.6.11rc01 [May 27, 2014]
+ No changes.
+
+Version 1.6.11rc02 [June 3, 2014]
+ Test ZLIB_VERNUM instead of PNG_ZLIB_VERNUM in contrib/tools/pngfix.c
+
+Version 1.6.11 [June 5, 2014]
+ No changes.
+
+Version 1.6.12rc01 [June 6, 2014]
+ Relocated new code from 1.6.11beta06 in png.c to a point after the
+ declarations (Max Stepin).
+
+Version 1.6.12rc02 [June 7, 2014]
+ Changed file permissions of contrib/tools/intgamma.sh,
+ test-driver, and compile from 0644 to 0755 (Cosmin).
+
+Version 1.6.12rc03 [June 8, 2014]
+ Ensure "__has_attribute()" macro exists before trying to use it with
+ old clang compilers (MacPorts Ticket #43939).
+
+Version 1.6.12 [June 12, 2014]
+ No changes.
+
+Version 1.6.13beta01 [July 4, 2014]
+ Quieted -Wsign-compare and -Wclobber compiler warnings in
+ contrib/pngminus/*.c
+ Added "(void) png_ptr;" where needed in contrib/gregbook to quiet
+ compiler complaints about unused pointers.
+ Split a long output string in contrib/gregbook/rpng2-x.c.
+ Added "PNG_SET_OPTION" requirement for sRGB chunk support to pnglibconf.dfa,
+ Needed for write-only support (John Bowler).
+ Changed "if defined(__ARM_NEON__)" to
+ "if (defined(__ARM_NEON__) || defined(__ARM_NEON))" (James Wu).
+ Fixed clang no-warning builds: png_digit was defined but never used.
+
+Version 1.6.13beta02 [July 21, 2014]
+ Fixed an incorrect separator ("/" should be "\") in scripts/makefile.vcwin32
+ (bug report from Wolfgang S. Kechel). Bug was introduced in libpng-1.6.11.
+ Also fixed makefile.bc32, makefile.bor, makefile.msc, makefile.intel, and
+ makefile.tc3 similarly.
+
+Version 1.6.13beta03 [August 3, 2014]
+ Removed scripts/makefile.elf. It has not worked since libpng-1.5.0beta14
+ due to elimination of the PNG_FUNCTION_EXPORT and PNG_DATA_EXPORT
+ definitions from pngconf.h.
+ Ensure that CMakeLists.txt makes the target "lib" directory before making
+ symbolic link into it (SourceForge bug report #226 by Rolf Timmermans).
+
+Version 1.6.13beta04 [August 8, 2014]
+ Added opinion that the ECCN (Export Control Classification Number) for
+ libpng is EAR99 to the README file.
+ Eliminated use of "$<" in makefile explicit rules, when copying
+ $PNGLIBCONF_H_PREBUILT. This does not work on some versions of make;
+ bug introduced in libpng version 1.6.11.
+
+Version 1.6.13rc01 [August 14, 2014]
+ Made "ccopts" agree with "CFLAGS" in scripts/makefile.hp* and makefile.*sunu
+
+Version 1.6.13 [August 21, 2014]
+ No changes.
+
+Version 1.6.14beta01 [September 14, 2014]
+ Guard usage of png_ptr->options with #ifdef PNG_SET_OPTION_SUPPORTED.
+ Do not build contrib/tools/pngfix.c when PNG_SETJMP_NOT_SUPPORTED,
+ to allow "make" to complete without setjmp support (bug report by
+ Claudio Fontana)
+ Add "#include <setjmp.h>" to contrib/tools/pngfix.c (John Bowler)
+
+Version 1.6.14beta02 [September 18, 2014]
+ Use nanosleep() instead of usleep() in contrib/gregbook/rpng2-x.c
+ because usleep() is deprecated.
+ Define usleep() in contrib/gregbook/rpng2-x.c if not already defined
+ in unistd.h and nanosleep() is not available; fixes error introduced
+ in libpng-1.6.13.
+ Disable floating point exception handling in pngvalid.c when
+ PNG_FLOATING_ARITHMETIC is not supported (bug report by "zootus
+ at users.sourceforge.net").
+
+Version 1.6.14beta03 [September 19, 2014]
+ Define FE_DIVBYZERO, FE_INVALID, and FE_OVERFLOW in pngvalid.c if not
+ already defined. Revert floating point exception handling in pngvalid.c
+ to version 1.6.14beta01 behavior.
+
+Version 1.6.14beta04 [September 27, 2014]
+ Fixed incorrect handling of the iTXt compression flag in pngrutil.c
+ (bug report by Shunsaku Hirata). Bug was introduced in libpng-1.6.0.
+
+Version 1.6.14beta05 [October 1, 2014]
+ Added "option READ_iCCP enables READ_COMPRESSED_TEXT" to pnglibconf.dfa
+
+Version 1.6.14beta06 [October 5, 2014]
+ Removed unused "text_len" parameter from private function png_write_zTXt().
+ Conditionally compile some code in png_deflate_claim(), when
+ PNG_WARNINGS_SUPPORTED and PNG_ERROR_TEXT_SUPPORTED are disabled.
+ Replaced repeated code in pngpread.c with PNG_PUSH_SAVE_BUFFER_IF_FULL.
+ Added "chunk iTXt enables TEXT" and "chunk zTXt enables TEXT"
+ to pnglibconf.dfa.
+ Removed "option READ_COMPRESSED_TEXT enables READ_TEXT" from pnglibconf.dfa,
+ to make it possible to configure a libpng that supports iCCP but not TEXT.
+
+Version 1.6.14beta07 [October 7, 2014]
+ Removed "option WRITE_COMPRESSED_TEXT enables WRITE_TEXT" from pnglibconf.dfa
+ Only mark text chunks as written after successfully writing them.
+
+Version 1.6.14rc01 [October 15, 2014]
+ Fixed some typos in comments.
+
+Version 1.6.14rc02 [October 17, 2014]
+ Changed png_convert_to_rfc_1123() to png_convert_to_rfc_1123_buffer()
+ in the manual, to reflect the change made in libpng-1.6.0.
+ Updated README file to explain that direct access to the png_struct
+ and info_struct members has not been permitted since libpng-1.5.0.
+
+Version 1.6.14 [October 23, 2014]
No changes.
-Version 1.5.13 [September 27, 2012]
+Version 1.6.15beta01 [October 29, 2014]
+ Changed "if (!x)" to "if (x == 0)" and "if (x)" to "if (x != 0)"
+ Simplified png_free_data().
+ Added missing "ptr = NULL" after some instances of png_free().
+
+Version 1.6.15beta02 [November 1, 2014]
+ Changed remaining "if (!x)" to "if (x == 0)" and "if (x)" to "if (x != 0)"
+
+Version 1.6.15beta03 [November 3, 2014]
+ Added PNG_USE_ARM_NEON configuration flag (Marcin Juszkiewicz).
+
+Version 1.6.15beta04 [November 4, 2014]
+ Removed new PNG_USE_ARM_NEON configuration flag and made a one-line
+ revision to configure.ac to support ARM on aarch64 instead (John Bowler).
+
+Version 1.6.15beta05 [November 5, 2014]
+ Use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING in
+ example.c, pngtest.c, and applications in the contrib directory.
+ Avoid out-of-bounds memory access in png_user_version_check().
+ Simplified and future-proofed png_user_version_check().
+ Fixed GCC unsigned int->float warnings. Various versions of GCC
+ seem to generate warnings when an unsigned value is implicitly
+ converted to double. This is probably a GCC bug but this change
+ avoids the issue by explicitly converting to (int) where safe.
+ Free all allocated memory in pngimage. The file buffer cache was left
+ allocated at the end of the program, harmless but it causes memory
+ leak reports from clang.
+ Fixed array size calculations to avoid warnings. At various points
+ in the code the number of elements in an array is calculated using
+ sizeof. This generates a compile time constant of type (size_t) which
+ is then typically assigned to an (unsigned int) or (int). Some versions
+ of GCC on 64-bit systems warn about the apparent narrowing, even though
+ the same compiler does apparently generate the correct, in-range,
+ numeric constant. This adds appropriate, safe, casts to make the
+ warnings go away.
+
+Version 1.6.15beta06 [November 6, 2014]
+ Reverted use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING
+ in the manual, example.c, pngtest.c, and applications in the contrib
+ directory. It was incorrect advice.
+
+Version 1.6.15beta07 [November 7, 2014]
+ Removed #ifdef PNG_16BIT_SUPPORTED/#endif around png_product2(); it is
+ needed by png_reciprocal2().
+ Added #ifdef PNG_16BIT_SUPPORTED/#endif around png_log16bit() and
+ png_do_swap().
+ Changed all "#endif /* PNG_FEATURE_SUPPORTED */" to "#endif /* FEATURE */"
+
+Version 1.6.15beta08 [November 8, 2014]
+ More housecleaning in *.h
+
+Version 1.6.15rc01 [November 13, 2014]
+
+Version 1.6.15rc02 [November 14, 2014]
+ The macros passed in the command line to Borland make were ignored if
+ similarly-named macros were already defined in makefiles. This behavior
+ is different from POSIX make and other make programs. Surround the
+ macro definitions with ifndef guards (Cosmin).
+
+Version 1.6.15rc03 [November 16, 2014]
+ Added "-D_CRT_SECURE_NO_WARNINGS" to CFLAGS in scripts/makefile.vcwin32.
+ Removed the obsolete $ARCH variable from scripts/makefile.darwin.
+
+Version 1.6.15 [November 20, 2014]
+ No changes.
+
+Version 1.6.16beta01 [December 14, 2014]
+ Added ".align 2" to arm/filter_neon.S to support old GAS assemblers that
+ don't do alignment correctly.
+ Revised Makefile.am and scripts/symbols.dfn to work with MinGW/MSYS
+ (Bob Friesenhahn).
+
+Version 1.6.16beta02 [December 15, 2014]
+ Revised Makefile.am and scripts/*.dfn again to work with MinGW/MSYS;
+ renamed scripts/*.dfn to scripts/*.c (John Bowler).
+
+Version 1.6.16beta03 [December 21, 2014]
+ Quiet a "comparison always true" warning in pngstest.c (John Bowler).
+
+Version 1.6.16rc01 [December 21, 2014]
+ Restored a test on width that was removed from png.c at libpng-1.6.9
+ (Bug report by Alex Eubanks).
+
+Version 1.6.16rc02 [December 21, 2014]
+ Undid the update to pngrutil.c in 1.6.16rc01.
+
+Version 1.6.16rc03 [December 21, 2014]
+ Fixed an overflow in png_combine_row with very wide interlaced images.
+
+Version 1.6.16 [December 22, 2014]
No changes.

+VIII. Configuring libpng for 16-bit platforms
+
+You will want to look into zconf.h to tell zlib (and thus libpng) that
+it cannot allocate more then 64K at a time. Even if you can, the memory
+won't be accessible. So limit zlib and libpng to 64K by defining MAXSEG_64K.
+
+IX. Configuring for DOS
+
+For DOS users who only have access to the lower 640K, you will
+have to limit zlib's memory usage via a png_set_compression_mem_level()
+call. See zlib.h or zconf.h in the zlib library for more information.
+
+X. Configuring for Medium Model
+
+Libpng's support for medium model has been tested on most of the popular
+compilers. Make sure MAXSEG_64K gets defined, USE_FAR_KEYWORD gets
+defined, and FAR gets defined to far in pngconf.h, and you should be
+all set. Everything in the library (except for zlib's structure) is
+expecting far data. You must use the typedefs with the p or pp on
+the end for pointers (or at least look at them and be careful). Make
+note that the rows of data are defined as png_bytepp, which is
+an "unsigned char far * far *".
+
+XI. Prepending a prefix to exported symbols
+
+Starting with libpng-1.6.0, you can configure libpng (when using the
+"configure" script) to prefix all exported symbols by means of the
+configuration option "--with-libpng-prefix=FOO_", where FOO_ can be any
+string beginning with a letter and containing only uppercase
+and lowercase letters, digits, and the underscore (i.e., a C language
+identifier). This creates a set of macros in pnglibconf.h, so this is
+transparent to applications; their function calls get transformed by
+the macros to use the modified names.
+
+XII. Configuring for compiler xxx:
+
+All includes for libpng are in pngconf.h. If you need to add, change
+or delete an include, this is the place to do it.
+The includes that are not needed outside libpng are placed in pngpriv.h,
+which is only used by the routines inside libpng itself.
+The files in libpng proper only include pngpriv.h and png.h, which
+in turn includes pngconf.h and, as of libpng-1.5.0, pnglibconf.h.
+As of libpng-1.5.0, pngpriv.h also includes three other private header
+files, pngstruct.h, pnginfo.h, and pngdebug.h, which contain material
+that previously appeared in the public headers.
+
+XIII. Removing unwanted object code
+
+There are a bunch of #define's in pngconf.h that control what parts of
+libpng are compiled. All the defines end in _SUPPORTED. If you are
+never going to use a capability, you can change the #define to #undef
+before recompiling libpng and save yourself code and data space, or
+you can turn off individual capabilities with defines that begin with
+PNG_NO_.
+
+In libpng-1.5.0 and later, the #define's are in pnglibconf.h instead.
+
+You can also turn all of the transforms and ancillary chunk capabilities
+off en masse with compiler directives that define
+PNG_NO_READ[or WRITE]_TRANSFORMS, or PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS,
+or all four, along with directives to turn on any of the capabilities that
+you do want. The PNG_NO_READ[or WRITE]_TRANSFORMS directives disable the
+extra transformations but still leave the library fully capable of reading
+and writing PNG files with all known public chunks. Use of the
+PNG_NO_READ[or WRITE]_ANCILLARY_CHUNKS directive produces a library
+that is incapable of reading or writing ancillary chunks. If you are
+not using the progressive reading capability, you can turn that off
+with PNG_NO_PROGRESSIVE_READ (don't confuse this with the INTERLACING
+capability, which you'll still have).
+
+All the reading and writing specific code are in separate files, so the
+linker should only grab the files it needs. However, if you want to
+make sure, or if you are building a stand alone library, all the
+reading files start with "pngr" and all the writing files start with "pngw".
+The files that don't match either (like png.c, pngtrans.c, etc.)
+are used for both reading and writing, and always need to be included.
+The progressive reader is in pngpread.c
+
+If you are creating or distributing a dynamically linked library (a .so
+or DLL file), you should not remove or disable any parts of the library,
+as this will cause applications linked with different versions of the
+library to fail if they call functions not available in your library.
+The size of the library itself should not be an issue, because only
+those sections that are actually used will be loaded into memory.
+
+XIV. Changes to the build and configuration of libpng in libpng-1.5.x
+
+Details of internal changes to the library code can be found in the CHANGES
+file and in the GIT repository logs. These will be of no concern to the vast
+majority of library users or builders; however, the few who configure libpng
+to a non-default feature set may need to change how this is done.
+
+There should be no need for library builders to alter build scripts if
+these use the distributed build support - configure or the makefiles -
+however, users of the makefiles may care to update their build scripts
+to build pnglibconf.h where the corresponding makefile does not do so.
+
+Building libpng with a non-default configuration has changed completely.
+The old method using pngusr.h should still work correctly even though the
+way pngusr.h is used in the build has been changed; however, library
+builders will probably want to examine the changes to take advantage of
+new capabilities and to simplify their build system.
+
+A. Specific changes to library configuration capabilities
+
+The exact mechanism used to control attributes of API functions has
+changed. A single set of operating system independent macro definitions
+is used and operating system specific directives are defined in
+pnglibconf.h
+
+As part of this the mechanism used to choose procedure call standards on
+those systems that allow a choice has been changed. At present this only
+affects certain Microsoft (DOS, Windows) and IBM (OS/2) operating systems
+running on Intel processors. As before, PNGAPI is defined where required
+to control the exported API functions; however, two new macros, PNGCBAPI
+and PNGCAPI, are used instead for callback functions (PNGCBAPI) and
+(PNGCAPI) for functions that must match a C library prototype (currently
+only png_longjmp_ptr, which must match the C longjmp function.) The new
+approach is documented in pngconf.h
+
+Despite these changes, libpng 1.5.0 only supports the native C function
+calling standard on those platforms tested so far (__cdecl on Microsoft
+Windows). This is because the support requirements for alternative
+calling conventions seem to no longer exist. Developers who find it
+necessary to set PNG_API_RULE to 1 should advise the mailing list
+(png-mng-implement) of this and library builders who use Openwatcom and
+therefore set PNG_API_RULE to 2 should also contact the mailing list.
+
+B. Changes to the configuration mechanism
+
+Prior to libpng-1.5.0 library builders who needed to configure libpng
+had either to modify the exported pngconf.h header file to add system
+specific configuration or had to write feature selection macros into
+pngusr.h and cause this to be included into pngconf.h by defining
+PNG_USER_CONFIG. The latter mechanism had the disadvantage that an
+application built without PNG_USER_CONFIG defined would see the
+unmodified, default, libpng API and thus would probably fail to link.
+
+These mechanisms still work in the configure build and in any makefile
+build that builds pnglibconf.h, although the feature selection macros
+have changed somewhat as described above. In 1.5.0, however, pngusr.h is
+processed only once, at the time the exported header file pnglibconf.h is
+built. pngconf.h no longer includes pngusr.h; therefore, pngusr.h is ignored
+after the build of pnglibconf.h and it is never included in an application
+build.
+
+The formerly used alternative of adding a list of feature macros to the
+CPPFLAGS setting in the build also still works; however, the macros will be
+copied to pnglibconf.h and this may produce macro redefinition warnings
+when the individual C files are compiled.
+
+All configuration now only works if pnglibconf.h is built from
+scripts/pnglibconf.dfa. This requires the program awk. Brian Kernighan
+(the original author of awk) maintains C source code of that awk and this
+and all known later implementations (often called by subtly different
+names - nawk and gawk for example) are adequate to build pnglibconf.h.
+The Sun Microsystems (now Oracle) program 'awk' is an earlier version
+and does not work; this may also apply to other systems that have a
+functioning awk called 'nawk'.
+
+Configuration options are now documented in scripts/pnglibconf.dfa. This
+file also includes dependency information that ensures a configuration is
+consistent; that is, if a feature is switched off, dependent features are
+also switched off. As a recommended alternative to using feature macros in
+pngusr.h a system builder may also define equivalent options in pngusr.dfa
+(or, indeed, any file) and add that to the configuration by setting
+DFA_XTRA to the file name. The makefiles in contrib/pngminim illustrate
+how to do this, and also illustrate a case where pngusr.h is still required.
+
+After you have built libpng, the definitions that were recorded in
+pnglibconf.h are available to your application (pnglibconf.h is included
+in png.h and gets installed alongside png.h and pngconf.h in your
+$PREFIX/include directory). Do not edit pnglibconf.h after you have built
+libpng, because than the settings would not accurately reflect the settings
+that were used to build libpng.
+
+XV. Configuring libpng for multiprocessing
+
+Libpng uses setjmp()/longjmp() for error handling. Unfortunately setjmp()
+is known to be not thread-safe on some platforms and we don't know of
+any platform where it is guaranteed to be thread-safe. Therefore, if
+your application is going to be using multiple threads, you should
+configure libpng with PNG_NO_SETJMP in your pngusr.dfa file, with
+-DPNG_NO_SETJMP on your compile line, or with
+
+ #undef PNG_SETJMP_SUPPORTED
+
+in your pnglibconf.h or pngusr.h.
+
+XVI. Other sources of information about libpng:

Further information can be found in the README and libpng-manual.txt
files, in the individual makefiles, in png.h, and the manual pages

+ * ask for the image data to be presented in a number of different formats. You
+ * do this by simply changing the 'format' parameter set before allocating the
+ * buffer.
+ *
+ * The format parameter consists of five flags that define various aspects of
+ * the image, you can simply add these together to get the format or you can use
+ * one of the predefined macros from png.h (as above):
+ *
+ * PNG_FORMAT_FLAG_COLOR: if set the image will have three color components per
+ * pixel (red, green and blue), if not set the image will just have one
+ * luminance (grayscale) component.
+ *
+ * PNG_FORMAT_FLAG_ALPHA: if set each pixel in the image will have an additional
+ * alpha value; a linear value that describes the degree the image pixel
+ * covers (overwrites) the contents of the existing pixel on the display.
+ *
+ * PNG_FORMAT_FLAG_LINEAR: if set the components of each pixel will be returned
+ * as a series of 16-bit linear values, if not set the components will be
+ * returned as a series of 8-bit values encoded according to the 'sRGB'
+ * standard. The 8-bit format is the normal format for images intended for
+ * direct display, because almost all display devices do the inverse of the
+ * sRGB transformation to the data they receive. The 16-bit format is more
+ * common for scientific data and image data that must be further processed;
+ * because it is linear simple math can be done on the component values.
+ * Regardless of the setting of this flag the alpha channel is always linear,
+ * although it will be 8 bits or 16 bits wide as specified by the flag.
+ *
+ * PNG_FORMAT_FLAG_BGR: if set the components of a color pixel will be returned
+ * in the order blue, then green, then red. If not set the pixel components
+ * are in the order red, then green, then blue.
+ *
+ * PNG_FORMAT_FLAG_AFIRST: if set the alpha channel (if present) precedes the
+ * color or grayscale components. If not set the alpha channel follows the
+ * components.
+ *
+ * You do not have to read directly from a file. You can read from memory or,
+ * on systems that support it, from a <stdio.h> FILE*. This is controlled by
+ * the particular png_image_read_from_ function you call at the start. Likewise
+ * on write you can write to a FILE* if your system supports it. Check the
+ * macro PNG_STDIO_SUPPORTED to see if stdio support has been included in your
+ * libpng build.
+ *
+ * If you read 16-bit (PNG_FORMAT_FLAG_LINEAR) data you may need to write it in
+ * the 8-bit format for display. You do this by setting the convert_to_8bit
+ * flag to 'true'.
+ *
+ * Don't repeatedly convert between the 8-bit and 16-bit forms. There is
+ * significant data loss when 16-bit data is converted to the 8-bit encoding and
+ * the current libpng implementation of conversion to 16-bit is also

+values further because this avoids the need to decode and re-encode each
component value whenever arithmetic is performed. A lot of graphics software
uses linear values for this reason, often with higher precision component values
to preserve overall accuracy.
+
+The output_gamma value expresses how to decode the output values, not how
+they are encoded. The values used correspond to the normal numbers used to
+describe the overall gamma of a computer display system; for example 2.2 for
+an sRGB conformant system. The values are scaled by 100000 in the _fixed
+version of the API (so 220000 for sRGB.)
+
+The inverse of the value is always used to provide a default for the PNG file
+encoding if it has no gAMA chunk and if png_set_gamma() has not been called
+to override the PNG gamma information.
+
+When the ALPHA_OPTIMIZED mode is selected the output gamma is used to encode
+opaque pixels however pixels with lower alpha values are not encoded,
+regardless of the output gamma setting.
+
+When the standard Porter Duff handling is requested with mode 1 the output
+encoding is set to be linear and the output_gamma value is only relevant
+as a default for input data that has no gamma information. The linear output
+encoding will be overridden if png_set_gamma() is called - the results may be
+highly unexpected!
+
+The following numbers are derived from the sRGB standard and the research
+behind it. sRGB is defined to be approximated by a PNG gAMA chunk value of
+0.45455 (1/2.2) for PNG. The value implicitly includes any viewing
+correction required to take account of any differences in the color
+environment of the original scene and the intended display environment; the
+value expresses how to *decode* the image for display, not how the original
+data was *encoded*.
+
+sRGB provides a peg for the PNG standard by defining a viewing environment.
+sRGB itself, and earlier TV standards, actually use a more complex transform
+(a linear portion then a gamma 2.4 power law) than PNG can express. (PNG is
+limited to simple power laws.) By saying that an image for direct display on
+an sRGB conformant system should be stored with a gAMA chunk value of 45455
+(11.3.3.2 and 11.3.3.5 of the ISO PNG specification) the PNG specification
+makes it possible to derive values for other display systems and
+environments.
+
+The Mac value is deduced from the sRGB based on an assumption that the actual
+extra viewing correction used in early Mac display systems was implemented as
+a power 1.45 lookup table.
+
+Any system where a programmable lookup table is used or where the behavior of
+the final display device characteristics can be changed requires system
+specific code to obtain the current characteristic. However this can be
+difficult and most PNG gamma correction only requires an approximate value.
+
+By default, if png_set_alpha_mode() is not called, libpng assumes that all
+values are unencoded, linear, values and that the output device also has a
+linear characteristic. This is only very rarely correct - it is invariably
+better to call png_set_alpha_mode() with PNG_DEFAULT_sRGB than rely on the
+default if you don't know what the right answer is!
+
+The special value PNG_GAMMA_MAC_18 indicates an older Mac system (pre Mac OS
+10.6) which used a correction table to implement a somewhat lower gamma on an
+otherwise sRGB system.
+
+Both these values are reserved (not simple gamma values) in order to allow
+more precise correction internally in the future.

+NOTE: the values can be passed to either the fixed or floating

+
+This is the classic Jim Blinn approach and will work in academic

+
+ png_set_expand_16(pp);
+ png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_DEFAULT_sRGB);
+
+This is a somewhat more realistic Jim Blinn inspired approach. PNG files
+are assumed to have the sRGB encoding if not marked with a gamma value and
+the output is always 16 bits per component. This permits accurate scaling
+and processing of the data. If you know that your input PNG files were
+generated locally you might need to replace PNG_DEFAULT_sRGB with the
+correct value for your system.
+
+ png_set_alpha_mode(pp, PNG_ALPHA_OPTIMIZED, PNG_DEFAULT_sRGB);
+
+If you just need to composite the PNG image onto an existing background
+and if you control the code that does this you can use the optimization
+setting. In this case you just copy completely opaque pixels to the
+output. For pixels that are not completely transparent (you just skip
+those) you do the composition math using png_composite or png_composite_16
+below then encode the resultant 8-bit or 16-bit values to match the output

+
+ Other cases
+
+If neither the PNG nor the standard linear encoding work for you because
+of the software or hardware you use then you have a big problem. The PNG
+case will probably result in halos around the image. The linear encoding
+will probably result in a washed out, too bright, image (it's actually too
+contrasty.) Try the ALPHA_OPTIMIZED mode above - this will probably
+substantially reduce the halos. Alternatively try:
+
+ png_set_alpha_mode(pp, PNG_ALPHA_BROKEN, PNG_DEFAULT_sRGB);
+
+This option will also reduce the halos, but there will be slight dark
+halos round the opaque parts of the image where the background is light.
+In the OPTIMIZED mode the halos will be light halos where the background
+is dark. Take your pick - the halos are unavoidable unless you can get
+your hardware/software fixed! (The OPTIMIZED approach is slightly

+When the default gamma of PNG files doesn't match the output gamma.

+matching value. If you know your PNG files have a gamma that doesn't
+match the output you can take advantage of the fact that
+png_set_alpha_mode always sets the output gamma but only sets the PNG
+default if it is not already set:
+
+ png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
+ png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
+
+The first call sets both the default and the output gamma values, the
+second call overrides the output gamma without changing the default. This
+is easier than achieving the same effect with png_set_gamma. You must use

+sophisticated APIs above - these support a wide variety of in-memory formats
+and a wide variety of sophisticated transformations to those formats as well
+as a wide variety of APIs to manipulate ancilliary information.
+
+To read a PNG file using the simplified API:
+
+ 1) Declare a 'png_image' structure (see below) on the
+ stack and memset() it to all zero.
+
+ 2) Call the appropriate png_image_begin_read... function.
+
+ 3) Set the png_image 'format' member to the required
+ format and allocate a buffer for the image.
+
+ 4) Call png_image_finish_read to read the image into
+ your buffer.
+
+There are no restrictions on the format of the PNG input itself; all valid
+color types, bit depths, and interlace methods are acceptable, and the
+input image is transformed as necessary to the requested in-memory format
+during the png_image_finish_read() step.
+
+To write a PNG file using the simplified API:
+
+ 1) Declare a 'png_image' structure on the stack and memset()
+ it to all zero.
+
+ 2) Initialize the members of the structure that describe the
+ image, setting the 'format' member to the format of the
+ image in memory.
+
+ 3) Call the appropriate png_image_write... function with a
+ pointer to the image to write the PNG data.
+
+png_image is a structure that describes the in-memory format of an image
+when it is being read or define the in-memory format of an image that you
+need to write. The "png_image" structure contains the following members:
+
+ png_uint_32 version Set to PNG_IMAGE_VERSION
+ png_uint_32 width Image width in pixels (columns)
+ png_uint_32 height Image height in pixels (rows)
+ png_uint_32 format Image format as defined below
+ png_uint_32 flags A bit mask containing informational flags
+ png_controlp opaque Initialize to NULL, free with png_image_free
+ png_uint_32 colormap_entries; Number of entries in the color-map
+ png_uint_32 warning_or_error;
+ char message[64];
+
+In the event of an error or warning the following field warning_or_error
+field will be set to a non-zero value and the 'message' field will contain
+a '\0' terminated string with the libpng error or warning message. If both
+warnings and an error were encountered, only the error is recorded. If there
+are multiple warnings, only the first one is recorded.
+
+The upper 30 bits of this value are reserved; the low two bits contain
+a two bit code such that a value more than 1 indicates a failure in the API
+just called:
+
+ 0 - no warning or error
+ 1 - warning
+ 2 - error
+ 3 - error preceded by warning
+
+The pixels (samples) of the image have one to four channels whose components
+have original values in the range 0 to 1.0:
+
+ 1: A single gray or luminance channel (G).
+ 2: A gray/luminance channel and an alpha channel (GA).
+ 3: Three red, green, blue color channels (RGB).
+ 4: Three color channels and an alpha channel (RGBA).
+
+The channels are encoded in one of two ways:
+
+ a) As a small integer, value 0..255, contained in a single byte. For the
+alpha channel the original value is simply value/255. For the color or
+luminance channels the value is encoded according to the sRGB specification
+and matches the 8-bit format expected by typical display devices.
+
+The color/gray channels are not scaled (pre-multiplied) by the alpha
+channel and are suitable for passing to color management software.
+
+ b) As a value in the range 0..65535, contained in a 2-byte integer, in
+the native byte order of the platform on which the application is running.
+All channels can be converted to the original value by dividing by 65535; all
+channels are linear. Color channels use the RGB encoding (RGB end-points) of
+the sRGB specification. This encoding is identified by the
+PNG_FORMAT_FLAG_LINEAR flag below.
+
+When an alpha channel is present it is expected to denote pixel coverage
+of the color or luminance channels and is returned as an associated alpha
+channel: the color/gray channels are scaled (pre-multiplied) by the alpha
+value.
+
+When a color-mapped image is used as a result of calling
+png_image_read_colormap or png_image_write_colormap the channels are encoded
+in the color-map and the descriptions above apply to the color-map entries.
+The image data is encoded as small integers, value 0..255, that index the
+entries in the color-map. One integer (one byte) is stored for each pixel.
+
+PNG_FORMAT_*
+
+The #defines to be used in png_image::format. Each #define identifies a
+particular layout of channel data and, if present, alpha values. There are
+separate defines for each of the two channel encodings.
+
+A format is built up using single bit flag values. Not all combinations are
+valid: use the bit flag values below for testing a format returned by the
+read APIs, but set formats from the derived values.
+
+When reading or writing color-mapped images the format should be set to the
+format of the entries in the color-map then png_image_{read,write}_colormap
+called to read or write the color-map and set the format correctly for the
+image data. Do not set the PNG_FORMAT_FLAG_COLORMAP bit directly!
+
+NOTE: libpng can be built with particular features disabled, if you see
+compiler errors because the definition of one of the following flags has been
+compiled out it is because libpng does not have the required support. It is
+possible, however, for the libpng configuration to enable the format on just
+read or just write; in that case you may see an error at run time. You can
+guard against this by checking for the definition of:
+
+ PNG_SIMPLIFIED_{READ,WRITE}_{BGR,AFIRST}_SUPPORTED
+
+ PNG_FORMAT_FLAG_ALPHA 0x01 format with an alpha channel
+ PNG_FORMAT_FLAG_COLOR 0x02 color format: otherwise grayscale
+ PNG_FORMAT_FLAG_LINEAR 0x04 png_uint_16 channels else png_byte
+ PNG_FORMAT_FLAG_COLORMAP 0x08 libpng use only
+ PNG_FORMAT_FLAG_BGR 0x10 BGR colors, else order is RGB
+ PNG_FORMAT_FLAG_AFIRST 0x20 alpha channel comes first
+
+Supported formats are as follows. Future versions of libpng may support more
+formats; for compatibility with older versions simply check if the format
+macro is defined using #ifdef. These defines describe the in-memory layout
+of the components of the pixels of the image.
+
+First the single byte formats:
+
+ PNG_FORMAT_GRAY 0
+ PNG_FORMAT_GA PNG_FORMAT_FLAG_ALPHA
+ PNG_FORMAT_AG (PNG_FORMAT_GA|PNG_FORMAT_FLAG_AFIRST)
+ PNG_FORMAT_RGB PNG_FORMAT_FLAG_COLOR
+ PNG_FORMAT_BGR (PNG_FORMAT_FLAG_COLOR|PNG_FORMAT_FLAG_BGR)
+ PNG_FORMAT_RGBA (PNG_FORMAT_RGB|PNG_FORMAT_FLAG_ALPHA)
+ PNG_FORMAT_ARGB (PNG_FORMAT_RGBA|PNG_FORMAT_FLAG_AFIRST)
+ PNG_FORMAT_BGRA (PNG_FORMAT_BGR|PNG_FORMAT_FLAG_ALPHA)
+ PNG_FORMAT_ABGR (PNG_FORMAT_BGRA|PNG_FORMAT_FLAG_AFIRST)
+
+Then the linear 2-byte formats. When naming these "Y" is used to
+indicate a luminance (gray) channel. The component order within the pixel
+is always the same - there is no provision for swapping the order of the
+components in the linear format. The components are 16-bit integers in
+the native byte order for your platform, and there is no provision for
+swapping the bytes to a different endian condition.
+
+ PNG_FORMAT_LINEAR_Y PNG_FORMAT_FLAG_LINEAR
+ PNG_FORMAT_LINEAR_Y_ALPHA
+ (PNG_FORMAT_FLAG_LINEAR|PNG_FORMAT_FLAG_ALPHA)
+ PNG_FORMAT_LINEAR_RGB
+ (PNG_FORMAT_FLAG_LINEAR|PNG_FORMAT_FLAG_COLOR)
+ PNG_FORMAT_LINEAR_RGB_ALPHA
+ (PNG_FORMAT_FLAG_LINEAR|PNG_FORMAT_FLAG_COLOR|
+ PNG_FORMAT_FLAG_ALPHA)
+
+Color-mapped formats are obtained by calling png_image_{read,write}_colormap,
+as appropriate after setting png_image::format to the format of the color-map
+to be read or written. Applications may check the value of
+PNG_FORMAT_FLAG_COLORMAP to see if they have called the colormap API. The
+format of the color-map may be extracted using the following macro.
+
+ PNG_FORMAT_OF_COLORMAP(fmt) ((fmt) & ~PNG_FORMAT_FLAG_COLORMAP)
+
+PNG_IMAGE macros
+
+These are convenience macros to derive information from a png_image
+structure. The PNG_IMAGE_SAMPLE_ macros return values appropriate to the
+actual image sample values - either the entries in the color-map or the
+pixels in the image. The PNG_IMAGE_PIXEL_ macros return corresponding values
+for the pixels and will always return 1 after a call to
+png_image_{read,write}_colormap. The remaining macros return information
+about the rows in the image and the complete image.
+
+NOTE: All the macros that take a png_image::format parameter are compile time
+constants if the format parameter is, itself, a constant. Therefore these
+macros can be used in array declarations and case labels where required.
+Similarly the macros are also pre-processor constants (sizeof is not used) so
+they can be used in #if tests.
+
+First the information about the samples.
+
+ PNG_IMAGE_SAMPLE_CHANNELS(fmt)
+ Returns the total number of channels in a given format: 1..4
+
+ PNG_IMAGE_SAMPLE_COMPONENT_SIZE(fmt)
+ Returns the size in bytes of a single component of a pixel or color-map
+ entry (as appropriate) in the image.
+
+ PNG_IMAGE_SAMPLE_SIZE(fmt)
+ This is the size of the sample data for one sample. If the image is
+ color-mapped it is the size of one color-map entry (and image pixels are
+ one byte in size), otherwise it is the size of one image pixel.
+
+ PNG_IMAGE_COLORMAP_SIZE(fmt)
+ The size of the color-map required by the format; this is the size of the
+ color-map buffer passed to the png_image_{read,write}_colormap APIs, it is
+ a fixed number determined by the format so can easily be allocated on the
+ stack if necessary.
+
+#define PNG_IMAGE_MAXIMUM_COLORMAP_COMPONENTS(fmt)\

+
+ PNG_IMAGE_PIXEL_COMPONENT_SIZE(fmt)\

+ image.
+
+ PNG_IMAGE_PIXEL_SIZE(fmt)
+ The size, in bytes, of a complete pixel; 1 for a color-mapped image.
+
+Information about the whole row, or whole image
+
+ PNG_IMAGE_ROW_STRIDE(image)
+ Returns the total number of components in a single row of the image; this
+ is the minimum 'row stride', the minimum count of components between each
+ row. For a color-mapped image this is the minimum number of bytes in a
+ row.
+
+ If you need the stride measured in bytes, row_stride_bytes is
+ PNG_IMAGE_ROW_STRIDE(image) * PNG_IMAGE_PIXEL_COMPONENT_SIZE(fmt)
+ plus any padding bytes that your application might need, for example
+ to start the next row on a 4-byte boundary.
+
+ PNG_IMAGE_BUFFER_SIZE(image, row_stride)
+ Returns the size, in bytes, of an image buffer given a png_image and a row
+ stride - the number of components to leave space for in each row. This
+ macro takes care of multiplying row_stride by PNG_IMAGE_PIXEL_COMONENT_SIZE
+ when the image has 2-byte components.
+
+ PNG_IMAGE_FLAG_COLORSPACE_NOT_sRGB == 0x01
+ This indicates the the RGB values of the in-memory bitmap do not
+ correspond to the red, green and blue end-points defined by sRGB.
+
+ PNG_IMAGE_FLAG_COLORMAP == 0x02
+ The PNG is color-mapped. If this flag is set png_image_read_colormap
+ can be used without further loss of image information. If it is not set
+ png_image_read_colormap will cause significant loss if the image has any
+
+READ APIs
+
+ The png_image passed to the read APIs must have been initialized by setting
+ the png_controlp field 'opaque' to NULL (or, better, memset the whole thing.)
+
+ int png_image_begin_read_from_file( png_imagep image,
+ const char *file_name)
+
+ The named file is opened for read and the image header
+ is filled in from the PNG header in the file.
+
+ int png_image_begin_read_from_stdio (png_imagep image,
+ FILE* file)
+
+ The PNG header is read from the stdio FILE object.
+
+ int png_image_begin_read_from_memory(png_imagep image,

+
+ The PNG header is read from the given memory buffer.
+
+ int png_image_finish_read(png_imagep image,
+ png_colorp background, void *buffer,
+ png_int_32 row_stride, void *colormap));
+
+ Finish reading the image into the supplied buffer and
+ clean up the png_image structure.
+
+ row_stride is the step, in png_byte or png_uint_16 units
+ as appropriate, between adjacent rows. A positive stride
+ indicates that the top-most row is first in the buffer -
+ the normal top-down arrangement. A negative stride
+ indicates that the bottom-most row is first in the buffer.
+
+ background need only be supplied if an alpha channel must
+ be removed from a png_byte format and the removal is to be
+ done by compositing on a solid color; otherwise it may be
+ NULL and any composition will be done directly onto the
+ buffer. The value is an sRGB color to use for the
+ background, for grayscale output the green channel is used.
+
+ For linear output removing the alpha channel is always done
+ by compositing on black.
+
+ void png_image_free(png_imagep image)
+
+ Free any data allocated by libpng in image->opaque,
+ setting the pointer to NULL. May be called at any time
+ after the structure is initialized.
+
+When the simplified API needs to convert between sRGB and linear colorspaces,
+the actual sRGB transfer curve defined in the sRGB specification (see the

+For write you must initialize a png_image structure to describe the image to

+
+ version: must be set to PNG_IMAGE_VERSION
+ opaque: must be initialized to NULL
+ width: image width in pixels
+ height: image height in rows

+ PNG_IMAGE_FLAG_COLORSPACE_NOT_sRGB for color format images
+ where the RGB values do not correspond to the colors in sRGB.

+
+ int png_image_write_to_file, (png_imagep image,

+
+ int png_image_write_to_stdio(png_imagep image, FILE *file,
+ int convert_to_8_bit, const void *buffer,
+ png_int_32 row_stride, const void *colormap)
+
+ Write the image to the given (FILE*).
+
+With all write APIs if image is in one of the linear formats with
+(png_uint_16) data then setting convert_to_8_bit will cause the output to be
+a (png_byte) PNG gamma encoded according to the sRGB specification, otherwise
+a 16-bit linear encoded PNG file is written.
+
+With all APIs row_stride is handled as in the read APIs - it is the spacing
+from one row to the next in component sized units (float) and if negative
+indicates a bottom-up row layout in the buffer.
+
+Note that the write API does not support interlacing, sub-8-bit pixels,
+and indexed (paletted) images.

-B.2 Changes to the configuration mechanism
-
-Prior to libpng-1.5.0 library builders who needed to configure libpng
-had either to modify the exported pngconf.h header file to add system
-specific configuration or had to write feature selection macros into
-pngusr.h and cause this to be included into pngconf.h by defining

-
-These mechanisms still work in the configure build and in any makefile
-build that builds pnglibconf.h, although the feature selection macros
-have changed somewhat as described above. In 1.5.0, however, pngusr.h is
-processed only once, when the exported header file pnglibconf.h is built.
-pngconf.h no longer includes pngusr.h, therefore pngusr.h is ignored after the
-build of pnglibconf.h and it is never included in an application build.
-
-The rarely used alternative of adding a list of feature macros to the
-CFLAGS setting in the build also still works; however, the macros will be
-copied to pnglibconf.h and this may produce macro redefinition warnings
-when the individual C files are compiled.
-
-All configuration now only works if pnglibconf.h is built from
-scripts/pnglibconf.dfa. This requires the program awk. Brian Kernighan
-(the original author of awk) maintains C source code of that awk and this
-and all known later implementations (often called by subtly different

-The Sun Microsystems (now Oracle) program 'awk' is an earlier version
-and does not work; this may also apply to other systems that have a
-functioning awk called 'nawk'.
-
-Configuration options are now documented in scripts/pnglibconf.dfa. This
-file also includes dependency information that ensures a configuration is
-consistent; that is, if a feature is switched off dependent features are
-also removed. As a recommended alternative to using feature macros in
-pngusr.h a system builder may also define equivalent options in pngusr.dfa

-XI. Detecting libpng
+XII. Changes to Libpng from version 1.5.x to 1.6.x
+
+A "simplified API" has been added (see documentation in png.h and a simple
+example in contrib/examples/pngtopng.c). The new publicly visible API
+includes the following:
+
+ macros:
+ PNG_FORMAT_*
+ PNG_IMAGE_*
+ structures:
+ png_control
+ png_image
+ read functions
+ png_image_begin_read_from_file()
+ png_image_begin_read_from_stdio()
+ png_image_begin_read_from_memory()
+ png_image_finish_read()
+ png_image_free()
+ write functions
+ png_image_write_to_file()
+ png_image_write_to_stdio()
+
+Starting with libpng-1.6.0, you can configure libpng to prefix all exported
+symbols, using the PNG_PREFIX macro.
+
+We no longer include string.h in png.h. The include statement has been moved
+to pngpriv.h, where it is not accessible by applications. Applications that
+need access to information in string.h must add an '#include <string.h>'
+directive. It does not matter whether this is placed prior to or after
+the '#include "png.h"' directive.
+
+The following API are now DEPRECATED:
+ png_info_init_3()
+ png_convert_to_rfc1123() which has been replaced
+ with png_convert_to_rfc1123_buffer()
+ png_malloc_default()
+ png_free_default()
+ png_reset_zstream()
+
+The following have been removed:
+ png_get_io_chunk_name(), which has been replaced
+ with png_get_io_chunk_type(). The new
+ function returns a 32-bit integer instead of
+ a string.
+ The png_sizeof(), png_strlen(), png_memcpy(), png_memcmp(), and
+ png_memset() macros are no longer used in the libpng sources and
+ have been removed. These had already been made invisible to applications
+ (i.e., defined in the private pngpriv.h header file) since libpng-1.5.0.
+
+The signatures of many exported functions were changed, such that
+ png_structp became png_structrp or png_const_structrp
+ png_infop became png_inforp or png_const_inforp
+where "rp" indicates a "restricted pointer".
+
+Error detection in some chunks has improved; in particular the iCCP chunk
+reader now does pretty complete validation of the basic format. Some bad
+profiles that were previously accepted are now accepted with a warning or
+rejected, depending upon the png_set_benign_errors() setting, in particular
+the very old broken Microsoft/HP 3144-byte sRGB profile. Starting with
+libpng-1.6.11, recognizing and checking sRGB profiles can be avoided by
+means of
+
+ #if defined(PNG_SKIP_sRGB_CHECK_PROFILE) && \
+ defined(PNG_SET_OPTION_SUPPORTED)
+ png_set_option(png_ptr, PNG_SKIP_sRGB_CHECK_PROFILE,
+ PNG_OPTION_ON);
+ #endif
+
+It's not a good idea to do this if you are using the new "simplified API",
+which needs to be able to recognize sRGB profiles conveyed via the iCCP
+chunk.
+
+The PNG spec requirement that only grayscale profiles may appear in images
+with color type 0 or 4 and that even if the image only contains gray pixels,
+only RGB profiles may appear in images with color type 2, 3, or 6, is now
+enforced. The sRGB chunk is allowed to appear in images with any color type
+and is interpreted by libpng to convey a one-tracer-curve gray profile or a
+three-tracer-curve RGB profile as appropriate.
+
+Prior to libpng-1.6.0 a warning would be issued if the iTXt chunk contained
+an empty language field or an empty translated keyword. Both of these
+are allowed by the PNG specification, so these warnings are no longer issued.
+
+The library now issues an error if the application attempts to set a
+transform after it calls png_read_update_info() or if it attempts to call
+both png_read_update_info() and png_start_read_image() or to call either
+of them more than once.
+
+The default condition for benign_errors is now to treat benign errors as
+warnings while reading and as errors while writing.
+
+The library now issues a warning if both background processing and RGB to
+gray are used when gamma correction happens. As with previous versions of
+the library the results are numerically very incorrect in this case.
+
+There are some minor arithmetic changes in some transforms such as
+png_set_background(), that might be detected by certain regression tests.
+
+Unknown chunk handling has been improved internally, without any API change.
+This adds more correct option control of the unknown handling, corrects
+a pre-existing bug where the per-chunk 'keep' setting is ignored, and makes
+it possible to skip IDAT chunks in the sequential reader.
+
+The machine-generated configure files are no longer included in branches
+libpng16 and later of the GIT repository. They continue to be included
+in the tarball releases, however.
+
+Libpng-1.6.0 through 1.6.2 used the CMF bytes at the beginning of the IDAT
+stream to set the size of the sliding window for reading instead of using the
+default 32-kbyte sliding window size. It was discovered that there are
+hundreds of PNG files in the wild that have incorrect CMF bytes that caused
+zlib to issue the "invalid distance too far back" error and reject the file.
+Libpng-1.6.3 and later calculate their own safe CMF from the image dimensions,
+provide a way to revert to the libpng-1.5.x behavior (ignoring the CMF bytes
+and using a 32-kbyte sliding window), by using
+
+ png_set_option(png_ptr, PNG_MAXIMUM_INFLATE_WINDOW,
+ PNG_OPTION_ON);
+
+and provide a tool (contrib/tools/pngfix) for rewriting a PNG file while
+optimizing the CMF bytes in its IDAT chunk correctly.
+
+Libpng-1.6.0 and libpng-1.6.1 wrote uncompressed iTXt chunks with the wrong
+length, which resulted in PNG files that cannot be read beyond the bad iTXt
+chunk. This error was fixed in libpng-1.6.3, and a tool (called
+contrib/tools/png-fix-itxt) has been added to the libpng distribution.

+values further because this avoids the need to decode and re-encode each
component value whenever arithmetic is performed. A lot of graphics software
uses linear values for this reason, often with higher precision component values
to preserve overall accuracy.
+
+The output_gamma value expresses how to decode the output values, not how
+they are encoded. The values used correspond to the normal numbers used to
+describe the overall gamma of a computer display system; for example 2.2 for
+an sRGB conformant system. The values are scaled by 100000 in the _fixed
+version of the API (so 220000 for sRGB.)
+
+The inverse of the value is always used to provide a default for the PNG file
+encoding if it has no gAMA chunk and if png_set_gamma() has not been called
+to override the PNG gamma information.
+
+When the ALPHA_OPTIMIZED mode is selected the output gamma is used to encode
+opaque pixels however pixels with lower alpha values are not encoded,
+regardless of the output gamma setting.
+
+When the standard Porter Duff handling is requested with mode 1 the output
+encoding is set to be linear and the output_gamma value is only relevant
+as a default for input data that has no gamma information. The linear output
+encoding will be overridden if png_set_gamma() is called - the results may be
+highly unexpected!
+
+The following numbers are derived from the sRGB standard and the research
+behind it. sRGB is defined to be approximated by a PNG gAMA chunk value of
+0.45455 (1/2.2) for PNG. The value implicitly includes any viewing
+correction required to take account of any differences in the color
+environment of the original scene and the intended display environment; the
+value expresses how to *decode* the image for display, not how the original
+data was *encoded*.
+
+sRGB provides a peg for the PNG standard by defining a viewing environment.
+sRGB itself, and earlier TV standards, actually use a more complex transform
+(a linear portion then a gamma 2.4 power law) than PNG can express. (PNG is
+limited to simple power laws.) By saying that an image for direct display on
+an sRGB conformant system should be stored with a gAMA chunk value of 45455
+(11.3.3.2 and 11.3.3.5 of the ISO PNG specification) the PNG specification
+makes it possible to derive values for other display systems and
+environments.
+
+The Mac value is deduced from the sRGB based on an assumption that the actual
+extra viewing correction used in early Mac display systems was implemented as
+a power 1.45 lookup table.
+
+Any system where a programmable lookup table is used or where the behavior of
+the final display device characteristics can be changed requires system
+specific code to obtain the current characteristic. However this can be
+difficult and most PNG gamma correction only requires an approximate value.
+
+By default, if png_set_alpha_mode() is not called, libpng assumes that all
+values are unencoded, linear, values and that the output device also has a
+linear characteristic. This is only very rarely correct - it is invariably
+better to call png_set_alpha_mode() with PNG_DEFAULT_sRGB than rely on the
+default if you don't know what the right answer is!
+
+The special value PNG_GAMMA_MAC_18 indicates an older Mac system (pre Mac OS
+10.6) which used a correction table to implement a somewhat lower gamma on an
+otherwise sRGB system.
+
+Both these values are reserved (not simple gamma values) in order to allow
+more precise correction internally in the future.
+
+NOTE: the values can be passed to either the fixed or floating
+point APIs, but the floating point API will also accept floating point
+values.

+the output is always 16 bits per component. This permits accurate scaling
+and processing of the data. If you know that your input PNG files were
+generated locally you might need to replace PNG_DEFAULT_sRGB with the
+correct value for your system.
+
+ png_set_alpha_mode(pp, PNG_ALPHA_OPTIMIZED, PNG_DEFAULT_sRGB);
+
+If you just need to composite the PNG image onto an existing background
+and if you control the code that does this you can use the optimization
+setting. In this case you just copy completely opaque pixels to the
+output. For pixels that are not completely transparent (you just skip
+those) you do the composition math using png_composite or png_composite_16
+below then encode the resultant 8-bit or 16-bit values to match the output
+encoding.
+
+ Other cases
+
+If neither the PNG nor the standard linear encoding work for you because
+of the software or hardware you use then you have a big problem. The PNG
+case will probably result in halos around the image. The linear encoding
+will probably result in a washed out, too bright, image (it's actually too
+contrasty.) Try the ALPHA_OPTIMIZED mode above - this will probably
+substantially reduce the halos. Alternatively try:
+
+ png_set_alpha_mode(pp, PNG_ALPHA_BROKEN, PNG_DEFAULT_sRGB);
+
+This option will also reduce the halos, but there will be slight dark
+halos round the opaque parts of the image where the background is light.
+In the OPTIMIZED mode the halos will be light halos where the background
+is dark. Take your pick - the halos are unavoidable unless you can get
+your hardware/software fixed! (The OPTIMIZED approach is slightly
+faster.)
+
+When the default gamma of PNG files doesn't match the output gamma.
+If you have PNG files with no gamma information png_set_alpha_mode allows
+you to provide a default gamma, but it also sets the ouput gamma to the
+matching value. If you know your PNG files have a gamma that doesn't
+match the output you can take advantage of the fact that
+png_set_alpha_mode always sets the output gamma but only sets the PNG
+default if it is not already set:
+
+ png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
+ png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
+
+The first call sets both the default and the output gamma values, the
+second call overrides the output gamma without changing the default. This
+is easier than achieving the same effect with png_set_gamma. You must use
+PNG_ALPHA_PNG for the first call - internal checking in png_set_alpha will
+fire if more than one call to png_set_alpha_mode and png_set_background is
+made in the same read operation, however multiple calls with PNG_ALPHA_PNG
+are ignored.
+
If you don't need, or can't handle, the alpha channel you can call
png_set_background() to remove it by compositing against a fixed color. Don't
call png_set_strip_alpha() to do this - it will leave spurious pixel values in

-.SH V. Modifying/Customizing libpng:
+.SH V. Simplified API
+
+The simplified API, which became available in libpng-1.6.0, hides the details
+of both libpng and the PNG file format itself.
+It allows PNG files to be read into a very limited number of
+in-memory bitmap formats or to be written from the same formats. If these
+formats do not accommodate your needs then you can, and should, use the more
+sophisticated APIs above - these support a wide variety of in-memory formats
+and a wide variety of sophisticated transformations to those formats as well
+as a wide variety of APIs to manipulate ancilliary information.
+
+To read a PNG file using the simplified API:
+
+ 1) Declare a 'png_image' structure (see below) on the
+ stack and memset() it to all zero.
+
+ 2) Call the appropriate png_image_begin_read... function.
+
+ 3) Set the png_image 'format' member to the required
+ format and allocate a buffer for the image.
+
+ 4) Call png_image_finish_read to read the image into
+ your buffer.
+
+There are no restrictions on the format of the PNG input itself; all valid
+color types, bit depths, and interlace methods are acceptable, and the
+input image is transformed as necessary to the requested in-memory format
+during the png_image_finish_read() step.
+
+To write a PNG file using the simplified API:
+
+ 1) Declare a 'png_image' structure on the stack and memset()
+ it to all zero.
+
+ 2) Initialize the members of the structure that describe the
+ image, setting the 'format' member to the format of the
+ image in memory.
+
+ 3) Call the appropriate png_image_write... function with a
+ pointer to the image to write the PNG data.
+
+png_image is a structure that describes the in-memory format of an image
+when it is being read or define the in-memory format of an image that you
+need to write. The "png_image" structure contains the following members:
+
+ png_uint_32 version Set to PNG_IMAGE_VERSION
+ png_uint_32 width Image width in pixels (columns)
+ png_uint_32 height Image height in pixels (rows)
+ png_uint_32 format Image format as defined below
+ png_uint_32 flags A bit mask containing informational flags
+ png_controlp opaque Initialize to NULL, free with png_image_free
+ png_uint_32 colormap_entries; Number of entries in the color-map
+ png_uint_32 warning_or_error;
+ char message[64];
+
+In the event of an error or warning the following field warning_or_error
+field will be set to a non-zero value and the 'message' field will contain
+a '\0' terminated string with the libpng error or warning message. If both
+warnings and an error were encountered, only the error is recorded. If there
+are multiple warnings, only the first one is recorded.
+
+The upper 30 bits of this value are reserved; the low two bits contain
+a two bit code such that a value more than 1 indicates a failure in the API
+just called:
+
+ 0 - no warning or error
+ 1 - warning
+ 2 - error
+ 3 - error preceded by warning
+
+The pixels (samples) of the image have one to four channels whose components
+have original values in the range 0 to 1.0:
+
+ 1: A single gray or luminance channel (G).
+ 2: A gray/luminance channel and an alpha channel (GA).
+ 3: Three red, green, blue color channels (RGB).
+ 4: Three color channels and an alpha channel (RGBA).
+
+The channels are encoded in one of two ways:
+
+ a) As a small integer, value 0..255, contained in a single byte. For the
+alpha channel the original value is simply value/255. For the color or
+luminance channels the value is encoded according to the sRGB specification
+and matches the 8-bit format expected by typical display devices.
+
+The color/gray channels are not scaled (pre-multiplied) by the alpha
+channel and are suitable for passing to color management software.
+
+ b) As a value in the range 0..65535, contained in a 2-byte integer, in
+the native byte order of the platform on which the application is running.
+All channels can be converted to the original value by dividing by 65535; all
+channels are linear. Color channels use the RGB encoding (RGB end-points) of
+the sRGB specification. This encoding is identified by the
+PNG_FORMAT_FLAG_LINEAR flag below.
+
+When an alpha channel is present it is expected to denote pixel coverage
+of the color or luminance channels and is returned as an associated alpha
+channel: the color/gray channels are scaled (pre-multiplied) by the alpha
+value.
+
+When a color-mapped image is used as a result of calling
+png_image_read_colormap or png_image_write_colormap the channels are encoded
+in the color-map and the descriptions above apply to the color-map entries.
+The image data is encoded as small integers, value 0..255, that index the
+entries in the color-map. One integer (one byte) is stored for each pixel.
+
+PNG_FORMAT_*
+
+The #defines to be used in png_image::format. Each #define identifies a
+particular layout of channel data and, if present, alpha values. There are
+separate defines for each of the two channel encodings.
+
+A format is built up using single bit flag values. Not all combinations are
+valid: use the bit flag values below for testing a format returned by the
+read APIs, but set formats from the derived values.
+
+When reading or writing color-mapped images the format should be set to the
+format of the entries in the color-map then png_image_{read,write}_colormap
+called to read or write the color-map and set the format correctly for the
+image data. Do not set the PNG_FORMAT_FLAG_COLORMAP bit directly!
+
+NOTE: libpng can be built with particular features disabled, if you see
+compiler errors because the definition of one of the following flags has been
+compiled out it is because libpng does not have the required support. It is
+possible, however, for the libpng configuration to enable the format on just
+read or just write; in that case you may see an error at run time. You can
+guard against this by checking for the definition of:
+
+ PNG_SIMPLIFIED_{READ,WRITE}_{BGR,AFIRST}_SUPPORTED
+
+ PNG_FORMAT_FLAG_ALPHA 0x01 format with an alpha channel
+ PNG_FORMAT_FLAG_COLOR 0x02 color format: otherwise grayscale
+ PNG_FORMAT_FLAG_LINEAR 0x04 png_uint_16 channels else png_byte
+ PNG_FORMAT_FLAG_COLORMAP 0x08 libpng use only
+ PNG_FORMAT_FLAG_BGR 0x10 BGR colors, else order is RGB
+ PNG_FORMAT_FLAG_AFIRST 0x20 alpha channel comes first
+
+Supported formats are as follows. Future versions of libpng may support more
+formats; for compatibility with older versions simply check if the format
+macro is defined using #ifdef. These defines describe the in-memory layout
+of the components of the pixels of the image.
+
+First the single byte formats:
+
+ PNG_FORMAT_GRAY 0
+ PNG_FORMAT_GA PNG_FORMAT_FLAG_ALPHA
+ PNG_FORMAT_AG (PNG_FORMAT_GA|PNG_FORMAT_FLAG_AFIRST)
+ PNG_FORMAT_RGB PNG_FORMAT_FLAG_COLOR

+ PNG_FORMAT_BGRA (PNG_FORMAT_BGR|PNG_FORMAT_FLAG_ALPHA)
+ PNG_FORMAT_ABGR (PNG_FORMAT_BGRA|PNG_FORMAT_FLAG_AFIRST)
+
+Then the linear 2-byte formats. When naming these "Y" is used to
+indicate a luminance (gray) channel. The component order within the pixel
+is always the same - there is no provision for swapping the order of the
+components in the linear format. The components are 16-bit integers in
+the native byte order for your platform, and there is no provision for
+swapping the bytes to a different endian condition.
+

+ (PNG_FORMAT_FLAG_LINEAR|PNG_FORMAT_FLAG_COLOR)
+ PNG_FORMAT_LINEAR_RGB_ALPHA
+ (PNG_FORMAT_FLAG_LINEAR|PNG_FORMAT_FLAG_COLOR|
+ PNG_FORMAT_FLAG_ALPHA)
+
+Color-mapped formats are obtained by calling png_image_{read,write}_colormap,
+as appropriate after setting png_image::format to the format of the color-map
+to be read or written. Applications may check the value of
+PNG_FORMAT_FLAG_COLORMAP to see if they have called the colormap API. The

+PNG_IMAGE macros
+
+These are convenience macros to derive information from a png_image
+structure. The PNG_IMAGE_SAMPLE_ macros return values appropriate to the
+actual image sample values - either the entries in the color-map or the
+pixels in the image. The PNG_IMAGE_PIXEL_ macros return corresponding values
+for the pixels and will always return 1 after a call to
+png_image_{read,write}_colormap. The remaining macros return information
+about the rows in the image and the complete image.
+
+NOTE: All the macros that take a png_image::format parameter are compile time
+constants if the format parameter is, itself, a constant. Therefore these
+macros can be used in array declarations and case labels where required.
+Similarly the macros are also pre-processor constants (sizeof is not used) so

-All configuration now only works if pnglibconf.h is built from
-scripts/pnglibconf.dfa. This requires the program awk. Brian Kernighan
-(the original author of awk) maintains C source code of that awk and this
-and all known later implementations (often called by subtly different
-names - nawk and gawk for example) are adequate to build pnglibconf.h.
-The Sun Microsystems (now Oracle) program 'awk' is an earlier version
-and does not work; this may also apply to other systems that have a
-functioning awk called 'nawk'.
-
-Configuration options are now documented in scripts/pnglibconf.dfa. This
-file also includes dependency information that ensures a configuration is
-consistent; that is, if a feature is switched off dependent features are
-also removed. As a recommended alternative to using feature macros in
-pngusr.h a system builder may also define equivalent options in pngusr.dfa
-(or, indeed, any file) and add that to the configuration by setting
-DFA_XTRA to the file name. The makefiles in contrib/pngminim illustrate
-how to do this, and a case where pngusr.h is still required.

-.SH XI. Detecting libpng
+.SH XII. Changes to Libpng from version 1.5.x to 1.6.x
+
+A "simplified API" has been added (see documentation in png.h and a simple
+example in contrib/examples/pngtopng.c). The new publicly visible API
+includes the following:
+
+ macros:
+ PNG_FORMAT_*
+ PNG_IMAGE_*
+ structures:
+ png_control
+ png_image
+ read functions
+ png_image_begin_read_from_file()
+ png_image_begin_read_from_stdio()
+ png_image_begin_read_from_memory()
+ png_image_finish_read()
+ png_image_free()
+ write functions
+ png_image_write_to_file()
+ png_image_write_to_stdio()
+
+Starting with libpng-1.6.0, you can configure libpng to prefix all exported
+symbols, using the PNG_PREFIX macro.
+
+We no longer include string.h in png.h. The include statement has been moved
+to pngpriv.h, where it is not accessible by applications. Applications that
+need access to information in string.h must add an '#include <string.h>'
+directive. It does not matter whether this is placed prior to or after
+the '#include "png.h"' directive.
+
+The following API are now DEPRECATED:
+ png_info_init_3()
+ png_convert_to_rfc1123() which has been replaced
+ with png_convert_to_rfc1123_buffer()
+ png_malloc_default()
+ png_free_default()
+ png_reset_zstream()
+
+The following have been removed:
+ png_get_io_chunk_name(), which has been replaced
+ with png_get_io_chunk_type(). The new
+ function returns a 32-bit integer instead of
+ a string.
+ The png_sizeof(), png_strlen(), png_memcpy(), png_memcmp(), and
+ png_memset() macros are no longer used in the libpng sources and
+ have been removed. These had already been made invisible to applications
+ (i.e., defined in the private pngpriv.h header file) since libpng-1.5.0.
+
+The signatures of many exported functions were changed, such that
+ png_structp became png_structrp or png_const_structrp
+ png_infop became png_inforp or png_const_inforp
+where "rp" indicates a "restricted pointer".
+
+Error detection in some chunks has improved; in particular the iCCP chunk
+reader now does pretty complete validation of the basic format. Some bad
+profiles that were previously accepted are now accepted with a warning or
+rejected, depending upon the png_set_benign_errors() setting, in particular
+the very old broken Microsoft/HP 3144-byte sRGB profile. Starting with
+libpng-1.6.11, recognizing and checking sRGB profiles can be avoided by
+means of
+
+ #if defined(PNG_SKIP_sRGB_CHECK_PROFILE) && \
+ defined(PNG_SET_OPTION_SUPPORTED)
+ png_set_option(png_ptr, PNG_SKIP_sRGB_CHECK_PROFILE,
+ PNG_OPTION_ON);
+ #endif
+
+It's not a good idea to do this if you are using the new "simplified API",
+which needs to be able to recognize sRGB profiles conveyed via the iCCP
+chunk.
+
+The PNG spec requirement that only grayscale profiles may appear in images
+with color type 0 or 4 and that even if the image only contains gray pixels,
+only RGB profiles may appear in images with color type 2, 3, or 6, is now
+enforced. The sRGB chunk is allowed to appear in images with any color type
+and is interpreted by libpng to convey a one-tracer-curve gray profile or a
+three-tracer-curve RGB profile as appropriate.
+
+Prior to libpng-1.6.0 a warning would be issued if the iTXt chunk contained
+an empty language field or an empty translated keyword. Both of these
+are allowed by the PNG specification, so these warnings are no longer issued.
+
+The library now issues an error if the application attempts to set a
+transform after it calls png_read_update_info() or if it attempts to call
+both png_read_update_info() and png_start_read_image() or to call either
+of them more than once.
+
+The default condition for benign_errors is now to treat benign errors as
+warnings while reading and as errors while writing.
+
+The library now issues a warning if both background processing and RGB to
+gray are used when gamma correction happens. As with previous versions of
+the library the results are numerically very incorrect in this case.
+
+There are some minor arithmetic changes in some transforms such as
+png_set_background(), that might be detected by certain regression tests.
+
+Unknown chunk handling has been improved internally, without any API change.
+This adds more correct option control of the unknown handling, corrects
+a pre-existing bug where the per-chunk 'keep' setting is ignored, and makes
+it possible to skip IDAT chunks in the sequential reader.
+
+The machine-generated configure files are no longer included in branches
+libpng16 and later of the GIT repository. They continue to be included
+in the tarball releases, however.
+
+Libpng-1.6.0 through 1.6.2 used the CMF bytes at the beginning of the IDAT
+stream to set the size of the sliding window for reading instead of using the
+default 32-kbyte sliding window size. It was discovered that there are
+hundreds of PNG files in the wild that have incorrect CMF bytes that caused
+zlib to issue the "invalid distance too far back" error and reject the file.
+Libpng-1.6.3 and later calculate their own safe CMF from the image dimensions,
+provide a way to revert to the libpng-1.5.x behavior (ignoring the CMF bytes
+and using a 32-kbyte sliding window), by using
+
+ png_set_option(png_ptr, PNG_MAXIMUM_INFLATE_WINDOW,
+ PNG_OPTION_ON);
+
+and provide a tool (contrib/tools/pngfix) for rewriting a PNG file while
+optimizing the CMF bytes in its IDAT chunk correctly.
+
+Libpng-1.6.0 and libpng-1.6.1 wrote uncompressed iTXt chunks with the wrong
+length, which resulted in PNG files that cannot be read beyond the bad iTXt
+chunk. This error was fixed in libpng-1.6.3, and a tool (called
+contrib/tools/png-fix-itxt) has been added to the libpng distribution.

- * derived values were recorded in the cHRM chunk;
- * (red,green,blue,white)x(x,y). This loses one degree of freedom and
- * therefore an arbitrary ninth value has to be introduced to undo the
- * original transformations.
- *
- * Think of the original end-points as points in (X,Y,Z) space. The
- * chromaticity values (c) have the property:
- *
- * C
- * c = ---------
- * X + Y + Z
- *
- * For each c (x,y,z) from the corresponding original C (X,Y,Z). Thus the
- * three chromaticity values (x,y,z) for each end-point obey the
- * relationship:
- *
- * x + y + z = 1
- *
- * This describes the plane in (X,Y,Z) space that intersects each axis at the
- * value 1.0; call this the chromaticity plane. Thus the chromaticity
- * calculation has scaled each end-point so that it is on the x+y+z=1 plane
- * and chromaticity is the intersection of the vector from the origin to the
- * (X,Y,Z) value with the chromaticity plane.
- *
- * To fully invert the chromaticity calculation we would need the three
- * end-point scale factors, (red-scale, green-scale, blue-scale), but these
- * were not recorded. Instead we calculated the reference white (X,Y,Z) and
- * recorded the chromaticity of this. The reference white (X,Y,Z) would have
- * given all three of the scale factors since:
- *
- * color-C = color-c * color-scale
- * white-C = red-C + green-C + blue-C
- * = red-c*red-scale + green-c*green-scale + blue-c*blue-scale
- *
- * But cHRM records only white-x and white-y, so we have lost the white scale
- * factor:
- *
- * white-C = white-c*white-scale
- *
- * To handle this the inverse transformation makes an arbitrary assumption
- * about white-scale:
- *
- * Assume: white-Y = 1.0
- * Hence: white-scale = 1/white-y
- * Or: red-Y + green-Y + blue-Y = 1.0
- *
- * Notice the last statement of the assumption gives an equation in three of
- * the nine values we want to calculate. 8 more equations come from the
- * above routine as summarised at the top above (the chromaticity
- * calculation):
- *
- * Given: color-x = color-X / (color-X + color-Y + color-Z)
- * Hence: (color-x - 1)*color-X + color.x*color-Y + color.x*color-Z = 0
- *
- * This is 9 simultaneous equations in the 9 variables "color-C" and can be
- * solved by Cramer's rule. Cramer's rule requires calculating 10 9x9 matrix
- * determinants, however this is not as bad as it seems because only 28 of
- * the total of 90 terms in the various matrices are non-zero. Nevertheless
- * Cramer's rule is notoriously numerically unstable because the determinant
- * calculation involves the difference of large, but similar, numbers. It is
- * difficult to be sure that the calculation is stable for real world values
- * and it is certain that it becomes unstable where the end points are close
- * together.
- *
- * So this code uses the perhaps slightly less optimal but more
- * understandable and totally obvious approach of calculating color-scale.
- *
- * This algorithm depends on the precision in white-scale and that is
- * (1/white-y), so we can immediately see that as white-y approaches 0 the
- * accuracy inherent in the cHRM chunk drops off substantially.
- *
- * libpng arithmetic: a simple invertion of the above equations
- * ------------------------------------------------------------
- *
- * white_scale = 1/white-y
- * white-X = white-x * white-scale
- * white-Y = 1.0
- * white-Z = (1 - white-x - white-y) * white_scale
- *
- * white-C = red-C + green-C + blue-C
- * = red-c*red-scale + green-c*green-scale + blue-c*blue-scale
- *
- * This gives us three equations in (red-scale,green-scale,blue-scale) where
- * all the coefficients are now known:
- *
- * red-x*red-scale + green-x*green-scale + blue-x*blue-scale
- * = white-x/white-y
- * red-y*red-scale + green-y*green-scale + blue-y*blue-scale = 1
- * red-z*red-scale + green-z*green-scale + blue-z*blue-scale
- * = (1 - white-x - white-y)/white-y
- *
- * In the last equation color-z is (1 - color-x - color-y) so we can add all
- * three equations together to get an alternative third:
- *
- * red-scale + green-scale + blue-scale = 1/white-y = white-scale
- *
- * So now we have a Cramer's rule solution where the determinants are just
- * 3x3 - far more tractible. Unfortunately 3x3 determinants still involve
- * multiplication of three coefficients so we can't guarantee to avoid
- * overflow in the libpng fixed point representation. Using Cramer's rule in
- * floating point is probably a good choice here, but it's not an option for
- * fixed point. Instead proceed to simplify the first two equations by
- * eliminating what is likely to be the largest value, blue-scale:
- *
- * blue-scale = white-scale - red-scale - green-scale
- *
- * Hence:
- *
- * (red-x - blue-x)*red-scale + (green-x - blue-x)*green-scale =
- * (white-x - blue-x)*white-scale
- *
- * (red-y - blue-y)*red-scale + (green-y - blue-y)*green-scale =
- * 1 - blue-y*white-scale
- *
- * And now we can trivially solve for (red-scale,green-scale):
- *
- * green-scale =
- * (white-x - blue-x)*white-scale - (red-x - blue-x)*red-scale
- * -----------------------------------------------------------
- * green-x - blue-x
- *
- * red-scale =
- * 1 - blue-y*white-scale - (green-y - blue-y) * green-scale
- * ---------------------------------------------------------
- * red-y - blue-y
- *
- * Hence:
- *
- * red-scale =
- * ( (green-x - blue-x) * (white-y - blue-y) -
- * (green-y - blue-y) * (white-x - blue-x) ) / white-y
- * -------------------------------------------------------------------------
- * (green-x - blue-x)*(red-y - blue-y)-(green-y - blue-y)*(red-x - blue-x)
- *
- * green-scale =
- * ( (red-y - blue-y) * (white-x - blue-x) -
- * (red-x - blue-x) * (white-y - blue-y) ) / white-y
- * -------------------------------------------------------------------------
- * (green-x - blue-x)*(red-y - blue-y)-(green-y - blue-y)*(red-x - blue-x)
- *
- * Accuracy:
- * The input values have 5 decimal digits of accuracy. The values are all in
- * the range 0 < value < 1, so simple products are in the same range but may
- * need up to 10 decimal digits to preserve the original precision and avoid
- * underflow. Because we are using a 32-bit signed representation we cannot
- * match this; the best is a little over 9 decimal digits, less than 10.
- *
- * The approach used here is to preserve the maximum precision within the
- * signed representation. Because the red-scale calculation above uses the
- * difference between two products of values that must be in the range -1..+1
- * it is sufficient to divide the product by 7; ceil(100,000/32767*2). The
- * factor is irrelevant in the calculation because it is applied to both
- * numerator and denominator.
- *
- * Note that the values of the differences of the products of the
- * chromaticities in the above equations tend to be small, for example for
- * the sRGB chromaticities they are:
- *
- * red numerator: -0.04751
- * green numerator: -0.08788
- * denominator: -0.2241 (without white-y multiplication)
- *
- * The resultant Y coefficients from the chromaticities of some widely used
- * color space definitions are (to 15 decimal places):
- *
- * sRGB
- * 0.212639005871510 0.715168678767756 0.072192315360734

+ * derived values were recorded in the cHRM chunk;
+ * (red,green,blue,white)x(x,y). This loses one degree of freedom and
+ * therefore an arbitrary ninth value has to be introduced to undo the
+ * original transformations.
+ *
+ * Think of the original end-points as points in (X,Y,Z) space. The
+ * chromaticity values (c) have the property:
+ *
+ * C
+ * c = ---------
+ * X + Y + Z
+ *
+ * For each c (x,y,z) from the corresponding original C (X,Y,Z). Thus the
+ * three chromaticity values (x,y,z) for each end-point obey the
+ * relationship:
+ *
+ * x + y + z = 1
+ *
+ * This describes the plane in (X,Y,Z) space that intersects each axis at the
+ * value 1.0; call this the chromaticity plane. Thus the chromaticity
+ * calculation has scaled each end-point so that it is on the x+y+z=1 plane
+ * and chromaticity is the intersection of the vector from the origin to the
+ * (X,Y,Z) value with the chromaticity plane.
+ *
+ * To fully invert the chromaticity calculation we would need the three
+ * end-point scale factors, (red-scale, green-scale, blue-scale), but these
+ * were not recorded. Instead we calculated the reference white (X,Y,Z) and
+ * recorded the chromaticity of this. The reference white (X,Y,Z) would have
+ * given all three of the scale factors since:
+ *
+ * color-C = color-c * color-scale
+ * white-C = red-C + green-C + blue-C
+ * = red-c*red-scale + green-c*green-scale + blue-c*blue-scale
+ *
+ * But cHRM records only white-x and white-y, so we have lost the white scale
+ * factor:
+ *
+ * white-C = white-c*white-scale
+ *
+ * To handle this the inverse transformation makes an arbitrary assumption
+ * about white-scale:
+ *
+ * Assume: white-Y = 1.0
+ * Hence: white-scale = 1/white-y
+ * Or: red-Y + green-Y + blue-Y = 1.0
+ *
+ * Notice the last statement of the assumption gives an equation in three of
+ * the nine values we want to calculate. 8 more equations come from the
+ * above routine as summarised at the top above (the chromaticity
+ * calculation):
+ *
+ * Given: color-x = color-X / (color-X + color-Y + color-Z)
+ * Hence: (color-x - 1)*color-X + color.x*color-Y + color.x*color-Z = 0
+ *
+ * This is 9 simultaneous equations in the 9 variables "color-C" and can be
+ * solved by Cramer's rule. Cramer's rule requires calculating 10 9x9 matrix
+ * determinants, however this is not as bad as it seems because only 28 of
+ * the total of 90 terms in the various matrices are non-zero. Nevertheless
+ * Cramer's rule is notoriously numerically unstable because the determinant
+ * calculation involves the difference of large, but similar, numbers. It is
+ * difficult to be sure that the calculation is stable for real world values
+ * and it is certain that it becomes unstable where the end points are close
+ * together.
+ *
+ * So this code uses the perhaps slightly less optimal but more
+ * understandable and totally obvious approach of calculating color-scale.
+ *
+ * This algorithm depends on the precision in white-scale and that is
+ * (1/white-y), so we can immediately see that as white-y approaches 0 the
+ * accuracy inherent in the cHRM chunk drops off substantially.
+ *
+ * libpng arithmetic: a simple inversion of the above equations
+ * ------------------------------------------------------------
+ *
+ * white_scale = 1/white-y
+ * white-X = white-x * white-scale
+ * white-Y = 1.0
+ * white-Z = (1 - white-x - white-y) * white_scale
+ *
+ * white-C = red-C + green-C + blue-C
+ * = red-c*red-scale + green-c*green-scale + blue-c*blue-scale
+ *
+ * This gives us three equations in (red-scale,green-scale,blue-scale) where
+ * all the coefficients are now known:
+ *
+ * red-x*red-scale + green-x*green-scale + blue-x*blue-scale
+ * = white-x/white-y
+ * red-y*red-scale + green-y*green-scale + blue-y*blue-scale = 1
+ * red-z*red-scale + green-z*green-scale + blue-z*blue-scale
+ * = (1 - white-x - white-y)/white-y
+ *
+ * In the last equation color-z is (1 - color-x - color-y) so we can add all
+ * three equations together to get an alternative third:
+ *
+ * red-scale + green-scale + blue-scale = 1/white-y = white-scale
+ *
+ * So now we have a Cramer's rule solution where the determinants are just
+ * 3x3 - far more tractible. Unfortunately 3x3 determinants still involve
+ * multiplication of three coefficients so we can't guarantee to avoid
+ * overflow in the libpng fixed point representation. Using Cramer's rule in
+ * floating point is probably a good choice here, but it's not an option for
+ * fixed point. Instead proceed to simplify the first two equations by
+ * eliminating what is likely to be the largest value, blue-scale:
+ *
+ * blue-scale = white-scale - red-scale - green-scale
+ *
+ * Hence:
+ *
+ * (red-x - blue-x)*red-scale + (green-x - blue-x)*green-scale =
+ * (white-x - blue-x)*white-scale
+ *
+ * (red-y - blue-y)*red-scale + (green-y - blue-y)*green-scale =
+ * 1 - blue-y*white-scale
+ *
+ * And now we can trivially solve for (red-scale,green-scale):
+ *
+ * green-scale =
+ * (white-x - blue-x)*white-scale - (red-x - blue-x)*red-scale
+ * -----------------------------------------------------------
+ * green-x - blue-x
+ *
+ * red-scale =
+ * 1 - blue-y*white-scale - (green-y - blue-y) * green-scale
+ * ---------------------------------------------------------
+ * red-y - blue-y
+ *
+ * Hence:
+ *
+ * red-scale =
+ * ( (green-x - blue-x) * (white-y - blue-y) -
+ * (green-y - blue-y) * (white-x - blue-x) ) / white-y
+ * -------------------------------------------------------------------------
+ * (green-x - blue-x)*(red-y - blue-y)-(green-y - blue-y)*(red-x - blue-x)
+ *
+ * green-scale =
+ * ( (red-y - blue-y) * (white-x - blue-x) -
+ * (red-x - blue-x) * (white-y - blue-y) ) / white-y
+ * -------------------------------------------------------------------------
+ * (green-x - blue-x)*(red-y - blue-y)-(green-y - blue-y)*(red-x - blue-x)
+ *
+ * Accuracy:
+ * The input values have 5 decimal digits of accuracy. The values are all in
+ * the range 0 < value < 1, so simple products are in the same range but may
+ * need up to 10 decimal digits to preserve the original precision and avoid
+ * underflow. Because we are using a 32-bit signed representation we cannot
+ * match this; the best is a little over 9 decimal digits, less than 10.
+ *
+ * The approach used here is to preserve the maximum precision within the
+ * signed representation. Because the red-scale calculation above uses the
+ * difference between two products of values that must be in the range -1..+1
+ * it is sufficient to divide the product by 7; ceil(100,000/32767*2). The
+ * factor is irrelevant in the calculation because it is applied to both
+ * numerator and denominator.
+ *
+ * Note that the values of the differences of the products of the
+ * chromaticities in the above equations tend to be small, for example for
+ * the sRGB chromaticities they are:
+ *
+ * red numerator: -0.04751
+ * green numerator: -0.08788
+ * denominator: -0.2241 (without white-y multiplication)
+ *
+ * The resultant Y coefficients from the chromaticities of some widely used
+ * color space definitions are (to 15 decimal places):
+ *

- * for applications, is an unsigned integer of the form xyyzz corresponding
- * to the source version x.y.z (leading zeros in y and z). Beta versions
- * were given the previous public release number plus a letter, until
- * version 1.0.6j; from then on they were given the upcoming public
- * release number plus "betaNN" or "rcNN".
- *
- * Binary incompatibility exists only when applications make direct access
- * to the info_ptr or png_ptr members through png.h, and the compiled
- * application is loaded with a different version of the library.
- *
- * DLLNUM will change each time there are forward or backward changes
- * in binary compatibility (e.g., when a new feature is added).
- *
- * See libpng-manual.txt or libpng.3 for more information. The PNG

- * Y2K compliance in libpng:
- * =========================
- *
- * September 27, 2012
- *
- * Since the PNG Development group is an ad-hoc body, we can't make
- * an official declaration.
- *
- * This is your unofficial assurance that libpng from version 0.71 and
- * upward through 1.5.13 are Y2K compliant. It is my belief that
- * earlier versions were also Y2K compliant.
- *
- * Libpng only has two year fields. One is a 2-byte unsigned integer
- * that will hold years up to 65535. The other holds the date in text
- * format, and will hold years up to 9999.
- *
- * The integer is
- * "png_uint_16 year" in png_time_struct.
- *
- * The string is
- * "char time_buffer[29]" in png_struct. This will be no
- * longer used in libpng-1.6.0 and will be removed from libpng-1.7.0.
- *
- * There are seven time-related functions:
- * png.c: png_convert_to_rfc_1123() in png.c
- * (formerly png_convert_to_rfc_1152() in error)
- * png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
- * png_convert_from_time_t() in pngwrite.c
- * png_get_tIME() in pngget.c
- * png_handle_tIME() in pngrutil.c, called in pngread.c
- * png_set_tIME() in pngset.c
- * png_write_tIME() in pngwutil.c, called in pngwrite.c
- *
- * All handle dates properly in a Y2K environment. The
- * png_convert_from_time_t() function calls gmtime() to convert from system
- * clock time, which returns (year - 1900), which we properly convert to
- * the full 4-digit year. There is a possibility that applications using
- * libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
- * function, or that they are incorrectly passing only a 2-digit year
- * instead of "year - 1900" into the png_convert_from_struct_tm() function,
- * but this is not under our control. The libpng documentation has always
- * stated that it works with 4-digit years, and the APIs have been
- * documented as such.
- *
- * The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned
- * integer to hold the year, and can hold years as large as 65535.
- *
- * zlib, upon which libpng depends, is also Y2K compliant. It contains
- * no date-related code.

-/* How the alpha channel is interpreted - this affects how the color channels of

- *
- * This has no effect on the way pixels are written into a PNG output
- * datastream. The color samples in a PNG datastream are never premultiplied
- * with the alpha samples.
- *
- * The default is to return data according to the PNG specification: the alpha
- * channel is a linear measure of the contribution of the pixel to the
- * corresponding composited pixel. The gamma encoded color channels must be
- * scaled according to the contribution and to do this it is necessary to undo
- * the encoding, scale the color values, perform the composition and reencode
- * the values. This is the 'PNG' mode.
- *
- * The alternative is to 'associate' the alpha with the color information by
- * storing color channel values that have been scaled by the alpha. The
- * advantage is that the color channels can be resampled (the image can be
- * scaled) in this form. The disadvantage is that normal practice is to store
- * linear, not (gamma) encoded, values and this requires 16-bit channels for
- * still images rather than the 8-bit channels that are just about sufficient if
- * gamma encoding is used. In addition all non-transparent pixel values,
- * including completely opaque ones, must be gamma encoded to produce the final
- * image. This is the 'STANDARD', 'ASSOCIATED' or 'PREMULTIPLIED' mode (the
- * latter being the two common names for associated alpha color channels.)
- *
- * Since it is not necessary to perform arithmetic on opaque color values so
- * long as they are not to be resampled and are in the final color space it is
- * possible to optimize the handling of alpha by storing the opaque pixels in
- * the PNG format (adjusted for the output color space) while storing partially
- * opaque pixels in the standard, linear, format. The accuracy required for
- * standard alpha composition is relatively low, because the pixels are
- * isolated, therefore typically the accuracy loss in storing 8-bit linear
- * values is acceptable. (This is not true if the alpha channel is used to
- * simulate transparency over large areas - use 16 bits or the PNG mode in
- * this case!) This is the 'OPTIMIZED' mode. For this mode a pixel is
- * treated as opaque only if the alpha value is equal to the maximum value.
- *
- * The final choice is to gamma encode the alpha channel as well. This is
- * broken because, in practice, no implementation that uses this choice
- * correctly undoes the encoding before handling alpha composition. Use this
- * choice only if other serious errors in the software or hardware you use
- * mandate it; the typical serious error is for dark halos to appear around
- * opaque areas of the composited PNG image because of arithmetic overflow.
- *

- * behind it. sRGB is defined to be approximated by a PNG gAMA chunk value of
- * 0.45455 (1/2.2) for PNG. The value implicitly includes any viewing
- * correction required to take account of any differences in the color
- * environment of the original scene and the intended display environment; the
- * value expresses how to *decode* the image for display, not how the original
- * data was *encoded*.
- *
- * sRGB provides a peg for the PNG standard by defining a viewing environment.
- * sRGB itself, and earlier TV standards, actually use a more complex transform
- * (a linear portion then a gamma 2.4 power law) than PNG can express. (PNG is
- * limited to simple power laws.) By saying that an image for direct display on
- * an sRGB conformant system should be stored with a gAMA chunk value of 45455
- * (11.3.3.2 and 11.3.3.5 of the ISO PNG specification) the PNG specification
- * makes it possible to derive values for other display systems and
- * environments.
- *
- * The Mac value is deduced from the sRGB based on an assumption that the actual
- * extra viewing correction used in early Mac display systems was implemented as
- * a power 1.45 lookup table.
- *
- * Any system where a programmable lookup table is used or where the behavior of
- * the final display device characteristics can be changed requires system
- * specific code to obtain the current characteristic. However this can be
- * difficult and most PNG gamma correction only requires an approximate value.
- *
- * By default, if png_set_alpha_mode() is not called, libpng assumes that all
- * values are unencoded, linear, values and that the output device also has a
- * linear characteristic. This is only very rarely correct - it is invariably
- * better to call png_set_alpha_mode() with PNG_DEFAULT_sRGB than rely on the
- * default if you don't know what the right answer is!
- *
- * The special value PNG_GAMMA_MAC_18 indicates an older Mac system (pre Mac OS
- * 10.6) which used a correction table to implement a somewhat lower gamma on an
- * otherwise sRGB system.
- *
- * Both these values are reserved (not simple gamma values) in order to allow
- * more precise correction internally in the future.
- *
- * NOTE: the following values can be passed to either the fixed or floating
- * point APIs, but the floating point API will also accept floating point
- * values.

-/* The following are examples of calls to png_set_alpha_mode to achieve the

- * premultiplication.
- *
- * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
- * This is the default libpng handling of the alpha channel - it is not
- * pre-multiplied into the color components. In addition the call states
- * that the output is for a sRGB system and causes all PNG files without gAMA
- * chunks to be assumed to be encoded using sRGB.
- *
- * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
- * In this case the output is assumed to be something like an sRGB conformant
- * display preceeded by a power-law lookup table of power 1.45. This is how
- * early Mac systems behaved.
- *
- * png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_GAMMA_LINEAR);
- * This is the classic Jim Blinn approach and will work in academic
- * environments where everything is done by the book. It has the shortcoming
- * of assuming that input PNG data with no gamma information is linear - this
- * is unlikely to be correct unless the PNG files where generated locally.
- * Most of the time the output precision will be so low as to show
- * significant banding in dark areas of the image.
- *
- * png_set_expand_16(pp);
- * png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_DEFAULT_sRGB);
- * This is a somewhat more realistic Jim Blinn inspired approach. PNG files
- * are assumed to have the sRGB encoding if not marked with a gamma value and
- * the output is always 16 bits per component. This permits accurate scaling
- * and processing of the data. If you know that your input PNG files were
- * generated locally you might need to replace PNG_DEFAULT_sRGB with the
- * correct value for your system.
- *
- * png_set_alpha_mode(pp, PNG_ALPHA_OPTIMIZED, PNG_DEFAULT_sRGB);
- * If you just need to composite the PNG image onto an existing background
- * and if you control the code that does this you can use the optimization
- * setting. In this case you just copy completely opaque pixels to the
- * output. For pixels that are not completely transparent (you just skip
- * those) you do the composition math using png_composite or png_composite_16
- * below then encode the resultant 8-bit or 16-bit values to match the output
- * encoding.
- *
- * Other cases
- * If neither the PNG nor the standard linear encoding work for you because
- * of the software or hardware you use then you have a big problem. The PNG
- * case will probably result in halos around the image. The linear encoding
- * will probably result in a washed out, too bright, image (it's actually too
- * contrasty.) Try the ALPHA_OPTIMIZED mode above - this will probably
- * substantially reduce the halos. Alternatively try:
- *
- * png_set_alpha_mode(pp, PNG_ALPHA_BROKEN, PNG_DEFAULT_sRGB);
- * This option will also reduce the halos, but there will be slight dark
- * halos round the opaque parts of the image where the background is light.
- * In the OPTIMIZED mode the halos will be light halos where the background
- * is dark. Take your pick - the halos are unavoidable unless you can get
- * your hardware/software fixed! (The OPTIMIZED approach is slightly
- * faster.)
- *
- * When the default gamma of PNG files doesn't match the output gamma.
- * If you have PNG files with no gamma information png_set_alpha_mode allows
- * you to provide a default gamma, but it also sets the ouput gamma to the
- * matching value. If you know your PNG files have a gamma that doesn't
- * match the output you can take advantage of the fact that
- * png_set_alpha_mode always sets the output gamma but only sets the PNG
- * default if it is not already set:
- *
- * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
- * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
- * The first call sets both the default and the output gamma values, the
- * second call overrides the output gamma without changing the default. This
- * is easier than achieving the same effect with png_set_gamma. You must use
- * PNG_ALPHA_PNG for the first call - internal checking in png_set_alpha will
- * fire if more than one call to png_set_alpha_mode and png_set_background is
- * made in the same read operation, however multiple calls with PNG_ALPHA_PNG
- * are ignored.

+ * PNG_LIBPNG_VER macro, which is not used within libpng but is available
+ * for applications, is an unsigned integer of the form xyyzz corresponding
+ * to the source version x.y.z (leading zeros in y and z). Beta versions
+ * were given the previous public release number plus a letter, until
+ * version 1.0.6j; from then on they were given the upcoming public
+ * release number plus "betaNN" or "rcNN".
+ *
+ * Binary incompatibility exists only when applications make direct access
+ * to the info_ptr or png_ptr members through png.h, and the compiled
+ * application is loaded with a different version of the library.
+ *
+ * DLLNUM will change each time there are forward or backward changes
+ * in binary compatibility (e.g., when a new feature is added).

+ * Y2K compliance in libpng:
+ * =========================
+ *
+ * December 22, 2014
+ *
+ * Since the PNG Development group is an ad-hoc body, we can't make
+ * an official declaration.
+ *
+ * This is your unofficial assurance that libpng from version 0.71 and
+ * upward through 1.6.16 are Y2K compliant. It is my belief that
+ * earlier versions were also Y2K compliant.
+ *
+ * Libpng only has two year fields. One is a 2-byte unsigned integer
+ * that will hold years up to 65535. The other, which is deprecated,
+ * holds the date in text format, and will hold years up to 9999.
+ *
+ * The integer is
+ * "png_uint_16 year" in png_time_struct.
+ *
+ * The string is
+ * "char time_buffer[29]" in png_struct. This is no longer used
+ * in libpng-1.6.x and will be removed from libpng-1.7.0.
+ *
+ * There are seven time-related functions:
+ * png.c: png_convert_to_rfc_1123_buffer() in png.c
+ * (formerly png_convert_to_rfc_1123() prior to libpng-1.5.x and
+ * png_convert_to_rfc_1152() in error prior to libpng-0.98)
+ * png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
+ * png_convert_from_time_t() in pngwrite.c
+ * png_get_tIME() in pngget.c
+ * png_handle_tIME() in pngrutil.c, called in pngread.c
+ * png_set_tIME() in pngset.c
+ * png_write_tIME() in pngwutil.c, called in pngwrite.c
+ *
+ * All handle dates properly in a Y2K environment. The
+ * png_convert_from_time_t() function calls gmtime() to convert from system
+ * clock time, which returns (year - 1900), which we properly convert to
+ * the full 4-digit year. There is a possibility that libpng applications
+ * are not passing 4-digit years into the png_convert_to_rfc_1123_buffer()
+ * function, or that they are incorrectly passing only a 2-digit year
+ * instead of "year - 1900" into the png_convert_from_struct_tm() function,
+ * but this is not under our control. The libpng documentation has always
+ * stated that it works with 4-digit years, and the APIs have been
+ * documented as such.
+ *
+ * The tIME chunk itself is also Y2K compliant. It uses a 2-byte unsigned
+ * integer to hold the year, and can hold years as large as 65535.
+ *
+ * zlib, upon which libpng depends, is also Y2K compliant. It contains
+ * no date-related code.

+ *
+ * png_set_expand_16(pp);
+ * png_set_alpha_mode(pp, PNG_ALPHA_STANDARD, PNG_DEFAULT_sRGB);
+ * This is a somewhat more realistic Jim Blinn inspired approach. PNG files
+ * are assumed to have the sRGB encoding if not marked with a gamma value and
+ * the output is always 16 bits per component. This permits accurate scaling
+ * and processing of the data. If you know that your input PNG files were

+ * output. For pixels that are not completely transparent (you just skip
+ * those) you do the composition math using png_composite or png_composite_16
+ * below then encode the resultant 8-bit or 16-bit values to match the output
+ * encoding.
+ *
+ * Other cases
+ * If neither the PNG nor the standard linear encoding work for you because
+ * of the software or hardware you use then you have a big problem. The PNG
+ * case will probably result in halos around the image. The linear encoding
+ * will probably result in a washed out, too bright, image (it's actually too
+ * contrasty.) Try the ALPHA_OPTIMIZED mode above - this will probably
+ * substantially reduce the halos. Alternatively try:
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_BROKEN, PNG_DEFAULT_sRGB);
+ * This option will also reduce the halos, but there will be slight dark
+ * halos round the opaque parts of the image where the background is light.
+ * In the OPTIMIZED mode the halos will be light halos where the background
+ * is dark. Take your pick - the halos are unavoidable unless you can get
+ * your hardware/software fixed! (The OPTIMIZED approach is slightly
+ * faster.)
+ *
+ * When the default gamma of PNG files doesn't match the output gamma.
+ * If you have PNG files with no gamma information png_set_alpha_mode allows
+ * you to provide a default gamma, but it also sets the ouput gamma to the
+ * matching value. If you know your PNG files have a gamma that doesn't
+ * match the output you can take advantage of the fact that
+ * png_set_alpha_mode always sets the output gamma but only sets the PNG
+ * default if it is not already set:
+ *
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_DEFAULT_sRGB);
+ * png_set_alpha_mode(pp, PNG_ALPHA_PNG, PNG_GAMMA_MAC);
+ * The first call sets both the default and the output gamma values, the
+ * second call overrides the output gamma without changing the default. This
+ * is easier than achieving the same effect with png_set_gamma. You must use
+ * PNG_ALPHA_PNG for the first call - internal checking in png_set_alpha will
+ * fire if more than one call to png_set_alpha_mode and png_set_background is
+ * made in the same read operation, however multiple calls with PNG_ALPHA_PNG

+ *
+ * NOTE: prior to 1.6.0 the handling specified for particular chunks on read was
+ * ignored and the default was used, the per-chunk setting only had an effect on
+ * write. If you wish to have chunk-specific handling on read in code that must
+ * work on earlier versions you must use a user chunk callback to specify the
+ * desired handling (keep or discard.)
+ *
+ * The 'keep' parameter is a PNG_HANDLE_CHUNK_ value as listed below. The
+ * parameter is interpreted as follows:
+ *
+ * READ:
+ * PNG_HANDLE_CHUNK_AS_DEFAULT:
+ * Known chunks: do normal libpng processing, do not keep the chunk (but
+ * see the comments below about PNG_HANDLE_AS_UNKNOWN_SUPPORTED)
+ * Unknown chunks: for a specific chunk use the global default, when used
+ * as the default discard the chunk data.
+ * PNG_HANDLE_CHUNK_NEVER:
+ * Discard the chunk data.
+ * PNG_HANDLE_CHUNK_IF_SAFE:
+ * Keep the chunk data if the chunk is not critical else raise a chunk
+ * error.
+ * PNG_HANDLE_CHUNK_ALWAYS:
+ * Keep the chunk data.
+ *
+ * If the chunk data is saved it can be retrieved using png_get_unknown_chunks,
+ * below. Notice that specifying "AS_DEFAULT" as a global default is equivalent
+ * to specifying "NEVER", however when "AS_DEFAULT" is used for specific chunks
+ * it simply resets the behavior to the libpng default.
+ *
+ * INTERACTION WTIH USER CHUNK CALLBACKS:
+ * The per-chunk handling is always used when there is a png_user_chunk_ptr
+ * callback and the callback returns 0; the chunk is then always stored *unless*
+ * it is critical and the per-chunk setting is other than ALWAYS. Notice that
+ * the global default is *not* used in this case. (In effect the per-chunk
+ * value is incremented to at least IF_SAFE.)
+ *
+ * IMPORTANT NOTE: this behavior will change in libpng 1.7 - the global and
+ * per-chunk defaults will be honored. If you want to preserve the current
+ * behavior when your callback returns 0 you must set PNG_HANDLE_CHUNK_IF_SAFE
+ * as the default - if you don't do this libpng 1.6 will issue a warning.
+ *
+ * If you want unhandled unknown chunks to be discarded in libpng 1.6 and
+ * earlier simply return '1' (handled).
+ *
+ * PNG_HANDLE_AS_UNKNOWN_SUPPORTED:
+ * If this is *not* set known chunks will always be handled by libpng and
+ * will never be stored in the unknown chunk list. Known chunks listed to
+ * png_set_keep_unknown_chunks will have no effect. If it is set then known
+ * chunks listed with a keep other than AS_DEFAULT will *never* be processed
+ * by libpng, in addition critical chunks must either be processed by the
+ * callback or saved.
+ *
+ * The IHDR and IEND chunks must not be listed. Because this turns off the
+ * default handling for chunks that would otherwise be recognized the
+ * behavior of libpng transformations may well become incorrect!
+ *
+ * WRITE:
+ * When writing chunks the options only apply to the chunks specified by
+ * png_set_unknown_chunks (below), libpng will *always* write known chunks
+ * required by png_set_ calls and will always write the core critical chunks
+ * (as required for PLTE).
+ *
+ * Each chunk in the png_set_unknown_chunks list is looked up in the
+ * png_set_keep_unknown_chunks list to find the keep setting, this is then
+ * interpreted as follows:
+ *
+ * PNG_HANDLE_CHUNK_AS_DEFAULT:
+ * Write safe-to-copy chunks and write other chunks if the global
+ * default is set to _ALWAYS, otherwise don't write this chunk.
+ * PNG_HANDLE_CHUNK_NEVER:
+ * Do not write the chunk.
+ * PNG_HANDLE_CHUNK_IF_SAFE:
+ * Write the chunk if it is safe-to-copy, otherwise do not write it.
+ * PNG_HANDLE_CHUNK_ALWAYS:
+ * Write the chunk.
+ *
+ * Note that the default behavior is effectively the opposite of the read case -
+ * in read unknown chunks are not stored by default, in write they are written
+ * by default. Also the behavior of PNG_HANDLE_CHUNK_IF_SAFE is very different
+ * - on write the safe-to-copy bit is checked, on read the critical bit is
+ * checked and on read if the chunk is critical an error will be raised.
+ *
+ * num_chunks:
+ * ===========
+ * If num_chunks is positive, then the "keep" parameter specifies the manner
+ * for handling only those chunks appearing in the chunk_list array,
+ * otherwise the chunk list array is ignored.
+ *
+ * If num_chunks is 0 the "keep" parameter specifies the default behavior for
+ * unknown chunks, as described above.
+ *
+ * If num_chunks is negative, then the "keep" parameter specifies the manner

+ * SIMPLIFIED API
+ *******************************************************************************
+ *
+ * Please read the documentation in libpng-manual.txt (TODO: write said
+ * documentation) if you don't understand what follows.
+ *
+ * The simplified API hides the details of both libpng and the PNG file format
+ * itself. It allows PNG files to be read into a very limited number of
+ * in-memory bitmap formats or to be written from the same formats. If these
+ * formats do not accomodate your needs then you can, and should, use the more
+ * sophisticated APIs above - these support a wide variety of in-memory formats
+ * and a wide variety of sophisticated transformations to those formats as well
+ * as a wide variety of APIs to manipulate ancillary information.
+ *
+ * To read a PNG file using the simplified API:
+ *
+ * 1) Declare a 'png_image' structure (see below) on the stack and set the
+ * version field to PNG_IMAGE_VERSION.
+ * 2) Call the appropriate png_image_begin_read... function.
+ * 3) Set the png_image 'format' member to the required sample format.
+ * 4) Allocate a buffer for the image and, if required, the color-map.
+ * 5) Call png_image_finish_read to read the image and, if required, the
+ * color-map into your buffers.
+ *
+ * There are no restrictions on the format of the PNG input itself; all valid
+ * color types, bit depths, and interlace methods are acceptable, and the
+ * input image is transformed as necessary to the requested in-memory format
+ * during the png_image_finish_read() step. The only caveat is that if you
+ * request a color-mapped image from a PNG that is full-color or makes
+ * complex use of an alpha channel the transformation is extremely lossy and the
+ * result may look terrible.
+ *
+ * To write a PNG file using the simplified API:
+ *
+ * 1) Declare a 'png_image' structure on the stack and memset() it to all zero.
+ * 2) Initialize the members of the structure that describe the image, setting
+ * the 'format' member to the format of the image samples.
+ * 3) Call the appropriate png_image_write... function with a pointer to the
+ * image and, if necessary, the color-map to write the PNG data.
+ *
+ * png_image is a structure that describes the in-memory format of an image
+ * when it is being read or defines the in-memory format of an image that you
+ * need to write:

+ * 2: A gray/luminance channel and an alpha channel (GA).
+ * 3: Three red, green, blue color channels (RGB).
+ * 4: Three color channels and an alpha channel (RGBA).
+ *
+ * The components are encoded in one of two ways:
+ *
+ * a) As a small integer, value 0..255, contained in a single byte. For the
+ * alpha channel the original value is simply value/255. For the color or
+ * luminance channels the value is encoded according to the sRGB specification
+ * and matches the 8-bit format expected by typical display devices.
+ *
+ * The color/gray channels are not scaled (pre-multiplied) by the alpha
+ * channel and are suitable for passing to color management software.
+ *
+ * b) As a value in the range 0..65535, contained in a 2-byte integer. All
+ * channels can be converted to the original value by dividing by 65535; all
+ * channels are linear. Color channels use the RGB encoding (RGB end-points) of
+ * the sRGB specification. This encoding is identified by the
+ * PNG_FORMAT_FLAG_LINEAR flag below.
+ *
+ * When the simplified API needs to convert between sRGB and linear colorspaces,
+ * the actual sRGB transfer curve defined in the sRGB specification (see the
+ * article at http://en.wikipedia.org/wiki/SRGB) is used, not the gamma=1/2.2
+ * approximation used elsewhere in libpng.
+ *
+ * When an alpha channel is present it is expected to denote pixel coverage
+ * of the color or luminance channels and is returned as an associated alpha
+ * channel: the color/gray channels are scaled (pre-multiplied) by the alpha
+ * value.
+ *
+ * The samples are either contained directly in the image data, between 1 and 8
+ * bytes per pixel according to the encoding, or are held in a color-map indexed
+ * by bytes in the image data. In the case of a color-map the color-map entries
+ * are individual samples, encoded as above, and the image data has one byte per
+ * pixel to select the relevant sample from the color-map.
+ */

+ *
+ * A format is built up using single bit flag values. All combinations are
+ * valid. Formats can be built up from the flag values or you can use one of
+ * the predefined values below. When testing formats always use the FORMAT_FLAG
+ * macros to test for individual features - future versions of the library may

+ *
+ * When reading or writing color-mapped images the format should be set to the

-/* Function calling conventions.
- * =============================
- * Normally it is not necessary to specify to the compiler how to call
- * a function - it just does it - however on x86 systems derived from
- * Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
- * and some others) there are multiple ways to call a function and the
- * default can be changed on the compiler command line. For this reason
- * libpng specifies the calling convention of every exported function and
- * every function called via a user supplied function pointer. This is
- * done in this file by defining the following macros:
- *
- * PNGAPI Calling convention for exported functions.
- * PNGCBAPI Calling convention for user provided (callback) functions.
- * PNGCAPI Calling convention used by the ANSI-C library (required
- * for longjmp callbacks and sometimes used internally to
- * specify the calling convention for zlib).
- *
- * These macros should never be overridden. If it is necessary to
- * change calling convention in a private build this can be done
- * by setting PNG_API_RULE (which defaults to 0) to one of the values
- * below to select the correct 'API' variants.
- *
- * PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
- * This is correct in every known environment.
- * PNG_API_RULE=1 Use the operating system convention for PNGAPI and
- * the 'C' calling convention (from PNGCAPI) for
- * callbacks (PNGCBAPI). This is no longer required
- * in any known environment - if it has to be used
- * please post an explanation of the problem to the
- * libpng mailing list.
- *
- * These cases only differ if the operating system does not use the C
- * calling convention, at present this just means the above cases
- * (x86 DOS/Windows sytems) and, even then, this does not apply to
- * Cygwin running on those systems.
- *
- * Note that the value must be defined in pnglibconf.h so that what
- * the application uses to call the library matches the conventions
- * set when building the library.
- */
-
-/* Symbol export
- * =============
- * When building a shared library it is almost always necessary to tell
- * the compiler which symbols to export. The png.h macro 'PNG_EXPORT'
- * is used to mark the symbols. On some systems these symbols can be
- * extracted at link time and need no special processing by the compiler,
- * on other systems the symbols are flagged by the compiler and just
- * the declaration requires a special tag applied (unfortunately) in a
- * compiler dependent way. Some systems can do either.
- *
- * A small number of older systems also require a symbol from a DLL to
- * be flagged to the program that calls it. This is a problem because
- * we do not know in the header file included by application code that
- * the symbol will come from a shared library, as opposed to a statically
- * linked one. For this reason the application must tell us by setting
- * the magic flag PNG_USE_DLL to turn on the special processing before
- * it includes png.h.
- *
- * Four additional macros are used to make this happen:
- *
- * PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
- * the build or imported if PNG_USE_DLL is set - compiler
- * and system specific.
- *
- * PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
- * 'type', compiler specific.
- *
- * PNG_DLL_EXPORT Set to the magic to use during a libpng build to
- * make a symbol exported from the DLL. Not used in the
- * public header files; see pngpriv.h for how it is used
- * in the libpng build.
- *
- * PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
- * from a DLL - used to define PNG_IMPEXP when
- * PNG_USE_DLL is set.
- */
-
-/* System specific discovery.
- * ==========================
- * This code is used at build time to find PNG_IMPEXP, the API settings
- * and PNG_EXPORT_TYPE(), it may also set a macro to indicate the DLL

+ * =============================
+ * Normally it is not necessary to specify to the compiler how to call
+ * a function - it just does it - however on x86 systems derived from
+ * Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
+ * and some others) there are multiple ways to call a function and the
+ * default can be changed on the compiler command line. For this reason
+ * libpng specifies the calling convention of every exported function and
+ * every function called via a user supplied function pointer. This is
+ * done in this file by defining the following macros:
+ *
+ * PNGAPI Calling convention for exported functions.
+ * PNGCBAPI Calling convention for user provided (callback) functions.
+ * PNGCAPI Calling convention used by the ANSI-C library (required
+ * for longjmp callbacks and sometimes used internally to
+ * specify the calling convention for zlib).
+ *
+ * These macros should never be overridden. If it is necessary to
+ * change calling convention in a private build this can be done
+ * by setting PNG_API_RULE (which defaults to 0) to one of the values
+ * below to select the correct 'API' variants.
+ *
+ * PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
+ * This is correct in every known environment.
+ * PNG_API_RULE=1 Use the operating system convention for PNGAPI and
+ * the 'C' calling convention (from PNGCAPI) for
+ * callbacks (PNGCBAPI). This is no longer required
+ * in any known environment - if it has to be used
+ * please post an explanation of the problem to the
+ * libpng mailing list.
+ *
+ * These cases only differ if the operating system does not use the C
+ * calling convention, at present this just means the above cases
+ * (x86 DOS/Windows sytems) and, even then, this does not apply to
+ * Cygwin running on those systems.
+ *
+ * Note that the value must be defined in pnglibconf.h so that what
+ * the application uses to call the library matches the conventions
+ * set when building the library.
+ */
+
+/* Symbol export
+ * =============
+ * When building a shared library it is almost always necessary to tell
+ * the compiler which symbols to export. The png.h macro 'PNG_EXPORT'
+ * is used to mark the symbols. On some systems these symbols can be
+ * extracted at link time and need no special processing by the compiler,
+ * on other systems the symbols are flagged by the compiler and just
+ * the declaration requires a special tag applied (unfortunately) in a
+ * compiler dependent way. Some systems can do either.
+ *
+ * A small number of older systems also require a symbol from a DLL to
+ * be flagged to the program that calls it. This is a problem because
+ * we do not know in the header file included by application code that
+ * the symbol will come from a shared library, as opposed to a statically
+ * linked one. For this reason the application must tell us by setting
+ * the magic flag PNG_USE_DLL to turn on the special processing before
+ * it includes png.h.
+ *
+ * Four additional macros are used to make this happen:
+ *
+ * PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
+ * the build or imported if PNG_USE_DLL is set - compiler
+ * and system specific.
+ *
+ * PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
+ * 'type', compiler specific.
+ *
+ * PNG_DLL_EXPORT Set to the magic to use during a libpng build to
+ * make a symbol exported from the DLL. Not used in the
+ * public header files; see pngpriv.h for how it is used
+ * in the libpng build.
+ *
+ * PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
+ * from a DLL - used to define PNG_IMPEXP when
+ * PNG_USE_DLL is set.
+ */
+
+/* System specific discovery.
+ * ==========================
+ * This code is used at build time to find PNG_IMPEXP, the API settings

- /* png_info is a structure that holds the information in a PNG file so
- * that the application can find out the characteristics of the image.
- * If you are reading the file, this structure will tell you what is
- * in the PNG file. If you are writing the file, fill in the information
- * you want to put into the PNG file, using png_set_*() functions, then
- * call png_write_info().
- *
- * The names chosen should be very close to the PNG specification, so
- * consult that document for information about the meaning of each field.
- *
- * With libpng < 0.95, it was only possible to directly set and read the
- * the values in the png_info_struct, which meant that the contents and
- * order of the values had to remain fixed. With libpng 0.95 and later,
- * however, there are now functions that abstract the contents of
- * png_info_struct from the application, so this makes it easier to use
- * libpng with dynamic libraries, and even makes it possible to use
- * libraries that don't have all of the libpng ancillary chunk-handing
- * functionality. In libpng-1.5.0 this was moved into a separate private
- * file that is not visible to applications.
- *
- * The following members may have allocated storage attached that should be
- * cleaned up before the structure is discarded: palette, trans, text,
- * pcal_purpose, pcal_units, pcal_params, hist, iccp_name, iccp_profile,
- * splt_palettes, scal_unit, row_pointers, and unknowns. By default, these
- * are automatically freed when the info structure is deallocated, if they were
- * allocated internally by libpng. This behavior can be changed by means
- * of the png_data_freer() function.
- *
- * More allocation details: all the chunk-reading functions that
- * change these members go through the corresponding png_set_*
- * functions. A function to clear these members is available: see
- * png_free_data(). The png_set_* functions do not depend on being
- * able to point info structure members to any of the storage they are
- * passed (they make their own copies), EXCEPT that the png_set_text
- * functions use the same storage passed to them in the text_ptr or
- * itxt_ptr structure argument, and the png_set_rows and png_set_unknowns
- * functions do not make their own copies.

+ /* png_info is a structure that holds the information in a PNG file so
+ * that the application can find out the characteristics of the image.
+ * If you are reading the file, this structure will tell you what is
+ * in the PNG file. If you are writing the file, fill in the information
+ * you want to put into the PNG file, using png_set_*() functions, then
+ * call png_write_info().
+ *
+ * The names chosen should be very close to the PNG specification, so
+ * consult that document for information about the meaning of each field.
+ *
+ * With libpng < 0.95, it was only possible to directly set and read the
+ * the values in the png_info_struct, which meant that the contents and
+ * order of the values had to remain fixed. With libpng 0.95 and later,
+ * however, there are now functions that abstract the contents of
+ * png_info_struct from the application, so this makes it easier to use
+ * libpng with dynamic libraries, and even makes it possible to use
+ * libraries that don't have all of the libpng ancillary chunk-handing
+ * functionality. In libpng-1.5.0 this was moved into a separate private
+ * file that is not visible to applications.
+ *
+ * The following members may have allocated storage attached that should be
+ * cleaned up before the structure is discarded: palette, trans, text,
+ * pcal_purpose, pcal_units, pcal_params, hist, iccp_name, iccp_profile,
+ * splt_palettes, scal_unit, row_pointers, and unknowns. By default, these
+ * are automatically freed when the info structure is deallocated, if they were
+ * allocated internally by libpng. This behavior can be changed by means
+ * of the png_data_freer() function.
+ *
+ * More allocation details: all the chunk-reading functions that
+ * change these members go through the corresponding png_set_*
+ * functions. A function to clear these members is available: see
+ * png_free_data(). The png_set_* functions do not depend on being
+ * able to point info structure members to any of the storage they are
+ * passed (they make their own copies), EXCEPT that the png_set_text
+ * functions use the same storage passed to them in the text_ptr or
+ * itxt_ptr structure argument, and the png_set_rows and png_set_unknowns
+ * functions do not make their own copies.

-/* From Andreas Dilger e-mail to png-implement, 26 March 1998:
- *
- * In most cases, the "simple transparency" should be done prior to doing
- * gray-to-RGB, or you will have to test 3x as many bytes to check if a
- * pixel is transparent. You would also need to make sure that the
- * transparency information is upgraded to RGB.
- *
- * To summarize, the current flow is:
- * - Gray + simple transparency -> compare 1 or 2 gray bytes and composite
- * with background "in place" if transparent,
- * convert to RGB if necessary
- * - Gray + alpha -> composite with gray background and remove alpha bytes,
- * convert to RGB if necessary
- *
- * To support RGB backgrounds for gray images we need:
- * - Gray + simple transparency -> convert to RGB + simple transparency,
- * compare 3 or 6 bytes and composite with
- * background "in place" if transparent
- * (3x compare/pixel compared to doing
- * composite with gray bkgrnd)
- * - Gray + alpha -> convert to RGB + alpha, composite with background and
- * remove alpha bytes (3x float
- * operations/pixel compared with composite
- * on gray background)
- *
- * Greg's change will do this. The reason it wasn't done before is for
- * performance, as this increases the per-pixel operations. If we would check
- * in advance if the background was gray or RGB, and position the gray-to-RGB
- * transform appropriately, then it would save a lot of work/time.

- * Poynton's current link (as of January 2003 through July 2011):
- * <http://www.poynton.com/notes/colour_and_gamma/>
- * has changed the numbers slightly:
- *
- * Y = 0.2126*R + 0.7152*G + 0.0722*B
- *
- * which can be expressed with integers as
- *
- * Y = (6966 * R + 23436 * G + 2366 * B)/32768
- *
- * Historically, however, libpng uses numbers derived from the ITU-R Rec 709
- * end point chromaticities and the D65 white point. Depending on the
- * precision used for the D65 white point this produces a variety of different
- * numbers, however if the four decimal place value used in ITU-R Rec 709 is
- * used (0.3127,0.3290) the Y calculation would be:
- *
- * Y = (6968 * R + 23435 * G + 2366 * B)/32768
- *
- * While this is correct the rounding results in an overflow for white, because
- * the sum of the rounded coefficients is 32769, not 32768. Consequently
- * libpng uses, instead, the closest non-overflowing approximation:
- *
- * Y = (6968 * R + 23434 * G + 2366 * B)/32768
- *
- * Starting with libpng-1.5.5, if the image being converted has a cHRM chunk
- * (including an sRGB chunk) then the chromaticities are used to calculate the
- * coefficients. See the chunk handling in pngrutil.c for more information.
- *
- * In all cases the calculation is to be done in a linear colorspace. If no
- * gamma information is available to correct the encoding of the original RGB
- * values this results in an implicit assumption that the original PNG RGB
- * values were linear.
- *
- * Other integer coefficents can be used via png_set_rgb_to_gray(). Because
- * the API takes just red and green coefficients the blue coefficient is
- * calculated to make the sum 32768. This will result in different rounding
- * to that used above.

+ * has changed the numbers slightly:
+ *
+ * Y = 0.2126*R + 0.7152*G + 0.0722*B
+ *
+ * which can be expressed with integers as
+ *
+ * Y = (6966 * R + 23436 * G + 2366 * B)/32768
+ *
+ * Historically, however, libpng uses numbers derived from the ITU-R Rec 709
+ * end point chromaticities and the D65 white point. Depending on the
+ * precision used for the D65 white point this produces a variety of different
+ * numbers, however if the four decimal place value used in ITU-R Rec 709 is
+ * used (0.3127,0.3290) the Y calculation would be:
+ *
+ * Y = (6968 * R + 23435 * G + 2366 * B)/32768
+ *
+ * While this is correct the rounding results in an overflow for white, because
+ * the sum of the rounded coefficients is 32769, not 32768. Consequently
+ * libpng uses, instead, the closest non-overflowing approximation:
+ *
+ * Y = (6968 * R + 23434 * G + 2366 * B)/32768
+ *
+ * Starting with libpng-1.5.5, if the image being converted has a cHRM chunk
+ * (including an sRGB chunk) then the chromaticities are used to calculate the
+ * coefficients. See the chunk handling in pngrutil.c for more information.
+ *
+ * In all cases the calculation is to be done in a linear colorspace. If no
+ * gamma information is available to correct the encoding of the original RGB
+ * values this results in an implicit assumption that the original PNG RGB
+ * values were linear.
+ *
+ * Other integer coefficents can be used via png_set_rgb_to_gray(). Because
+ * the API takes just red and green coefficients the blue coefficient is
+ * calculated to make the sum 32768. This will result in different rounding
+ * to that used above.

+ *
+ * In most cases, the "simple transparency" should be done prior to doing
+ * gray-to-RGB, or you will have to test 3x as many bytes to check if a
+ * pixel is transparent. You would also need to make sure that the
+ * transparency information is upgraded to RGB.
+ *
+ * To summarize, the current flow is:
+ * - Gray + simple transparency -> compare 1 or 2 gray bytes and composite
+ * with background "in place" if transparent,
+ * convert to RGB if necessary
+ * - Gray + alpha -> composite with gray background and remove alpha bytes,
+ * convert to RGB if necessary
+ *
+ * To support RGB backgrounds for gray images we need:
+ * - Gray + simple transparency -> convert to RGB + simple transparency,
+ * compare 3 or 6 bytes and composite with
+ * background "in place" if transparent
+ * (3x compare/pixel compared to doing
+ * composite with gray bkgrnd)
+ * - Gray + alpha -> convert to RGB + alpha, composite with background and
+ * remove alpha bytes (3x float
+ * operations/pixel compared with composite
+ * on gray background)
+ *
+ * Greg's change will do this. The reason it wasn't done before is for
+ * performance, as this increases the per-pixel operations. If we would check
+ * in advance if the background was gray or RGB, and position the gray-to-RGB
+ * transform appropriately, then it would save a lot of work/time.

+ Camera multipliers are now extracted correctly even if black is not 0
+
+ * Better source compatibility with Mac OS X compilation
+
+ * Better source compatibility with Win32 compilation
+
+ * DNG without Compression tag assumed uncompressed
+
+ * Better X3F-tools based Foveon support:
+ - new Foveon metadata parser based on X3F-tools. So, if LibRaw compiled
+ without demosaic-pack-GPL2, then no dcraw Foveon code used.
+ - Support for Medium resolution RAWs from DPx Merrill and SD1 cameras.
+ RAW data extracted as is (4800x1600 pixels), aspect ratio is set to
+ 0.5, so these RAWs are processed to full-size 4800x3200 RGB.
+ - Support for Foveon thumbnail extraction. Only JPEG and bitmap
+ thumbnails extracted, but 'foveon' (RAW) thumbnails are really not used
+ in production cameras.
+ - New imgdata.params.force_foveon_x3f flag
+ Forces use of x3f-tools based code for Foveon processing if LibRaw
+ compiled with demosaic-pack-GPL2 (and does nothing if LibRaw compiled
+ without this pack).
+ New flag -disadcf added to dcraw_emu sample to use this flag.
+ - LibRaw do not calls exit() on broken Foveon files.
+
+ * API/ABI changed, so all code using LibRaw should be recompiled.
+
+ * LibRaw 0.16.0-Alpha3

+
+ * Support for Foveon sensor based on X3F code by Roland Karlsson
+ BSD-like license, so included in main LibRaw code.
+ No 'foveon intepolation', so no way to get good colors from
+ old Sigma cameras (SD9, SD14, Polaroid x530). For modern Foveon cameras
+ one may try to create ICC profile (not supplied).
+
+ TODO: thumbnail extraction, fast cancelation
+
+ Old foveon_*_load_raw (from dcraw) code is used if compiled with
+ LIBRAW_DEMOSAIC_PACK_GPL2
+
+ * API Changes:
+
+ + New parameters in imgdata.params:
+ - imgdata.params.no_interpolation - disables interpolation step in
+ LibRaw::dcraw_process() call.
+ - imgdata.params.no_auto_scale - disables call to scale_colors() in
+ LibRaw::dcraw_process() call.
+ - imgdata.params.sraw_ycc - disables Canon sRAW YCbCr to RGB conversion
+ in LibRaw::unpack() call (use for RAW analyzers
+
+ + New Fuji X-Trans handling:
+ - imgdata.iparams.filters value is now 9 for Fuji X-Trans (instead of 2)
+ - imgdata.iparams.xtrans[6][6] matrix contains row/col to color mapping
+ for Fuji X-Trans sensor.
+
+ + LibRaw::setCancelFlag() - use for fast decoder termination
+
+ + LibRaw_abstract_datastream::make_byte_buffer() call is not needed more.
+
+ + New demosaic code: DHT Demosaic by Anton Petrusevich
+ Set params.user_qual=11 to use.
+
+ + New demosaic code: Modified AHD Demosaic by Anton Petrusevich
+ Set params.user_qual=12 to use.
+
+ + New C-API call libraw_COLOR(libraw_data_t *t, int row,int col)
+ (so LibRaw::COLOR(row,col) exposed to C-API users)
+
+ * Removed faster lossless jpeg decoder ported from RawSpeed library
+ some years ago. Build LibRaw with RawSpeed to get fast decoding.
+
+ * Fixed decoding error for some Canon sRAW files.
+
+ * Disabled RawSpeed's bad pixel processing if RawSpeed used.
+
+ * EOS M and EOS 70D added to unique Canon ID table
+
+ * Canon EOS model name normalized by unique ID table
+
+ * Backported 0.15.4 input data checks
+
+ * Support for CMake builds
+
+ * Updated RawSpeed supported camera list
+
+ * Internals changed, so all code using LibRaw should be recompiled.
+
+ * LibRaw 0.16.0-Alpha1
+
+2013-05-23 Alex Tutubalin <lexa at lexa.ru>
+
+ LibRaw 0.15-Release

+API changes:
+ 1. dcraw_process() can now be called several times with different parameters
+ without re-opening and unpacking the file for second and consecutive
+ calls to dcraw_process
+
+ 2. deleted (nobody uses those)
+ - LibRaw::dcraw_document_mode_processing (and respective C-API)
+ - imgdata.color.color_flags data field
+
+ 3. LibRaw::unpack() now decodes data into different buffers, the buffer
+ depends on the raw data type
+ - imgdata.rawdata.raw_image - 1 color component per pixel,
+ for b/w and Bayer type sensors
+ - imgdata.rawdata.color3_image - 3 color components per pixel,
+ sRAW/mRAW files, RawSpeed decoding
+ - imgdata.rawdata.color4_image - 4 components per pixel, the 4th
+ component can be void
+
+ 4. Support for compiling with RawSpeed library, http://rawstudio.org/blog/?p=800
+ details are in README.RawSpeed
+
+ 5. Suppression of banding
+
+ 6. New API calls
+ - recycle_datastream(),
+ - open_file(wchar_t*) (Win32)

+=== Notes for LibRaw contributor ===
+
+0. Repository
+ LibRaw public repository is located on GitHub
+ URL:
+ http://github.com/LibRaw/LibRaw - main page
+ git://github.com/LibRaw/LibRaw.git - git URL
+
+If you wish to participate in LibRaw development please use GitHub fork.
+
+1. Some files in internal/ folder are generated from dcraw/dcraw.c file
+ by simple preprocessor internal/preprocess.pl (you need perl to run it)
+
+ dcraw/dcraw.c is a *patched* dcraw (and foveon processng code is removed
+ due to copyright).
+
+ 'Official' dcraw.c changes are tracked by LibRaw team and merged to
+ head revision at regular basis.
+
+ So, if you want to change code in internal/*.cpp files you need to change
+ dcraw/dcraw.c (and run make)
+
+2. For developer's work use Makefile from GitHub
+ It contains rules to re-generate
+ internal/*cpp from dcraw/dcraw.c
+
+3. LibRaw distribution files are prepared by ./mkdist.sh script
+ This script
+ - regenerates internal/*cpp without #line directives
+ - generates ./configure script from autotools stuff
+ - removes developer Makefile
+ - fetches 'Official' dcraw.c from Dave Coffin's site
+ - removes .PSD files from doc/
+ - removes itself
+
+3. Please do not use ./configure script in development enviroment.
+ This script generates Makefile from ./Makefile.in for use in production.
+ The generated Makefile does not contain section to build internal/*
+ from dcraw/dcraw.c
+
+Feel free to contact us (info at libraw.org or Contact form on www.libraw.org) if
+you have any questions or suggestions.

+<A NAME="lbAE"> </A>
+<H2>GENERAL OPTIONS</H2>
+
+<DL COMPACT>
+<DT><B>-v</B>
+
+<DD>
+Print verbose messages, not just warnings and errors.
+<DT><B>-c</B>
+
+<DD>
+Write decoded images or thumbnails to standard output.
+<DT><B>-e</B>
+
+<DD>
+Extract the camera-generated thumbnail, not the raw image.
+You'll get either a JPEG or a PPM file, depending on the camera.
+<DT><B>-z</B>
+
+<DD>
+Change the access and modification times of an AVI, JPEG, TIFF or raw
+file to when the photo was taken, assuming that the camera clock
+was set to Universal Time.
+<DT><B>-i</B>
+
+<DD>
+Identify files but don't decode them.
+Exit status is 0 if
+<B>dcraw</B>
+
+can decode the last file, 1 if it can't.
+<B>-i -v</B>
+
+shows metadata.
+<DT><B></B>
+
+<DD>
+<B>dcraw</B>
+
+cannot decode JPEG files!!
+</DL>
+<A NAME="lbAF"> </A>
+<H2>REPAIR OPTIONS</H2>
+
+<DL COMPACT>
+<DT><B>-I</B>
+
+<DD>
+Read the raw pixels from standard input in CPU byte order with
+no header. Use
+<B>dcraw -E -4</B>
+
+to get the raw pixel values.
+<DT><B>-P deadpixels.txt</B>
+
+<DD>
+Read the dead pixel list from this file instead of ".badpixels".
+See
+<B>FILES</B>
+
+for a description of the format.
+<DT><B>-K darkframe.pgm</B>
+
+<DD>
+Subtract a dark frame from the raw data. To generate a
+dark frame, shoot a raw photo with no light and do
+<B>dcraw -D -4 -j -t 0</B>.
+
+<DT><B>-k darkness</B>
+
+<DD>
+When shadows appear foggy, you need to raise the darkness level.
+To measure this, apply
+<B>pamsumm -mean</B>
+
+to the dark frame generated above.
+<DT><B>-S saturation</B>
+
+<DD>
+When highlights appear pink, you need to lower the saturation level.
+To measure this, take a picture of something shiny and do
+<B>dcraw -D -4 -j -c</B>
+
+photo.raw
+<B>| pamsumm -max</B>
+
+<DT><B></B>
+
+<DD>
+The default darkness and saturation are usually correct.
+<DT><B>-n noise_threshold</B>
+
+<DD>
+Use wavelets to erase noise while preserving real detail.
+The best threshold should be somewhere between 100 and 1000.
+<DT><B>-C red_mag blue_mag</B>
+
+<DD>
+Enlarge the raw red and blue layers by the given factors,
+typically 0.999 to 1.001, to correct chromatic aberration.
+<DT><B>-H 0</B>
+
+<DD>
+Clip all highlights to solid white (default).
+<DT><B>-H 1</B>
+
+<DD>
+Leave highlights unclipped in various shades of pink.
+<DT><B>-H 2</B>
+
+<DD>
+Blend clipped and unclipped values together for a gradual fade
+to white.
+<DT><B>-H 3+</B>
+
+<DD>
+Reconstruct highlights. Low numbers favor whites; high numbers
+favor colors. Try
+<B>-H 5</B>
+
+as a compromise. If that's not good enough, do
+<B>-H 9</B>,
+
+cut out the non-white highlights, and paste them into an image
+generated with
+<B>-H 3</B>.
+
+</DL>
+<A NAME="lbAG"> </A>
+<H2>COLOR OPTIONS</H2>
+
+By default,
+<B>dcraw</B>
+
+uses a fixed white balance based on a color chart illuminated
+with a standard D65 lamp.
+<DL COMPACT>
+<DT><B>-w</B>
+
+<DD>
+Use the white balance specified by the camera.
+If this is not found, print a warning and use another method.
+<DT><B>-a</B>
+
+<DD>
+Calculate the white balance by averaging the entire image.
+<DT><B>-A left top width height</B>
+
+<DD>
+Calculate the white balance by averaging a rectangular area.
+First do
+<B>dcraw -j -t 0</B>
+
+and select an area of neutral grey color.
+<DT><B>-r mul0 mul1 mul2 mul3</B>
+
+<DD>
+Specify your own raw white balance.
+These multipliers can be cut and pasted from the output of
+<B>dcraw -v</B>.
+
+<DT><B>+M</B> or <B>-M</B>
+
+<DD>
+Use (or don't use) any color matrix from the camera metadata.
+The default is
+<B>+M</B>
+
+if
+<B>-w</B>
+
+is set,
+<B>-M</B>
+
+otherwise.
+This option only affects Olympus, Leaf, and Phase One cameras.
+<DT><B>-o [0-5]</B>
+
+<DD>
+Select the output colorspace when the
+<B>-p</B>
+
+option is not used:
+<P>
+<B> 0</B>
+
+ Raw color (unique to each camera)
+<BR>
+
+<B> 1</B>
+
+ sRGB D65 (default)
+<BR>
+
+<B> 2</B>
+
+ Adobe RGB (1998) D65

+<BR>
+
+<B> 4</B>

+<BR>
+
+<B> 5</B>
+
+ XYZ
+<DT><B>-p camera.icm</B> [ <B>-o output.icm</B> ]
+
+<DD>
+Use ICC profiles to define the camera's raw colorspace and the
+desired output colorspace (sRGB by default).
+<DT><B>-p embed</B>
+
+<DD>
+Use the ICC profile embedded in the raw photo.
+</DL>
+<A NAME="lbAH"> </A>
+<H2>INTERPOLATION OPTIONS</H2>
+
+<DL COMPACT>
+<DT><B>-d</B>
+
+<DD>
+Show the raw data as a grayscale image with no interpolation.
+Good for photographing black-and-white documents.
+<DT><B>-D</B>
+
+<DD>
+Same as
+<B>-d</B>,
+
+but with the original unscaled pixel values.
+<DT><B>-E</B>
+
+<DD>
+Same as
+<B>-D</B>,
+
+but masked pixels are not cropped.
+<DT><B>-h</B>
+
+<DD>
+Output a half-size color image. Twice as fast as
+<B>-q 0</B>.
+
+<DT><B>-q 0</B>
+
+<DD>
+Use high-speed, low-quality bilinear interpolation.
+<DT><B>-q 1</B>
+
+<DD>
+Use Variable Number of Gradients (VNG) interpolation.
+<DT><B>-q 2</B>
+
+<DD>
+Use Patterned Pixel Grouping (PPG) interpolation.
+<DT><B>-q 3</B>
+
+<DD>
+Use Adaptive Homogeneity-Directed (AHD) interpolation.
+<DT><B>-f</B>
+
+<DD>
+Interpolate RGB as four colors. Use this if the output shows
+false 2x2 meshes with VNG or mazes with AHD.
+<DT><B>-m number_of_passes</B>
+
+<DD>
+After interpolation, clean up color artifacts by repeatedly
+applying a 3x3 median filter to the R-G and B-G channels.
+</DL>
+<A NAME="lbAI"> </A>
+<H2>OUTPUT OPTIONS</H2>
+
+By default,
+<B>dcraw</B>
+
+writes PGM/PPM/PAM with 8-bit samples, a BT.709 gamma curve,
+a histogram-based white level, and no metadata.
+<DL COMPACT>
+<DT><B>-W</B>
+
+<DD>
+Use a fixed white level, ignoring the image histogram.
+<DT><B>-b brightness</B>
+
+<DD>
+Divide the white level by this number, 1.0 by default.
+<DT><B>-g power toe_slope</B>
+
+<DD>
+Set the gamma curve, by default BT.709
+(<B>-g 2.222 4.5</B>).
+
+If you prefer sRGB gamma, use
+<B>-g 2.4 12.92</B>.
+
+For a simple power curve, set the toe slope to zero.
+<DT><B>-6</B>
+
+<DD>
+Write sixteen bits per sample instead of eight.
+<DT><B>-4</B>
+
+<DD>
+Linear 16-bit, same as
+<B>-6 -W -g 1 1</B>.
+
+<DT><B>-T</B>
+
+<DD>
+Write TIFF with metadata instead of PGM/PPM/PAM.
+<DT><B>-t [0-7,90,180,270]</B>
+
+<DD>
+Flip the output image. By default,
+<B>dcraw</B>
+
+applies the flip specified by the camera.
+<B>-t 0</B>
+
+disables all flipping.
+<DT><B>-j</B>
+
+<DD>
+For Fuji Super CCD cameras, show the image tilted 45 degrees.
+For cameras with non-square pixels, do not stretch the image to
+its correct aspect ratio. In any case, this option guarantees
+that each output pixel corresponds to one raw pixel.
+<DT><B>-s [0..N-1]</B> or <B>-s all</B>
+
+<DD>
+If a file contains N raw images, choose one or "all" to decode.
+For example, Fuji Super CCD SR cameras generate a second image
+underexposed four stops to show detail in the highlights.
+</DL>
+<A NAME="lbAJ"> </A>
+<H2>FILES</H2>
+
+<DL COMPACT>
+<DT>:./.badpixels, ../.badpixels, ../../.badpixels, ...<DD>
+List of your camera's dead pixels, so that
+<B>dcraw</B>
+
+can interpolate around them. Each line specifies the column,
+row, and UNIX time of death for one pixel. For example:
+<P>
+<PRE>
+ 962 91 1028350000 # died between August 1 and 4, 2002
+1285 1067 0 # don't know when this pixel died
+</PRE>
+
+<P>
+These coordinates are before any cropping or rotation, so use
+<B>dcraw -j -t 0</B>
+
+to locate dead pixels.

- * libtiff 3.9.5 released.
-
-2011-04-09 Bob Friesenhahn <bfriesen at simple.dallas.tx.us>
-
- * configure.ac: Should use AC_CANONICAL_HOST since host specifies
- the run-time target whereas target is used to specify the final
- output target if the package is a build tool (like a compiler),
- which libtiff is not. Resolves libtiff bug 2307 "Use
- AC_CANONICAL_HOST macro".
-
-2011-04-02 Bob Friesenhahn <bfriesen at simple.dallas.tx.us>
-
- * tools/fax2ps.c (main): Use tmpfile() rather than mkstemp() since
- it is much more portable. Tmpfile is included in ISO/IEC
- 9899:1990 and the WIN32 CRT.

-
- * libtiff/tif_fax3.h: Protect against a fax VL(n) codeword commanding
- a move left. Without this, a malicious input file can generate an
- indefinitely large series of runs without a0 ever reaching the right
- margin, thus overrunning our buffer of run lengths. Per CVE-2011-0192.
- This is a modified version of a patch proposed by Drew Yao of Apple
- Product Security. It adds an unexpected() report, and disallows the
- equality case, since emitting a run without increasing a0 still allows
- buffer overrun.

-
-2010-06-30 Andrey Kiselev <dron at ak4719.spb.edu>

- in t2p_read_tiff_size() causes t2p->tiff_datasize to be set entirely
- wrong for COMPRESSION_JPEG case, resulting in memory stomp if actual
- size is larger. Also, there are a bunch of places that try to
- memset() a malloc'd buffer before checking for malloc failure, which
- would result in core dump if there actually were a failure. (#2211)
-
-2010-06-11 Bob Friesenhahn <bfriesen at simple.dallas.tx.us>
-
- * tools/tiff2rgba.c: Applied portion of patch (from Tom Lane)

-
- * libtiff 3.9.3 released.
-
- * tools/tiffcp.c (tiffcp): Applied Tom Lane's patch to reject

- buffer due to integer overflow in TIFFroundup() and several other
- potential overflows. In conjunction with the fix to TIFFhowmany(),
- fixes CVE-2010-1411.
-
- * libtiff/tiffiop.h (TIFFhowmany): Return zero if parameters would
- result in an integer overflow. This causes TIFFroundup() to also
- return zero if there would be an integer overflow.
-
- * libtiff/tif_read.c (TIFFReadBufferSetup): Return an error if
- tif_rawdatasize becomes zero due to an initial raw size of zero or

-
- * libtiff/tools/tiffcp.c: add a new option -x to force merged tiff
- file PAGENUMBER value in sequence for users who care the page
- sequence, this will also prevent tiff2pdf from creating pdf file from
- the merged tiff file with wrong page sequence.
-
-2010-05-07 Frank Warmerdam <warmerdam at pobox.com>
-
- * libtiff/tif_jpeg.c: Ensure that quality is always set in
- JPEGPreEncode(), not just when we want to output local tables.
- Otherwise the quality used during compression may not be right and
- might not match the tables in the tables tag. This bug only occurs
- when seeking between directories in the midst of writing blocks.

- from Alexey Chupahin.
-
-2007-11-22 Frank Warmerdam <warmerdam at pobox.com>
-
- * tif_write.c: Rip out the fancy logic in TIFFAppendToStrip() for
- establishing if an existing tile can be rewritten to the same location
- by comparing the current size to all the other blocks in the same
- directory. This is dangerous in many situations and can easily
- corrupt a file. (observed in esoteric GDAL situation that's hard to
- document). This change involves leaving the stripbytecount[] values
- unaltered till TIFFAppendToStrip(). Now we only write a block back
- to the same location it used to be at if the new data is the same
- size or smaller - otherwise we move it to the end of file.
-
- * tif_dirwrite.c: Try to avoid writing out a full readbuffer of tile
- data when writing the directory just because we have BEENWRITING at
- some point in the past. This was causing odd junk to be written out
- in a tile of data when a single tile had an interleaving of reading
- and writing with reading last. (highlighted by gdal
- autotest/gcore/tif_write.py test 7.
-
- * tif_predict.c: use working buffer in PredictorEncodeTile to avoid
- modifying callers buffer.

-
-2007-09-13 Frank Warmerdam <warmerdam at pobox.com>

- ignored. (Bug #1585)
-
-2007-07-18 Andrey Kiselev <dron at ak4719.spb.edu>

- by Leon Bottou.
-
-2007-06-29 Bob Friesenhahn <bfriesen at simple.dallas.tx.us>
-
- * libtiff/tif_dirinfo.c (_TIFFFindFieldInfo): Don't attempt to

- tif_fax3.c, tif_jbig.c, tif_luv.c, tif_ojpeg.c, tif_pixarlog.c,
- tif_predict.c, tif_zip.c}: Finally fix bug
-
- http://bugzilla.remotesensing.org/show_bug.cgi?id=1274
-
- by introducing _TIFFMergeFieldInfo() returning integer error status
- instead of void in case of problems with field merging (e.g., if the
- field with such a tag already registered). TIFFMergeFieldInfo() in
- public API remains void. Use _TIFFMergeFieldInfo() everywhere and
- check returned value.
-
-2007-04-07 Frank Warmerdam <warmerdam at pobox.com>
-
- * contrib/addtiffo/tif_overview.c: Fix problems with odd sized output
- blocks in TIFF_DownSample_Subsampled() (bug 1542).
-
-2007-04-06 Frank Warmerdam <warmerdam at pobox.com>
-
- * libtiff/tif_jpeg.c: Changed JPEGInitializeLibJPEG() so that it
- will convert from decompressor to compressor or compress to decompress
- if required by the force arguments. This works around a problem in
- where the JPEGFixupTestSubsampling() may cause a decompressor to
- be setup on a directory when later a compressor is required with the
- force flag set. Occurs with the addtiffo program for instance.

-
- * libtiff/tif_getimage.c: If DEFAULT_EXTRASAMPLE_AS_ALPHA is 1
- (defined in tiffconf.h - 1 by default) then the RGBA interface
- will assume that a fourth extra sample is ASSOCALPHA if the
- EXTRASAMPLE value isn't set for it. This changes the behaviour of
- the library, but makes it work better with RGBA files produced by
- lots of applications that don't mark the alpha values properly.

-
- * configure, Makefile.in, etc: added support for OPTIMIZER being
- set from config.site.

-2001-03-28 Frank Warmerdam <warmerdam at pobox.com>
-
- * fax2ps.c: Helge (libtiff at oldach.net) submitted fix:
-
- Here's a fix for fax2ps that corrects behaviour for non-Letter paper
- sizes. It fixes two problems:
-
- Without scaling (-S) the fax is now centered on the page size specified
- with -H and/or -W. Before, fax2ps was using an obscure and practially
- useless algorithm to allocate the image relative to Letter sized paper
- which sometime sled to useless whitespace on the paper, while at the
- same time cutting of the faxes printable area at the opposite border.
-
- Second, scaling now preserves aspect ratio, which makes unusual faxes
- (in particular short ones) print properly.
-
- See http://bugzilla.remotesensing.org/show_bug.cgi?id=35
-
- * tiff2ps.c/tiff2ps.1: Substantial changes to tiff2ps by
- Bruce A. Mallett. See check message for detailed information
- on all the changes, including a faster encoder, fixes for level
- 2 PostScript, and support for the imagemask operator.
-
-2001-03-27 Frank Warmerdam <warmerdam at pobox.com>

-
-2001-03-16 Frank Warmerdam <warmerdam at pobox.com>

-
- * libtiff/tif_dirinfo.c: don't declare tiffFieldInfo static on VMS.
- Some sort of weird VMS thing.
-
- http://bugzilla.remotesensing.org/show_bug.cgi?id=31
-
- * tif_luv.c/tiff.h/tiffio.h:
- New version of TIFF LogLuv (SGILOG) modules contributed by Greg Ward
- (greg at shutterfly.com). He writes:
-
- 1) I improved the gamut-mapping function in tif_luv.c for imaginary
- colors, because some images were being super-saturated on the input
- side and this resulted in some strange color shifts in the output.
-
- 2) I added a psuedotag in tiff.h to control random dithering during
- LogLuv encoding. This is turned off by default for 32-bit LogLuv and
- on for 24-bit LogLuv output. Dithering improves the average color
- accuracy over the image.
-
- 3) I added a #define for LOG_LUV_PUBLIC, which is enabled by default in
- tiffio.h, to expose internal routines for converting between LogLuv and
- XYZ coordinates. This is helpful for writing more efficient,
- specialized conversion routines, especially for reading LogLuv files.
-
- Changes applied with minor edits.
-
-2001-01-23 Frank Warmerdam <warmerdam at pobox.com>
-
- * tif_fax3.c: keep rw_mode flag internal to fax3 state to remember
- whether we are encoding or decoding. This is to ensure graceful
- recovery if TIFFClientOpen() discovers an attempt to open a compressed
- file for "r+" access, and subsequently close it, as it resets the
- tif_mode flag to O_RDONLY in this case to avoid writes, confusing the
- compressor's concept of whether it is in encode or decode mode.
-
-2001-01-08 Mike Welles <mike at bangstate.com>

- installed with the others. They are not installed by default.
-
- * libtiff/Makefile.in: Added @MACHLIBDEPS@ to LINUXdso and GNULDdso
- targets so libtiff.so will be built with an explicit dependency
- on libm.so.
-
- * libtiff/Makefile.in: Use softlinks to link libtiff.so.3 to
- libtiff.so.3.5.5.
-
- * libtiff/Makefile.in & configure: Remove all references to the ALPHA
- file, or ALPHA version logic. Added stuff about DIST_POINT in
- place of DIST_TYPE and the alpha release number stuff.
-
-2000-11-22 Frank Warmerdam <warmerdam at pobox.com>
-
- * I have applied a patch from Steffen Moeller <moeller at ebi.ac.uk> to
- the configure script so that it now accepts the --prefix, and
- --exec-prefix directives.
-
-2000-11-13 Frank Warmerdam <warmerda at cs46980-c>
-
- * I have made a variety of modifications in an effort to ensure the
- TIFFLIB_VERSION macro is automatically generated from the RELEASE-DATE
- file which seems to be updated regularly.
-
- o mkversion.c now reads RELEASE-DATE and emits TIFFLIB_VERSION in
- version include file.
- o renamed version.h to tiffvers.h because we now have to install it
- with the public libtiff include files.
- o include tiffvers.h in tiffio.h.

-
-2000-10-19 Frank Warmerdam <warmerda at cs46980-c>
-
- * tools/rgb2ycbcr.c: fixed output strip size to account for vertical

-
-2000-09-30 Frank Warmerdam <warmerda at cs46980-c>
-
- * Modified TIFFClientOpen() to emit an error on an attempt to
- open a comperessed file for update (O_RDWR/r+) access. This is
- because the compressor/decompressor code gets very confused when
- the mode is O_RDWR, assuming this means writing only. See
- bug http://bugzilla.remotesensing.org/show_bug.cgi?id=13
-
-2000-09-27 Frank Warmerdam <warmerda at cs46980-c>

-Low-level file handling
-~~~~~~~~~~~~~~~~~~~~~~~
-The functions in osfcn.h are unavailable when compiling under C, as it's a
-C++ header. Therefore they have been implemented here.
-
-Now, why have I done it this way?
-
-The definitive API library for RISC OS is Jonathan Coxhead's OSLib, which
-uses heavily optimised ARM assembler or even plain inline SWI calls for
-maximum performance and minimum runtime size. However, I don't want to make
-LIBTIFF need that to survive. Therefore I have also emulated the functions
-using macros to _swi() and _swix() defined in the swis.h header, and
-borrowing types from kernel.h, which is less efficient but doesn't need any
-third-party libraries.

-/*
- * TIFF Library.
- * LogLuv compression support for high dynamic range images.
- *
- * Contributed by Greg Larson.
- *
- * LogLuv image support uses the TIFF library to store 16 or 10-bit
- * log luminance values with 8 bits each of u and v or a 14-bit index.
- *
- * The codec can take as input and produce as output 32-bit IEEE float values
- * as well as 16-bit integer values. A 16-bit luminance is interpreted
- * as a sign bit followed by a 15-bit integer that is converted
- * to and from a linear magnitude using the transformation:
- *
- * L = 2^( (Le+.5)/256 - 64 ) # real from 15-bit
- *
- * Le = floor( 256*(log2(L) + 64) ) # 15-bit from real
- *
- * The actual conversion to world luminance units in candelas per sq. meter
- * requires an additional multiplier, which is stored in the TIFFTAG_STONITS.
- * This value is usually set such that a reasonable exposure comes from
- * clamping decoded luminances above 1 to 1 in the displayed image.
- *
- * The 16-bit values for u and v may be converted to real values by dividing
- * each by 32768. (This allows for negative values, which aren't useful as
- * far as we know, but are left in case of future improvements in human
- * color vision.)
- *
- * Conversion from (u,v), which is actually the CIE (u',v') system for
- * you color scientists, is accomplished by the following transformation:
- *
- * u = 4*x / (-2*x + 12*y + 3)
- * v = 9*y / (-2*x + 12*y + 3)
- *
- * x = 9*u / (6*u - 16*v + 12)
- * y = 4*v / (6*u - 16*v + 12)
- *
- * This process is greatly simplified by passing 32-bit IEEE floats
- * for each of three CIE XYZ coordinates. The codec then takes care
- * of conversion to and from LogLuv, though the application is still
- * responsible for interpreting the TIFFTAG_STONITS calibration factor.
- *
- * By definition, a CIE XYZ vector of [1 1 1] corresponds to a neutral white
- * point of (x,y)=(1/3,1/3). However, most color systems assume some other
- * white point, such as D65, and an absolute color conversion to XYZ then
- * to another color space with a different white point may introduce an
- * unwanted color cast to the image. It is often desirable, therefore, to
- * perform a white point conversion that maps the input white to [1 1 1]
- * in XYZ, then record the original white point using the TIFFTAG_WHITEPOINT
- * tag value. A decoder that demands absolute color calibration may use
- * this white point tag to get back the original colors, but usually it
- * will be ignored and the new white point will be used instead that
- * matches the output color space.
- *
- * Pixel information is compressed into one of two basic encodings, depending
- * on the setting of the compression tag, which is one of COMPRESSION_SGILOG
- * or COMPRESSION_SGILOG24. For COMPRESSION_SGILOG, greyscale data is
- * stored as:
- *
- * 1 15
- * |-+---------------|
- *
- * COMPRESSION_SGILOG color data is stored as:
- *
- * 1 15 8 8
- * |-+---------------|--------+--------|
- * S Le ue ve
- *
- * For the 24-bit COMPRESSION_SGILOG24 color format, the data is stored as:
- *
- * 10 14
- * |----------|--------------|
- * Le' Ce
- *
- * There is no sign bit in the 24-bit case, and the (u,v) chromaticity is
- * encoded as an index for optimal color resolution. The 10 log bits are
- * defined by the following conversions:
- *
- * L = 2^((Le'+.5)/64 - 12) # real from 10-bit
- *
- * Le' = floor( 64*(log2(L) + 12) ) # 10-bit from real
- *
- * The 10 bits of the smaller format may be converted into the 15 bits of
- * the larger format by multiplying by 4 and adding 13314. Obviously,
- * a smaller range of magnitudes is covered (about 5 orders of magnitude
- * instead of 38), and the lack of a sign bit means that negative luminances
- * are not allowed. (Well, they aren't allowed in the real world, either,
- * but they are useful for certain types of image processing.)
- *
- * The desired user format is controlled by the setting the internal
- * pseudo tag TIFFTAG_SGILOGDATAFMT to one of:
- * SGILOGDATAFMT_FLOAT = IEEE 32-bit float XYZ values
- * SGILOGDATAFMT_16BIT = 16-bit integer encodings of logL, u and v
- * Raw data i/o is also possible using:
- * SGILOGDATAFMT_RAW = 32-bit unsigned integer with encoded pixel
- * In addition, the following decoding is provided for ease of display:
- * SGILOGDATAFMT_8BIT = 8-bit default RGB gamma-corrected values
- *
- * For grayscale images, we provide the following data formats:
- * SGILOGDATAFMT_FLOAT = IEEE 32-bit float Y values
- * SGILOGDATAFMT_16BIT = 16-bit integer w/ encoded luminance
- * SGILOGDATAFMT_8BIT = 8-bit gray monitor values
- *
- * Note that the COMPRESSION_SGILOG applies a simple run-length encoding
- * scheme by separating the logL, u and v bytes for each row and applying
- * a PackBits type of compression. Since the 24-bit encoding is not
- * adaptive, the 32-bit color format takes less space in many cases.
- *
- * Further control is provided over the conversion from higher-resolution
- * formats to final encoded values through the pseudo tag
- * TIFFTAG_SGILOGENCODE:
- * SGILOGENCODE_NODITHER = do not dither encoded values
- * SGILOGENCODE_RANDITHER = apply random dithering during encoding
- *
- * The default value of this tag is SGILOGENCODE_NODITHER for
- * COMPRESSION_SGILOG to maximize run-length encoding and
- * SGILOGENCODE_RANDITHER for COMPRESSION_SGILOG24 to turn
- * quantization errors into noise.

-/* WARNING: The type of JPEG encapsulation defined by the TIFF Version 6.0
- specification is now totally obsolete and deprecated for new applications and

- still present on some users' computer systems. It will never be extended
- to write such files. Writing new-style JPEG compressed TIFFs is implemented
- in tif_jpeg.c.
-
- The code is carefully crafted to robustly read all gathered JPEG-in-TIFF
- testfiles, and anticipate as much as possible all other... But still, it may
- fail on some. If you encounter problems, please report them on the TIFF
- mailing list and/or to Joris Van Damme <info at awaresystems.be>.
-
- Please read the file called "TIFF Technical Note #2" if you need to be

- is linked to from the LibTiff site <http://www.remotesensing.org/libtiff/>
- and from AWare Systems' TIFF section
- <http://www.awaresystems.be/imaging/tiff.html>. It is also absorbed
- in Adobe's specification supplements, marked "draft" up to this day, but
- supported by the TIFF community.

-/* What is what, and what is not?
-
- This decoder starts with an input stream, that is essentially the JpegInterchangeFormat
- stream, if any, followed by the strile data, if any. This stream is read in
- OJPEGReadByte and related functions.
-
- It analyzes the start of this stream, until it encounters non-marker data, i.e.
- compressed image data. Some of the header markers it sees have no actual content,
- like the SOI marker, and APP/COM markers that really shouldn't even be there. Some
- other markers do have content, and the valuable bits and pieces of information
- in these markers are saved, checking all to verify that the stream is more or
- less within expected bounds. This happens inside the OJPEGReadHeaderInfoSecStreamXxx
- functions.
-
- Some OJPEG imagery contains no valid JPEG header markers. This situation is picked
- up on if we've seen no SOF marker when we're at the start of the compressed image
- data. In this case, the tables are read from JpegXxxTables tags, and the other
- bits and pieces of information is initialized to its most basic value. This is
- implemented in the OJPEGReadHeaderInfoSecTablesXxx functions.
-
- When this is complete, a good and valid JPEG header can be assembled, and this is
- passed through to LibJpeg. When that's done, the remainder of the input stream, i.e.
- the compressed image data, can be passed through unchanged. This is done in
- OJPEGWriteStream functions.
-
- LibTiff rightly expects to know the subsampling values before decompression. Just like
- in new-style JPEG-in-TIFF, though, or even more so, actually, the YCbCrsubsampling
- tag is notoriously unreliable. To correct these tag values with the ones inside
- the JPEG stream, the first part of the input stream is pre-scanned in
- OJPEGSubsamplingCorrect, making no note of any other data, reporting no warnings
- or errors, up to the point where either these values are read, or it's clear they
- aren't there. This means that some of the data is read twice, but we feel speed
- in correcting these values is important enough to warrant this sacrifice. Allthough
- there is currently no define or other configuration mechanism to disable this behaviour,
- the actual header scanning is build to robustly respond with error report if it
- should encounter an uncorrected mismatch of subsampling values. See
- OJPEGReadHeaderInfoSecStreamSof.
-
- The restart interval and restart markers are the most tricky part... The restart
- interval can be specified in a tag. It can also be set inside the input JPEG stream.
- It can be used inside the input JPEG stream. If reading from strile data, we've
- consistenly discovered the need to insert restart markers in between the different
- striles, as is also probably the most likely interpretation of the original TIFF 6.0
- specification. With all this setting of interval, and actual use of markers that is not
- predictable at the time of valid JPEG header assembly, the restart thing may turn
- out the Achilles heel of this implementation. Fortunately, most OJPEG writer vendors
- succeed in reading back what they write, which may be the reason why we've been able
- to discover ways that seem to work.
-
- Some special provision is made for planarconfig separate OJPEG files. These seem
- to consistently contain header info, a SOS marker, a plane, SOS marker, plane, SOS,
- and plane. This may or may not be a valid JPEG configuration, we don't know and don't
- care. We want LibTiff to be able to access the planes individually, without huge
- buffering inside LibJpeg, anyway. So we compose headers to feed to LibJpeg, in this
- case, that allow us to pass a single plane such that LibJpeg sees a valid
- single-channel JPEG stream. Locating subsequent SOS markers, and thus subsequent
- planes, is done inside OJPEGReadSecondarySos.
-
- The benefit of the scheme is... that it works, basically. We know of no other that
- does. It works without checking software tag, or otherwise going about things in an
- OJPEG flavor specific manner. Instead, it is a single scheme, that covers the cases
- with and without JpegInterchangeFormat, with and without striles, with part of
- the header in JpegInterchangeFormat and remainder in first strile, etc. It is forgiving
- and robust, may likely work with OJPEG flavors we've not seen yet, and makes most out
- of the data.
-
- Another nice side-effect is that a complete JPEG single valid stream is build if
- planarconfig is not separate (vast majority). We may one day use that to build
- converters to JPEG, and/or to new-style JPEG compression inside TIFF.
-
- A dissadvantage is the lack of random access to the individual striles. This is the
- reason for much of the complicated restart-and-position stuff inside OJPEGPreDecode.
- Applications would do well accessing all striles in order, as this will result in
- a single sequential scan of the input stream, and no restarting of LibJpeg decoding
- session.

-/* Configuration defines here are:
- * JPEG_ENCAP_EXTERNAL: The normal way to call libjpeg, uses longjump. In some environments,
- * like eg LibTiffDelphi, this is not possible. For this reason, the actual calls to
- * libjpeg, with longjump stuff, are encapsulated in dedicated functions. When
- * JPEG_ENCAP_EXTERNAL is defined, these encapsulating functions are declared external
- * to this unit, and can be defined elsewhere to use stuff other then longjump.
- * The default mode, without JPEG_ENCAP_EXTERNAL, implements the call encapsulators
- * here, internally, with normal longjump.
- * SETJMP, LONGJMP, JMP_BUF: On some machines/environments a longjump equivalent is
- * conviniently available, but still it may be worthwhile to use _setjmp or sigsetjmp
- * in place of plain setjmp. These macros will make it easier. It is useless
- * to fiddle with these if you define JPEG_ENCAP_EXTERNAL.
- * OJPEG_BUFFER: Define the size of the desired buffer here. Should be small enough so as to guarantee
- * instant processing, optimal streaming and optimal use of processor cache, but also big
- * enough so as to not result in significant call overhead. It should be at least a few
- * bytes to accomodate some structures (this is verified in asserts), but it would not be
- * sensible to make it this small anyway, and it should be at most 64K since it is indexed
- * with uint16. We recommend 2K.
- * EGYPTIANWALK: You could also define EGYPTIANWALK here, but it is not used anywhere and has
- * absolutely no effect. That is why most people insist the EGYPTIANWALK is a bit silly.

- * Process library-specific flags in the open mode string.
- * The following flags may be used to control intrinsic library
- * behaviour that may or may not be desirable (usually for
- * compatibility with some application that claims to support
- * TIFF but only supports some braindead idea of what the
- * vendor thinks TIFF is):
- *
- * 'l' use little-endian byte order for creating a file
- * 'b' use big-endian byte order for creating a file
- * 'L' read/write information using LSB2MSB bit order
- * 'B' read/write information using MSB2LSB bit order
- * 'H' read/write information using host bit order
- * 'M' enable use of memory-mapped files when supported
- * 'm' disable use of memory-mapped files
- * 'C' enable strip chopping support when reading
- * 'c' disable strip chopping support
- * 'h' read TIFF header only, do not load the first IFD
- *
- * The use of the 'l' and 'b' flags is strongly discouraged.
- * These flags are provided solely because numerous vendors,
- * typically on the PC, do not correctly support TIFF; they
- * only support the Intel little-endian byte order. This
- * support is not configured by default because it supports
- * the violation of the TIFF spec that says that readers *MUST*
- * support both byte orders. It is strongly recommended that
- * you not use this feature except to deal with busted apps
- * that write invalid TIFF. And even in those cases you should
- * bang on the vendors to fix their software.
- *
- * The 'L', 'B', and 'H' flags are intended for applications
- * that can optimize operations on data by using a particular
- * bit order. By default the library returns data in MSB2LSB
- * bit order for compatibiltiy with older versions of this
- * library. Returning data in the bit order of the native cpu
- * makes the most sense but also requires applications to check
- * the value of the FillOrder tag; something they probably do
- * not do right now.
- *
- * The 'M' and 'm' flags are provided because some virtual memory
- * systems exhibit poor behaviour when large images are mapped.
- * These options permit clients to control the use of memory-mapped
- * files on a per-file basis.
- *
- * The 'C' and 'c' flags are provided because the library support
- * for chopping up large strips into multiple smaller strips is not
- * application-transparent and as such can cause problems. The 'c'
- * option permits applications that only want to look at the tags,
- * for example, to get the unadulterated TIFF tag information.

- * TIFF Library.
- * PixarLog Compression Support
- *
- * Contributed by Dan McCoy.
- *
- * PixarLog film support uses the TIFF library to store companded
- * 11 bit values into a tiff file, which are compressed using the
- * zip compressor.
- *
- * The codec can take as input and produce as output 32-bit IEEE float values
- * as well as 16-bit or 8-bit unsigned integer values.
- *
- * On writing any of the above are converted into the internal
- * 11-bit log format. In the case of 8 and 16 bit values, the
- * input is assumed to be unsigned linear color values that represent
- * the range 0-1. In the case of IEEE values, the 0-1 range is assumed to
- * be the normal linear color range, in addition over 1 values are
- * accepted up to a value of about 25.0 to encode "hot" hightlights and such.
- * The encoding is lossless for 8-bit values, slightly lossy for the
- * other bit depths. The actual color precision should be better
- * than the human eye can perceive with extra room to allow for
- * error introduced by further image computation. As with any quantized
- * color format, it is possible to perform image calculations which
- * expose the quantization error. This format should certainly be less
- * susceptable to such errors than standard 8-bit encodings, but more
- * susceptable than straight 16-bit or 32-bit encodings.
- *
- * On reading the internal format is converted to the desired output format.
- * The program can request which format it desires by setting the internal
- * pseudo tag TIFFTAG_PIXARLOGDATAFMT to one of these possible values:
- * PIXARLOGDATAFMT_FLOAT = provide IEEE float values.
- * PIXARLOGDATAFMT_16BIT = provide unsigned 16-bit integer values
- * PIXARLOGDATAFMT_8BIT = provide unsigned 8-bit integer values
- *
- * alternately PIXARLOGDATAFMT_8BITABGR provides unsigned 8-bit integer
- * values with the difference that if there are exactly three or four channels
- * (rgb or rgba) it swaps the channel order (bgr or abgr).
- *
- * PIXARLOGDATAFMT_11BITLOG provides the internal encoding directly
- * packed in 16-bit values. However no tools are supplied for interpreting
- * these values.
- *
- * "hot" (over 1.0) areas written in floating point get clamped to
- * 1.0 in the integer data types.
- *
- * When the file is closed after writing, the bit depth and sample format
- * are set always to appear as if 8-bit data has been written into it.
- * That way a naive program unaware of the particulars of the encoding
- * gets the format it is most likely able to handle.
- *
- * The codec does it's own horizontal differencing step on the coded
- * values so the libraries predictor stuff should be turned off.
- * The codec also handle byte swapping the encoded values as necessary
- * since the library does not have the information necessary
- * to know the bit depth of the raw unencoded buffer.

+ * tools/tiffcp.c: fix crash when converting YCbCr JPEG-compressed to none.
+ Based on patch by Tomasz Buchert (http://bugzilla.maptools.org/show_bug.cgi?id=2480)
+ Description: fix for Debian bug #741451
+ tiffcp crashes when converting JPEG-encoded TIFF to a different
+ encoding (like none or lzw). For example this will probably fail:
+ tiffcp -c none jpeg_encoded_file.tif output.tif
+ The reason is that when the input file contains JPEG data,
+ the tiffcp code forces conversion to RGB space. However,
+ the output normally inherits YCbCr subsampling parameters
+ from the input, which leads to a smaller working buffer
+ than necessary. The buffer is subsequently overrun inside
+ cpStripToTile() (called from writeBufferToContigTiles).
+ Note that the resulting TIFF file would be scrambled even
+ if tiffcp wouldn't crash, since the output file would contain
+ RGB data intepreted as subsampled YCbCr values.
+ This patch fixes the problem by forcing RGB space on the output
+ TIF if the input is JPEG-encoded and output is *not* JPEG-encoded.

+2014-12-21 Even Rouault <even.rouault at spatialys.com>
+
+ Fix various crasher bugs on fuzzed images.
+ * libtiff/tif_dir.c: TIFFSetField(): refuse to set negative values for
+ TIFFTAG_XRESOLUTION and TIFFTAG_YRESOLUTION that cause asserts when writing
+ the directory
+ * libtiff/tif_dirread.c: TIFFReadDirectory(): refuse to read ColorMap or
+ TransferFunction if BitsPerSample has not yet been read, otherwise reading
+ it later will cause user code to crash if BitsPerSample > 1
+ * libtiff/tif_getimage.c: TIFFRGBAImageOK(): return FALSE if LOGLUV with
+ SamplesPerPixel != 3, or if CIELAB with SamplesPerPixel != 3 or BitsPerSample != 8
+ * libtiff/tif_next.c: in the "run mode", use tilewidth for tiled images
+ instead of imagewidth to avoid crash
+ * tools/bmp2tiff.c: fix crash due to int overflow related to input BMP dimensions
+ * tools/tiff2pdf.c: fix crash due to invalid tile count (should likely be checked by
+ libtiff too). Detect invalid settings of BitsPerSample/SamplesPerPixel for CIELAB / ITULAB
+ * tools/tiffcrop.c: fix crash due to invalid TileWidth/TileHeight
+ * tools/tiffdump.c: fix crash due to overflow of entry count.
+
+2014-12-15 Even Rouault <even.rouault at spatialys.com>
+
+ * libtiff/tif_jpeg.c: Fix regression introduced on 2010-05-07 that caused
+ all tiles/strips to include quantization tables even when the jpegtablesmode
+ had the JPEGTABLESMODE_QUANT bit set.
+ Also add explicit removal of Huffman tables when jpegtablesmode has the
+ JPEGTABLESMODE_HUFF bit set, which avoids Huffman tables to be emitted in the
+ first tile/strip (only useful in update scenarios. create-only was
+ fine)
+
+2014-12-09 Bob Friesenhahn <bfriesen at simple.dallas.tx.us>
+
+ * tools/tiff2pdf.c: Assure that memory size calculations for

+
+2014-12-07 Bob Friesenhahn <bfriesen at simple.dallas.tx.us>
+
+ * tools/tiff2pdf.c (t2p_read_tiff_init): TIFFTAG_TRANSFERFUNCTION
+ tag can return one channel, with the other two channels set to
+ NULL. The tiff2pdf code was expecting that other two channels
+ were duplicate pointers in the case where there is only one

-/*
- * TIFF Library.
- * LogLuv compression support for high dynamic range images.
- *
- * Contributed by Greg Larson.
- *
- * LogLuv image support uses the TIFF library to store 16 or 10-bit
- * log luminance values with 8 bits each of u and v or a 14-bit index.
- *
- * The codec can take as input and produce as output 32-bit IEEE float values
- * as well as 16-bit integer values. A 16-bit luminance is interpreted
- * as a sign bit followed by a 15-bit integer that is converted
- * to and from a linear magnitude using the transformation:
- *
- * L = 2^( (Le+.5)/256 - 64 ) # real from 15-bit
- *
- * Le = floor( 256*(log2(L) + 64) ) # 15-bit from real
- *
- * The actual conversion to world luminance units in candelas per sq. meter
- * requires an additional multiplier, which is stored in the TIFFTAG_STONITS.
- * This value is usually set such that a reasonable exposure comes from
- * clamping decoded luminances above 1 to 1 in the displayed image.
- *
- * The 16-bit values for u and v may be converted to real values by dividing
- * each by 32768. (This allows for negative values, which aren't useful as
- * far as we know, but are left in case of future improvements in human
- * color vision.)
- *
- * Conversion from (u,v), which is actually the CIE (u',v') system for
- * you color scientists, is accomplished by the following transformation:
- *
- * u = 4*x / (-2*x + 12*y + 3)
- * v = 9*y / (-2*x + 12*y + 3)
- *
- * x = 9*u / (6*u - 16*v + 12)
- * y = 4*v / (6*u - 16*v + 12)
- *
- * This process is greatly simplified by passing 32-bit IEEE floats
- * for each of three CIE XYZ coordinates. The codec then takes care
- * of conversion to and from LogLuv, though the application is still
- * responsible for interpreting the TIFFTAG_STONITS calibration factor.
- *
- * By definition, a CIE XYZ vector of [1 1 1] corresponds to a neutral white
- * point of (x,y)=(1/3,1/3). However, most color systems assume some other
- * white point, such as D65, and an absolute color conversion to XYZ then
- * to another color space with a different white point may introduce an
- * unwanted color cast to the image. It is often desirable, therefore, to
- * perform a white point conversion that maps the input white to [1 1 1]
- * in XYZ, then record the original white point using the TIFFTAG_WHITEPOINT
- * tag value. A decoder that demands absolute color calibration may use
- * this white point tag to get back the original colors, but usually it
- * will be ignored and the new white point will be used instead that
- * matches the output color space.
- *
- * Pixel information is compressed into one of two basic encodings, depending
- * on the setting of the compression tag, which is one of COMPRESSION_SGILOG
- * or COMPRESSION_SGILOG24. For COMPRESSION_SGILOG, greyscale data is
- * stored as:
- *
- * 1 15
- * |-+---------------|
- *
- * COMPRESSION_SGILOG color data is stored as:
- *
- * 1 15 8 8
- * |-+---------------|--------+--------|
- * S Le ue ve
- *
- * For the 24-bit COMPRESSION_SGILOG24 color format, the data is stored as:
- *
- * 10 14
- * |----------|--------------|
- * Le' Ce
- *
- * There is no sign bit in the 24-bit case, and the (u,v) chromaticity is
- * encoded as an index for optimal color resolution. The 10 log bits are
- * defined by the following conversions:
- *
- * L = 2^((Le'+.5)/64 - 12) # real from 10-bit
- *
- * Le' = floor( 64*(log2(L) + 12) ) # 10-bit from real
- *
- * The 10 bits of the smaller format may be converted into the 15 bits of
- * the larger format by multiplying by 4 and adding 13314. Obviously,
- * a smaller range of magnitudes is covered (about 5 orders of magnitude
- * instead of 38), and the lack of a sign bit means that negative luminances
- * are not allowed. (Well, they aren't allowed in the real world, either,
- * but they are useful for certain types of image processing.)
- *
- * The desired user format is controlled by the setting the internal
- * pseudo tag TIFFTAG_SGILOGDATAFMT to one of:
- * SGILOGDATAFMT_FLOAT = IEEE 32-bit float XYZ values
- * SGILOGDATAFMT_16BIT = 16-bit integer encodings of logL, u and v
- * Raw data i/o is also possible using:
- * SGILOGDATAFMT_RAW = 32-bit unsigned integer with encoded pixel
- * In addition, the following decoding is provided for ease of display:
- * SGILOGDATAFMT_8BIT = 8-bit default RGB gamma-corrected values
- *
- * For grayscale images, we provide the following data formats:
- * SGILOGDATAFMT_FLOAT = IEEE 32-bit float Y values
- * SGILOGDATAFMT_16BIT = 16-bit integer w/ encoded luminance
- * SGILOGDATAFMT_8BIT = 8-bit gray monitor values
- *
- * Note that the COMPRESSION_SGILOG applies a simple run-length encoding
- * scheme by separating the logL, u and v bytes for each row and applying
- * a PackBits type of compression. Since the 24-bit encoding is not
- * adaptive, the 32-bit color format takes less space in many cases.
- *
- * Further control is provided over the conversion from higher-resolution
- * formats to final encoded values through the pseudo tag
- * TIFFTAG_SGILOGENCODE:
- * SGILOGENCODE_NODITHER = do not dither encoded values
- * SGILOGENCODE_RANDITHER = apply random dithering during encoding
- *
- * The default value of this tag is SGILOGENCODE_NODITHER for
- * COMPRESSION_SGILOG to maximize run-length encoding and
- * SGILOGENCODE_RANDITHER for COMPRESSION_SGILOG24 to turn
- * quantization errors into noise.

+ * TIFF Library.
+ * LogLuv compression support for high dynamic range images.
+ *
+ * Contributed by Greg Larson.
+ *
+ * LogLuv image support uses the TIFF library to store 16 or 10-bit
+ * log luminance values with 8 bits each of u and v or a 14-bit index.
+ *
+ * The codec can take as input and produce as output 32-bit IEEE float values
+ * as well as 16-bit integer values. A 16-bit luminance is interpreted
+ * as a sign bit followed by a 15-bit integer that is converted
+ * to and from a linear magnitude using the transformation:
+ *
+ * L = 2^( (Le+.5)/256 - 64 ) # real from 15-bit
+ *
+ * Le = floor( 256*(log2(L) + 64) ) # 15-bit from real
+ *
+ * The actual conversion to world luminance units in candelas per sq. meter
+ * requires an additional multiplier, which is stored in the TIFFTAG_STONITS.
+ * This value is usually set such that a reasonable exposure comes from
+ * clamping decoded luminances above 1 to 1 in the displayed image.
+ *
+ * The 16-bit values for u and v may be converted to real values by dividing
+ * each by 32768. (This allows for negative values, which aren't useful as
+ * far as we know, but are left in case of future improvements in human
+ * color vision.)
+ *
+ * Conversion from (u,v), which is actually the CIE (u',v') system for
+ * you color scientists, is accomplished by the following transformation:
+ *
+ * u = 4*x / (-2*x + 12*y + 3)
+ * v = 9*y / (-2*x + 12*y + 3)
+ *
+ * x = 9*u / (6*u - 16*v + 12)
+ * y = 4*v / (6*u - 16*v + 12)
+ *
+ * This process is greatly simplified by passing 32-bit IEEE floats
+ * for each of three CIE XYZ coordinates. The codec then takes care
+ * of conversion to and from LogLuv, though the application is still
+ * responsible for interpreting the TIFFTAG_STONITS calibration factor.
+ *
+ * By definition, a CIE XYZ vector of [1 1 1] corresponds to a neutral white
+ * point of (x,y)=(1/3,1/3). However, most color systems assume some other
+ * white point, such as D65, and an absolute color conversion to XYZ then
+ * to another color space with a different white point may introduce an
+ * unwanted color cast to the image. It is often desirable, therefore, to
+ * perform a white point conversion that maps the input white to [1 1 1]
+ * in XYZ, then record the original white point using the TIFFTAG_WHITEPOINT
+ * tag value. A decoder that demands absolute color calibration may use
+ * this white point tag to get back the original colors, but usually it
+ * will be ignored and the new white point will be used instead that
+ * matches the output color space.
+ *
+ * Pixel information is compressed into one of two basic encodings, depending
+ * on the setting of the compression tag, which is one of COMPRESSION_SGILOG
+ * or COMPRESSION_SGILOG24. For COMPRESSION_SGILOG, greyscale data is
+ * stored as:
+ *
+ * 1 15
+ * |-+---------------|
+ *
+ * COMPRESSION_SGILOG color data is stored as:
+ *
+ * 1 15 8 8
+ * |-+---------------|--------+--------|
+ * S Le ue ve
+ *
+ * For the 24-bit COMPRESSION_SGILOG24 color format, the data is stored as:
+ *
+ * 10 14
+ * |----------|--------------|
+ * Le' Ce
+ *
+ * There is no sign bit in the 24-bit case, and the (u,v) chromaticity is
+ * encoded as an index for optimal color resolution. The 10 log bits are
+ * defined by the following conversions:
+ *
+ * L = 2^((Le'+.5)/64 - 12) # real from 10-bit
+ *
+ * Le' = floor( 64*(log2(L) + 12) ) # 10-bit from real
+ *
+ * The 10 bits of the smaller format may be converted into the 15 bits of
+ * the larger format by multiplying by 4 and adding 13314. Obviously,
+ * a smaller range of magnitudes is covered (about 5 orders of magnitude
+ * instead of 38), and the lack of a sign bit means that negative luminances
+ * are not allowed. (Well, they aren't allowed in the real world, either,
+ * but they are useful for certain types of image processing.)
+ *
+ * The desired user format is controlled by the setting the internal
+ * pseudo tag TIFFTAG_SGILOGDATAFMT to one of:
+ * SGILOGDATAFMT_FLOAT = IEEE 32-bit float XYZ values
+ * SGILOGDATAFMT_16BIT = 16-bit integer encodings of logL, u and v
+ * Raw data i/o is also possible using:
+ * SGILOGDATAFMT_RAW = 32-bit unsigned integer with encoded pixel
+ * In addition, the following decoding is provided for ease of display:
+ * SGILOGDATAFMT_8BIT = 8-bit default RGB gamma-corrected values
+ *
+ * For grayscale images, we provide the following data formats:
+ * SGILOGDATAFMT_FLOAT = IEEE 32-bit float Y values
+ * SGILOGDATAFMT_16BIT = 16-bit integer w/ encoded luminance
+ * SGILOGDATAFMT_8BIT = 8-bit gray monitor values
+ *
+ * Note that the COMPRESSION_SGILOG applies a simple run-length encoding
+ * scheme by separating the logL, u and v bytes for each row and applying
+ * a PackBits type of compression. Since the 24-bit encoding is not
+ * adaptive, the 32-bit color format takes less space in many cases.
+ *
+ * Further control is provided over the conversion from higher-resolution
+ * formats to final encoded values through the pseudo tag
+ * TIFFTAG_SGILOGENCODE:
+ * SGILOGENCODE_NODITHER = do not dither encoded values
+ * SGILOGENCODE_RANDITHER = apply random dithering during encoding
+ *
+ * The default value of this tag is SGILOGENCODE_NODITHER for
+ * COMPRESSION_SGILOG to maximize run-length encoding and
+ * SGILOGENCODE_RANDITHER for COMPRESSION_SGILOG24 to turn
+ * quantization errors into noise.

-/* What is what, and what is not?
-
- This decoder starts with an input stream, that is essentially the JpegInterchangeFormat
- stream, if any, followed by the strile data, if any. This stream is read in
- OJPEGReadByte and related functions.
-
- It analyzes the start of this stream, until it encounters non-marker data, i.e.
- compressed image data. Some of the header markers it sees have no actual content,
- like the SOI marker, and APP/COM markers that really shouldn't even be there. Some
- other markers do have content, and the valuable bits and pieces of information
- in these markers are saved, checking all to verify that the stream is more or
- less within expected bounds. This happens inside the OJPEGReadHeaderInfoSecStreamXxx
- functions.
-
- Some OJPEG imagery contains no valid JPEG header markers. This situation is picked
- up on if we've seen no SOF marker when we're at the start of the compressed image
- data. In this case, the tables are read from JpegXxxTables tags, and the other
- bits and pieces of information is initialized to its most basic value. This is
- implemented in the OJPEGReadHeaderInfoSecTablesXxx functions.
-
- When this is complete, a good and valid JPEG header can be assembled, and this is
- passed through to LibJpeg. When that's done, the remainder of the input stream, i.e.
- the compressed image data, can be passed through unchanged. This is done in
- OJPEGWriteStream functions.
-
- LibTiff rightly expects to know the subsampling values before decompression. Just like
- in new-style JPEG-in-TIFF, though, or even more so, actually, the YCbCrsubsampling
- tag is notoriously unreliable. To correct these tag values with the ones inside
- the JPEG stream, the first part of the input stream is pre-scanned in
- OJPEGSubsamplingCorrect, making no note of any other data, reporting no warnings
- or errors, up to the point where either these values are read, or it's clear they
- aren't there. This means that some of the data is read twice, but we feel speed
- in correcting these values is important enough to warrant this sacrifice. Allthough
- there is currently no define or other configuration mechanism to disable this behaviour,
- the actual header scanning is build to robustly respond with error report if it
- should encounter an uncorrected mismatch of subsampling values. See
- OJPEGReadHeaderInfoSecStreamSof.
-
- The restart interval and restart markers are the most tricky part... The restart
- interval can be specified in a tag. It can also be set inside the input JPEG stream.
- It can be used inside the input JPEG stream. If reading from strile data, we've
- consistenly discovered the need to insert restart markers in between the different
- striles, as is also probably the most likely interpretation of the original TIFF 6.0
- specification. With all this setting of interval, and actual use of markers that is not
- predictable at the time of valid JPEG header assembly, the restart thing may turn
- out the Achilles heel of this implementation. Fortunately, most OJPEG writer vendors
- succeed in reading back what they write, which may be the reason why we've been able
- to discover ways that seem to work.
-
- Some special provision is made for planarconfig separate OJPEG files. These seem
- to consistently contain header info, a SOS marker, a plane, SOS marker, plane, SOS,
- and plane. This may or may not be a valid JPEG configuration, we don't know and don't
- care. We want LibTiff to be able to access the planes individually, without huge
- buffering inside LibJpeg, anyway. So we compose headers to feed to LibJpeg, in this
- case, that allow us to pass a single plane such that LibJpeg sees a valid
- single-channel JPEG stream. Locating subsequent SOS markers, and thus subsequent
- planes, is done inside OJPEGReadSecondarySos.
-
- The benefit of the scheme is... that it works, basically. We know of no other that
- does. It works without checking software tag, or otherwise going about things in an
- OJPEG flavor specific manner. Instead, it is a single scheme, that covers the cases
- with and without JpegInterchangeFormat, with and without striles, with part of
- the header in JpegInterchangeFormat and remainder in first strile, etc. It is forgiving
- and robust, may likely work with OJPEG flavors we've not seen yet, and makes most out
- of the data.
-
- Another nice side-effect is that a complete JPEG single valid stream is build if
- planarconfig is not separate (vast majority). We may one day use that to build
- converters to JPEG, and/or to new-style JPEG compression inside TIFF.
-
- A dissadvantage is the lack of random access to the individual striles. This is the
- reason for much of the complicated restart-and-position stuff inside OJPEGPreDecode.
- Applications would do well accessing all striles in order, as this will result in
- a single sequential scan of the input stream, and no restarting of LibJpeg decoding
- session.

- * enough so as to not result in significant call overhead. It should be at least a few

+/* What is what, and what is not?
+
+ This decoder starts with an input stream, that is essentially the JpegInterchangeFormat
+ stream, if any, followed by the strile data, if any. This stream is read in
+ OJPEGReadByte and related functions.
+
+ It analyzes the start of this stream, until it encounters non-marker data, i.e.
+ compressed image data. Some of the header markers it sees have no actual content,
+ like the SOI marker, and APP/COM markers that really shouldn't even be there. Some
+ other markers do have content, and the valuable bits and pieces of information
+ in these markers are saved, checking all to verify that the stream is more or
+ less within expected bounds. This happens inside the OJPEGReadHeaderInfoSecStreamXxx
+ functions.
+
+ Some OJPEG imagery contains no valid JPEG header markers. This situation is picked
+ up on if we've seen no SOF marker when we're at the start of the compressed image
+ data. In this case, the tables are read from JpegXxxTables tags, and the other
+ bits and pieces of information is initialized to its most basic value. This is
+ implemented in the OJPEGReadHeaderInfoSecTablesXxx functions.
+
+ When this is complete, a good and valid JPEG header can be assembled, and this is
+ passed through to LibJpeg. When that's done, the remainder of the input stream, i.e.
+ the compressed image data, can be passed through unchanged. This is done in
+ OJPEGWriteStream functions.
+
+ LibTiff rightly expects to know the subsampling values before decompression. Just like
+ in new-style JPEG-in-TIFF, though, or even more so, actually, the YCbCrsubsampling
+ tag is notoriously unreliable. To correct these tag values with the ones inside
+ the JPEG stream, the first part of the input stream is pre-scanned in
+ OJPEGSubsamplingCorrect, making no note of any other data, reporting no warnings
+ or errors, up to the point where either these values are read, or it's clear they
+ aren't there. This means that some of the data is read twice, but we feel speed
+ in correcting these values is important enough to warrant this sacrifice. Allthough
+ there is currently no define or other configuration mechanism to disable this behaviour,
+ the actual header scanning is build to robustly respond with error report if it
+ should encounter an uncorrected mismatch of subsampling values. See
+ OJPEGReadHeaderInfoSecStreamSof.
+
+ The restart interval and restart markers are the most tricky part... The restart
+ interval can be specified in a tag. It can also be set inside the input JPEG stream.
+ It can be used inside the input JPEG stream. If reading from strile data, we've
+ consistenly discovered the need to insert restart markers in between the different
+ striles, as is also probably the most likely interpretation of the original TIFF 6.0
+ specification. With all this setting of interval, and actual use of markers that is not
+ predictable at the time of valid JPEG header assembly, the restart thing may turn
+ out the Achilles heel of this implementation. Fortunately, most OJPEG writer vendors
+ succeed in reading back what they write, which may be the reason why we've been able
+ to discover ways that seem to work.
+
+ Some special provision is made for planarconfig separate OJPEG files. These seem
+ to consistently contain header info, a SOS marker, a plane, SOS marker, plane, SOS,
+ and plane. This may or may not be a valid JPEG configuration, we don't know and don't
+ care. We want LibTiff to be able to access the planes individually, without huge
+ buffering inside LibJpeg, anyway. So we compose headers to feed to LibJpeg, in this
+ case, that allow us to pass a single plane such that LibJpeg sees a valid
+ single-channel JPEG stream. Locating subsequent SOS markers, and thus subsequent
+ planes, is done inside OJPEGReadSecondarySos.
+
+ The benefit of the scheme is... that it works, basically. We know of no other that
+ does. It works without checking software tag, or otherwise going about things in an
+ OJPEG flavor specific manner. Instead, it is a single scheme, that covers the cases
+ with and without JpegInterchangeFormat, with and without striles, with part of
+ the header in JpegInterchangeFormat and remainder in first strile, etc. It is forgiving
+ and robust, may likely work with OJPEG flavors we've not seen yet, and makes most out
+ of the data.
+
+ Another nice side-effect is that a complete JPEG single valid stream is build if
+ planarconfig is not separate (vast majority). We may one day use that to build
+ converters to JPEG, and/or to new-style JPEG compression inside TIFF.
+
+ A dissadvantage is the lack of random access to the individual striles. This is the
+ reason for much of the complicated restart-and-position stuff inside OJPEGPreDecode.
+ Applications would do well accessing all striles in order, as this will result in
+ a single sequential scan of the input stream, and no restarting of LibJpeg decoding
+ session.

- * Process library-specific flags in the open mode string.
- * The following flags may be used to control intrinsic library
- * behaviour that may or may not be desirable (usually for
- * compatibility with some application that claims to support
- * TIFF but only supports some braindead idea of what the
- * vendor thinks TIFF is):
- *
- * 'l' use little-endian byte order for creating a file
- * 'b' use big-endian byte order for creating a file
- * 'L' read/write information using LSB2MSB bit order
- * 'B' read/write information using MSB2LSB bit order
- * 'H' read/write information using host bit order
- * 'M' enable use of memory-mapped files when supported
- * 'm' disable use of memory-mapped files
- * 'C' enable strip chopping support when reading
- * 'c' disable strip chopping support
- * 'h' read TIFF header only, do not load the first IFD
- * '4' ClassicTIFF for creating a file (default)
- * '8' BigTIFF for creating a file
- *
- * The use of the 'l' and 'b' flags is strongly discouraged.
- * These flags are provided solely because numerous vendors,
- * typically on the PC, do not correctly support TIFF; they
- * only support the Intel little-endian byte order. This
- * support is not configured by default because it supports
- * the violation of the TIFF spec that says that readers *MUST*
- * support both byte orders. It is strongly recommended that
- * you not use this feature except to deal with busted apps
- * that write invalid TIFF. And even in those cases you should
- * bang on the vendors to fix their software.
- *
- * The 'L', 'B', and 'H' flags are intended for applications
- * that can optimize operations on data by using a particular
- * bit order. By default the library returns data in MSB2LSB
- * bit order for compatibiltiy with older versions of this
- * library. Returning data in the bit order of the native cpu
- * makes the most sense but also requires applications to check
- * the value of the FillOrder tag; something they probably do
- * not do right now.
- *
- * The 'M' and 'm' flags are provided because some virtual memory
- * systems exhibit poor behaviour when large images are mapped.
- * These options permit clients to control the use of memory-mapped
- * files on a per-file basis.
- *
- * The 'C' and 'c' flags are provided because the library support
- * for chopping up large strips into multiple smaller strips is not
- * application-transparent and as such can cause problems. The 'c'
- * option permits applications that only want to look at the tags,
- * for example, to get the unadulterated TIFF tag information.

+ * The following flags may be used to control intrinsic library

+ * TIFF but only supports some braindead idea of what the
+ * vendor thinks TIFF is):
+ *
+ * 'l' use little-endian byte order for creating a file
+ * 'b' use big-endian byte order for creating a file
+ * 'L' read/write information using LSB2MSB bit order
+ * 'B' read/write information using MSB2LSB bit order
+ * 'H' read/write information using host bit order
+ * 'M' enable use of memory-mapped files when supported
+ * 'm' disable use of memory-mapped files
+ * 'C' enable strip chopping support when reading
+ * 'c' disable strip chopping support
+ * 'h' read TIFF header only, do not load the first IFD
+ * '4' ClassicTIFF for creating a file (default)
+ * '8' BigTIFF for creating a file
+ *
+ * The use of the 'l' and 'b' flags is strongly discouraged.
+ * These flags are provided solely because numerous vendors,
+ * typically on the PC, do not correctly support TIFF; they
+ * only support the Intel little-endian byte order. This
+ * support is not configured by default because it supports
+ * the violation of the TIFF spec that says that readers *MUST*
+ * support both byte orders. It is strongly recommended that
+ * you not use this feature except to deal with busted apps
+ * that write invalid TIFF. And even in those cases you should
+ * bang on the vendors to fix their software.
+ *
+ * The 'L', 'B', and 'H' flags are intended for applications
+ * that can optimize operations on data by using a particular
+ * bit order. By default the library returns data in MSB2LSB
+ * bit order for compatibiltiy with older versions of this
+ * library. Returning data in the bit order of the native cpu
+ * makes the most sense but also requires applications to check
+ * the value of the FillOrder tag; something they probably do
+ * not do right now.
+ *
+ * The 'M' and 'm' flags are provided because some virtual memory
+ * systems exhibit poor behaviour when large images are mapped.
+ * These options permit clients to control the use of memory-mapped
+ * files on a per-file basis.
+ *
+ * The 'C' and 'c' flags are provided because the library support
+ * for chopping up large strips into multiple smaller strips is not
+ * application-transparent and as such can cause problems. The 'c'
+ * option permits applications that only want to look at the tags,
+ * for example, to get the unadulterated TIFF tag information.

- * TIFF Library.
- * PixarLog Compression Support
- *
- * Contributed by Dan McCoy.
- *
- * PixarLog film support uses the TIFF library to store companded
- * 11 bit values into a tiff file, which are compressed using the
- * zip compressor.
- *
- * The codec can take as input and produce as output 32-bit IEEE float values
- * as well as 16-bit or 8-bit unsigned integer values.
- *
- * On writing any of the above are converted into the internal
- * 11-bit log format. In the case of 8 and 16 bit values, the
- * input is assumed to be unsigned linear color values that represent
- * the range 0-1. In the case of IEEE values, the 0-1 range is assumed to
- * be the normal linear color range, in addition over 1 values are
- * accepted up to a value of about 25.0 to encode "hot" hightlights and such.
- * The encoding is lossless for 8-bit values, slightly lossy for the
- * other bit depths. The actual color precision should be better
- * than the human eye can perceive with extra room to allow for
- * error introduced by further image computation. As with any quantized
- * color format, it is possible to perform image calculations which
- * expose the quantization error. This format should certainly be less
- * susceptable to such errors than standard 8-bit encodings, but more
- * susceptable than straight 16-bit or 32-bit encodings.
- *
- * On reading the internal format is converted to the desired output format.
- * The program can request which format it desires by setting the internal
- * pseudo tag TIFFTAG_PIXARLOGDATAFMT to one of these possible values:
- * PIXARLOGDATAFMT_FLOAT = provide IEEE float values.
- * PIXARLOGDATAFMT_16BIT = provide unsigned 16-bit integer values
- * PIXARLOGDATAFMT_8BIT = provide unsigned 8-bit integer values
- *
- * alternately PIXARLOGDATAFMT_8BITABGR provides unsigned 8-bit integer
- * values with the difference that if there are exactly three or four channels
- * (rgb or rgba) it swaps the channel order (bgr or abgr).
- *
- * PIXARLOGDATAFMT_11BITLOG provides the internal encoding directly
- * packed in 16-bit values. However no tools are supplied for interpreting
- * these values.
- *
- * "hot" (over 1.0) areas written in floating point get clamped to
- * 1.0 in the integer data types.
- *
- * When the file is closed after writing, the bit depth and sample format
- * are set always to appear as if 8-bit data has been written into it.
- * That way a naive program unaware of the particulars of the encoding
- * gets the format it is most likely able to handle.
- *
- * The codec does it's own horizontal differencing step on the coded
- * values so the libraries predictor stuff should be turned off.
- * The codec also handle byte swapping the encoded values as necessary
- * since the library does not have the information necessary

+ * TIFF Library.
+ * PixarLog Compression Support
+ *
+ * Contributed by Dan McCoy.
+ *
+ * PixarLog film support uses the TIFF library to store companded
+ * 11 bit values into a tiff file, which are compressed using the
+ * zip compressor.
+ *
+ * The codec can take as input and produce as output 32-bit IEEE float values
+ * as well as 16-bit or 8-bit unsigned integer values.
+ *
+ * On writing any of the above are converted into the internal
+ * 11-bit log format. In the case of 8 and 16 bit values, the
+ * input is assumed to be unsigned linear color values that represent
+ * the range 0-1. In the case of IEEE values, the 0-1 range is assumed to
+ * be the normal linear color range, in addition over 1 values are
+ * accepted up to a value of about 25.0 to encode "hot" hightlights and such.
+ * The encoding is lossless for 8-bit values, slightly lossy for the
+ * other bit depths. The actual color precision should be better
+ * than the human eye can perceive with extra room to allow for
+ * error introduced by further image computation. As with any quantized
+ * color format, it is possible to perform image calculations which
+ * expose the quantization error. This format should certainly be less
+ * susceptable to such errors than standard 8-bit encodings, but more
+ * susceptable than straight 16-bit or 32-bit encodings.
+ *
+ * On reading the internal format is converted to the desired output format.
+ * The program can request which format it desires by setting the internal
+ * pseudo tag TIFFTAG_PIXARLOGDATAFMT to one of these possible values:
+ * PIXARLOGDATAFMT_FLOAT = provide IEEE float values.
+ * PIXARLOGDATAFMT_16BIT = provide unsigned 16-bit integer values
+ * PIXARLOGDATAFMT_8BIT = provide unsigned 8-bit integer values
+ *
+ * alternately PIXARLOGDATAFMT_8BITABGR provides unsigned 8-bit integer
+ * values with the difference that if there are exactly three or four channels
+ * (rgb or rgba) it swaps the channel order (bgr or abgr).
+ *
+ * PIXARLOGDATAFMT_11BITLOG provides the internal encoding directly
+ * packed in 16-bit values. However no tools are supplied for interpreting
+ * these values.
+ *
+ * "hot" (over 1.0) areas written in floating point get clamped to
+ * 1.0 in the integer data types.
+ *
+ * When the file is closed after writing, the bit depth and sample format
+ * are set always to appear as if 8-bit data has been written into it.
+ * That way a naive program unaware of the particulars of the encoding
+ * gets the format it is most likely able to handle.
+ *
+ * The codec does it's own horizontal differencing step on the coded
+ * values so the libraries predictor stuff should be turned off.
+ * The codec also handle byte swapping the encoded values as necessary
+ * since the library does not have the information necessary
+ * to know the bit depth of the raw unencoded buffer.
+ *
+ * NOTE: This decoder does not appear to update tif_rawcp, and tif_rawcc.
+ * This can cause problems with the implementation of CHUNKY_STRIP_READ_SUPPORT
+ * as noted in http://trac.osgeo.org/gdal/ticket/3894. FrankW - Jan'11

+Description:
+============
+
+WebP codec: library to encode and decode images in WebP format. This package
+contains the library that can be used in other programs to add WebP support,
+as well as the command line tools 'cwebp' and 'dwebp'.
+
+See http://developers.google.com/speed/webp
+
+Latest sources are available from http://www.webmproject.org/code/
+
+It is released under the same license as the WebM project.
+See http://www.webmproject.org/license/software/ or the
+file "COPYING" file for details. An additional intellectual
+property rights grant can be found in the file PATENTS.
+
+Building:
+=========
+
+Windows build:
+--------------
+
+By running:
+
+ nmake /f Makefile.vc CFG=release-static RTLIBCFG=static OBJDIR=output
+
+the directory output\release-static\(x64|x86)\bin will contain the tools
+cwebp.exe and dwebp.exe. The directory output\release-static\(x64|x86)\lib will
+contain the libwebp static library.
+The target architecture (x86/x64) is detected by Makefile.vc from the Visual
+Studio compiler (cl.exe) available in the system path.
+
+Unix build using makefile.unix:
+-------------------------------
+
+On platforms with GNU tools installed (gcc and make), running
+
+ make -f makefile.unix
+
+will build the binaries examples/cwebp and examples/dwebp, along
+with the static library src/libwebp.a. No system-wide installation
+is supplied, as this is a simple alternative to the full installation
+system based on the autoconf tools (see below).
+Please refer to makefile.unix for additional details and customizations.
+
+Using autoconf tools:
+---------------------
+When building from git sources, you will need to run autogen.sh to generate the
+configure script.
+
+./configure
+make
+make install
+
+should be all you need to have the following files
+
+/usr/local/include/webp/decode.h
+/usr/local/include/webp/encode.h
+/usr/local/include/webp/types.h
+/usr/local/lib/libwebp.*
+/usr/local/bin/cwebp
+/usr/local/bin/dwebp
+
+installed.
+
+Note: A decode-only library, libwebpdecoder, is available using the
+'--enable-libwebpdecoder' flag. The encode library is built separately and can
+be installed independently using a minor modification in the corresponding
+Makefile.am configure files (see comments there). See './configure --help' for
+more options.
+
+SWIG bindings:
+--------------
+
+To generate language bindings from swig/libwebp.swig at least swig-1.3
+(http://www.swig.org) is required.
+
+Currently the following functions are mapped:
+Decode:
+ WebPGetDecoderVersion
+ WebPGetInfo
+ WebPDecodeRGBA
+ WebPDecodeARGB
+ WebPDecodeBGRA
+ WebPDecodeBGR
+ WebPDecodeRGB
+
+Encode:
+ WebPGetEncoderVersion
+ WebPEncodeRGBA
+ WebPEncodeBGRA
+ WebPEncodeRGB
+ WebPEncodeBGR
+ WebPEncodeLosslessRGBA
+ WebPEncodeLosslessBGRA
+ WebPEncodeLosslessRGB
+ WebPEncodeLosslessBGR
+
+See swig/README for more detailed build instructions.
+
+Java bindings:
+
+To build the swig-generated JNI wrapper code at least JDK-1.5 (or equivalent)
+is necessary for enum support. The output is intended to be a shared object /
+DLL that can be loaded via System.loadLibrary("webp_jni").
+
+Python bindings:
+
+To build the swig-generated Python extension code at least Python 2.6 is
+required. Python < 2.6 may build with some minor changes to libwebp.swig or the
+generated code, but is untested.
+
+Encoding tool:
+==============
+
+The examples/ directory contains tools for encoding (cwebp) and
+decoding (dwebp) images.
+
+The easiest use should look like:
+ cwebp input.png -q 80 -o output.webp
+which will convert the input file to a WebP file using a quality factor of 80
+on a 0->100 scale (0 being the lowest quality, 100 being the best. Default
+value is 75).
+You might want to try the -lossless flag too, which will compress the source
+(in RGBA format) without any loss. The -q quality parameter will in this case
+control the amount of processing time spent trying to make the output file as
+small as possible.
+
+A longer list of options is available using the -longhelp command line flag:
+
+> cwebp -longhelp
+Usage:
+ cwebp [-preset <...>] [options] in_file [-o out_file]
+
+If input size (-s) for an image is not specified, it is
+assumed to be a PNG, JPEG, TIFF or WebP file.
+
+Options:
+ -h / -help ............ short help
+ -H / -longhelp ........ long help
+ -q <float> ............. quality factor (0:small..100:big)
+ -alpha_q <int> ......... transparency-compression quality (0..100)
+ -preset <string> ....... preset setting, one of:
+ default, photo, picture,
+ drawing, icon, text
+ -preset must come first, as it overwrites other parameters
+ -z <int> ............... activates lossless preset with given
+ level in [0:fast, ..., 9:slowest]
+
+ -m <int> ............... compression method (0=fast, 6=slowest)
+ -segments <int> ........ number of segments to use (1..4)
+ -size <int> ............ target size (in bytes)
+ -psnr <float> .......... target PSNR (in dB. typically: 42)
+
+ -s <int> <int> ......... input size (width x height) for YUV
+ -sns <int> ............. spatial noise shaping (0:off, 100:max)
+ -f <int> ............... filter strength (0=off..100)
+ -sharpness <int> ....... filter sharpness (0:most .. 7:least sharp)
+ -strong ................ use strong filter instead of simple (default)
+ -nostrong .............. use simple filter instead of strong
+ -partition_limit <int> . limit quality to fit the 512k limit on
+ the first partition (0=no degradation ... 100=full)
+ -pass <int> ............ analysis pass number (1..10)
+ -crop <x> <y> <w> <h> .. crop picture with the given rectangle
+ -resize <w> <h> ........ resize picture (after any cropping)
+ -mt .................... use multi-threading if available
+ -low_memory ............ reduce memory usage (slower encoding)
+ -map <int> ............. print map of extra info
+ -print_psnr ............ prints averaged PSNR distortion
+ -print_ssim ............ prints averaged SSIM distortion
+ -print_lsim ............ prints local-similarity distortion
+ -d <file.pgm> .......... dump the compressed output (PGM file)
+ -alpha_method <int> .... transparency-compression method (0..1)
+ -alpha_filter <string> . predictive filtering for alpha plane,
+ one of: none, fast (default) or best
+ -alpha_cleanup ......... clean RGB values in transparent area
+ -blend_alpha <hex> ..... blend colors against background color
+ expressed as RGB values written in
+ hexadecimal, e.g. 0xc0e0d0 for red=0xc0
+ green=0xe0 and blue=0xd0
+ -noalpha ............... discard any transparency information
+ -lossless .............. encode image losslessly
+ -hint <string> ......... specify image characteristics hint,
+ one of: photo, picture or graph
+
+ -metadata <string> ..... comma separated list of metadata to
+ copy from the input to the output if present.
+ Valid values: all, none (default), exif, icc, xmp
+
+ -short ................. condense printed message
+ -quiet ................. don't print anything
+ -version ............... print version number and exit
+ -noasm ................. disable all assembly optimizations
+ -v ..................... verbose, e.g. print encoding/decoding times
+ -progress .............. report encoding progress
+
+Experimental Options:
+ -jpeg_like ............. roughly match expected JPEG size
+ -af .................... auto-adjust filter strength
+ -pre <int> ............. pre-processing filter
+
+The main options you might want to try in order to further tune the
+visual quality are:
+ -preset
+ -sns
+ -f
+ -m
+
+Namely:
+ * 'preset' will set up a default encoding configuration targeting a
+ particular type of input. It should appear first in the list of options,
+ so that subsequent options can take effect on top of this preset.
+ Default value is 'default'.
+ * 'sns' will progressively turn on (when going from 0 to 100) some additional
+ visual optimizations (like: segmentation map re-enforcement). This option
+ will balance the bit allocation differently. It tries to take bits from the
+ "easy" parts of the picture and use them in the "difficult" ones instead.
+ Usually, raising the sns value (at fixed -q value) leads to larger files,
+ but with better quality.
+ Typical value is around '75'.
+ * 'f' option directly links to the filtering strength used by the codec's
+ in-loop processing. The higher the value, the smoother the
+ highly-compressed area will look. This is particularly useful when aiming
+ at very small files. Typical values are around 20-30. Note that using the
+ option -strong/-nostrong will change the type of filtering. Use "-f 0" to
+ turn filtering off.
+ * 'm' controls the trade-off between encoding speed and quality. Default is 4.
+ You can try -m 5 or -m 6 to explore more (time-consuming) encoding
+ possibilities. A lower value will result in faster encoding at the expense
+ of quality.
+
+Decoding tool:
+==============
+
+There is a decoding sample in examples/dwebp.c which will take
+a .webp file and decode it to a PNG image file (amongst other formats).
+This is simply to demonstrate the use of the API. You can verify the
+file test.webp decodes to exactly the same as test_ref.ppm by using:
+
+ cd examples
+ ./dwebp test.webp -ppm -o test.ppm
+ diff test.ppm test_ref.ppm
+
+The full list of options is available using -h:
+
+> dwebp -h
+Usage: dwebp in_file [options] [-o out_file]
+
+Decodes the WebP image file to PNG format [Default]
+Use following options to convert into alternate image formats:

+Visualization tool:
+===================
+
+There's a little self-serve visualization tool called 'vwebp' under the
+examples/ directory. It uses OpenGL to open a simple drawing window and show
+a decoded WebP file. It's not yet integrated in the automake build system, but
+you can try to manually compile it using the recommendations below.
+
+Usage: vwebp in_file [options]
+
+Decodes the WebP image file and visualize it using OpenGL
+Options are:
+ -version .... print version number and exit
+ -noicc ....... don't use the icc profile if present
+ -nofancy ..... don't use the fancy YUV420 upscaler
+ -nofilter .... disable in-loop filtering
+ -dither <int> dithering strength (0..100), default=50
+ -noalphadither disable alpha plane dithering
+ -mt .......... use multi-threading

+
+Encoding API:
+=============
+
+The main encoding functions are available in the header src/webp/encode.h
+The ready-to-use ones are:
+size_t WebPEncodeRGB(const uint8_t* rgb, int width, int height, int stride,
+ float quality_factor, uint8_t** output);
+size_t WebPEncodeBGR(const uint8_t* bgr, int width, int height, int stride,
+ float quality_factor, uint8_t** output);
+size_t WebPEncodeRGBA(const uint8_t* rgba, int width, int height, int stride,
+ float quality_factor, uint8_t** output);
+size_t WebPEncodeBGRA(const uint8_t* bgra, int width, int height, int stride,
+ float quality_factor, uint8_t** output);
+
+They will convert raw RGB samples to a WebP data. The only control supplied
+is the quality factor.
+
+There are some variants for using the lossless format:
+
+size_t WebPEncodeLosslessRGB(const uint8_t* rgb, int width, int height,
+ int stride, uint8_t** output);
+size_t WebPEncodeLosslessBGR(const uint8_t* bgr, int width, int height,
+ int stride, uint8_t** output);
+size_t WebPEncodeLosslessRGBA(const uint8_t* rgba, int width, int height,
+ int stride, uint8_t** output);
+size_t WebPEncodeLosslessBGRA(const uint8_t* bgra, int width, int height,
+ int stride, uint8_t** output);
+
+Of course in this case, no quality factor is needed since the compression
+occurs without loss of the input values, at the expense of larger output sizes.
+
+Advanced encoding API:
+----------------------
+
+A more advanced API is based on the WebPConfig and WebPPicture structures.
+
+WebPConfig contains the encoding settings and is not tied to a particular
+picture.
+WebPPicture contains input data, on which some WebPConfig will be used for
+compression.
+The encoding flow looks like:
+
+-------------------------------------- BEGIN PSEUDO EXAMPLE
+
+#include <webp/encode.h>
+
+ // Setup a config, starting form a preset and tuning some additional
+ // parameters
+ WebPConfig config;
+ if (!WebPConfigPreset(&config, WEBP_PRESET_PHOTO, quality_factor))
+ return 0; // version error
+ }
+ // ... additional tuning
+ config.sns_strength = 90;
+ config.filter_sharpness = 6;
+ config_error = WebPValidateConfig(&config); // not mandatory, but useful
+
+ // Setup the input data
+ WebPPicture pic;
+ if (!WebPPictureInit(&pic)) {
+ return 0; // version error
+ }
+ pic.width = width;
+ pic.height = height;
+ // allocated picture of dimension width x height
+ if (!WebPPictureAllocate(&pic)) {
+ return 0; // memory error
+ }
+ // at this point, 'pic' has been initialized as a container,
+ // and can receive the Y/U/V samples.
+ // Alternatively, one could use ready-made import functions like
+ // WebPPictureImportRGB(), which will take care of memory allocation.
+ // In any case, past this point, one will have to call
+ // WebPPictureFree(&pic) to reclaim memory.
+
+ // Set up a byte-output write method. WebPMemoryWriter, for instance.
+ WebPMemoryWriter wrt;
+ WebPMemoryWriterInit(&wrt); // initialize 'wrt'
+
+ pic.writer = MyFileWriter;
+ pic.custom_ptr = my_opaque_structure_to_make_MyFileWriter_work;
+
+ // Compress!
+ int ok = WebPEncode(&config, &pic); // ok = 0 => error occurred!
+ WebPPictureFree(&pic); // must be called independently of the 'ok' result.
+
+ // output data should have been handled by the writer at that point.
+ // -> compressed data is the memory buffer described by wrt.mem / wrt.size
+
+ // deallocate the memory used by compressed data
+ WebPMemoryWriterClear(&wrt);
+
+-------------------------------------- END PSEUDO EXAMPLE
+
+Decoding API:
+=============
+
+This is mainly just one function to call:
+
+#include "webp/decode.h"
+uint8_t* WebPDecodeRGB(const uint8_t* data, size_t data_size,
+ int* width, int* height);
+
+Please have a look at the file src/webp/decode.h for the details.
+There are variants for decoding in BGR/RGBA/ARGB/BGRA order, along with
+decoding to raw Y'CbCr samples. One can also decode the image directly into a
+pre-allocated buffer.
+
+To detect a WebP file and gather the picture's dimensions, the function:
+ int WebPGetInfo(const uint8_t* data, size_t data_size,
+ int* width, int* height);
+is supplied. No decoding is involved when using it.
+
+Incremental decoding API:
+=========================
+
+In the case when data is being progressively transmitted, pictures can still
+be incrementally decoded using a slightly more complicated API. Decoder state
+is stored into an instance of the WebPIDecoder object. This object can be
+created with the purpose of decoding either RGB or Y'CbCr samples.
+For instance:
+
+ WebPDecBuffer buffer;
+ WebPInitDecBuffer(&buffer);
+ buffer.colorspace = MODE_BGR;
+ ...
+ WebPIDecoder* idec = WebPINewDecoder(&buffer);
+
+As data is made progressively available, this incremental-decoder object
+can be used to decode the picture further. There are two (mutually exclusive)
+ways to pass freshly arrived data:
+
+either by appending the fresh bytes:
+
+ WebPIAppend(idec, fresh_data, size_of_fresh_data);
+
+or by just mentioning the new size of the transmitted data:
+
+ WebPIUpdate(idec, buffer, size_of_transmitted_buffer);
+
+Note that 'buffer' can be modified between each call to WebPIUpdate, in
+particular when the buffer is resized to accommodate larger data.
+
+These functions will return the decoding status: either VP8_STATUS_SUSPENDED if
+decoding is not finished yet or VP8_STATUS_OK when decoding is done. Any other
+status is an error condition.
+
+The 'idec' object must always be released (even upon an error condition) by
+calling: WebPDelete(idec).
+
+To retrieve partially decoded picture samples, one must use the corresponding
+method: WebPIDecGetRGB or WebPIDecGetYUVA.
+It will return the last displayable pixel row.
+
+Lastly, note that decoding can also be performed into a pre-allocated pixel
+buffer. This buffer must be passed when creating a WebPIDecoder, calling
+WebPINewRGB() or WebPINewYUVA().
+
+Please have a look at the src/webp/decode.h header for further details.
+
+Advanced Decoding API:
+======================
+
+WebP decoding supports an advanced API which provides on-the-fly cropping and
+rescaling, something of great usefulness on memory-constrained environments like
+mobile phones. Basically, the memory usage will scale with the output's size,
+not the input's, when one only needs a quick preview or a zoomed in portion of
+an otherwise too-large picture. Some CPU can be saved too, incidentally.
+
+-------------------------------------- BEGIN PSEUDO EXAMPLE
+ // A) Init a configuration object
+ WebPDecoderConfig config;
+ CHECK(WebPInitDecoderConfig(&config));
+
+ // B) optional: retrieve the bitstream's features.
+ CHECK(WebPGetFeatures(data, data_size, &config.input) == VP8_STATUS_OK);
+
+ // C) Adjust 'config' options, if needed
+ config.options.no_fancy_upsampling = 1;
+ config.options.use_scaling = 1;
+ config.options.scaled_width = scaledWidth();
+ config.options.scaled_height = scaledHeight();
+ // etc.
+
+ // D) Specify 'config' output options for specifying output colorspace.
+ // Optionally the external image decode buffer can also be specified.
+ config.output.colorspace = MODE_BGRA;
+ // Optionally, the config.output can be pointed to an external buffer as
+ // well for decoding the image. This externally supplied memory buffer
+ // should be big enough to store the decoded picture.
+ config.output.u.RGBA.rgba = (uint8_t*) memory_buffer;
+ config.output.u.RGBA.stride = scanline_stride;
+ config.output.u.RGBA.size = total_size_of_the_memory_buffer;
+ config.output.is_external_memory = 1;
+
+ // E) Decode the WebP image. There are two variants w.r.t decoding image.
+ // The first one (E.1) decodes the full image and the second one (E.2) is
+ // used to incrementally decode the image using small input buffers.
+ // Any one of these steps can be used to decode the WebP image.
+
+ // E.1) Decode full image.
+ CHECK(WebPDecode(data, data_size, &config) == VP8_STATUS_OK);
+
+ // E.2) Decode image incrementally.
+ WebPIDecoder* const idec = WebPIDecode(NULL, NULL, &config);
+ CHECK(idec != NULL);
+ while (bytes_remaining > 0) {
+ VP8StatusCode status = WebPIAppend(idec, input, bytes_read);
+ if (status == VP8_STATUS_OK || status == VP8_STATUS_SUSPENDED) {
+ bytes_remaining -= bytes_read;
+ } else {
+ break;
+ }
+ }
+ WebPIDelete(idec);
+
+ // F) Decoded image is now in config.output (and config.output.u.RGBA).
+ // It can be saved, displayed or otherwise processed.
+
+ // G) Reclaim memory allocated in config's object. It's safe to call
+ // this function even if the memory is external and wasn't allocated
+ // by WebPDecode().
+ WebPFreeDecBuffer(&config.output);

+ where: 'file_i' is the i'th animation frame (WebP format),
+ 'di' is the pause duration before next frame,
+ 'xi','yi' specify the image offset for this frame,
+ 'mi' is the dispose method for this frame (0 or 1),
+ 'bi' is the blending method for this frame (+b or -b)
+
+LOOP_COUNT:
+ Number of times to repeat the animation.
+ Valid range is 0 to 65535 [Default: 0 (infinite)].
+
+BACKGROUND_COLOR:
+ Background color of the canvas.
+ A,R,G,B
+ where: 'A', 'R', 'G' and 'B' are integers in the range 0 to 255 specifying
+ the Alpha, Red, Green and Blue component values respectively
+ [Default: 255,255,255,255]
+
+INPUT & OUTPUT are in WebP format.
+
+Note: The nature of EXIF, XMP and ICC data is not checked and is assumed to be
+valid.
+
+Visualization tool:
+===================
+
+The examples/ directory also contains a tool (vwebp) for viewing WebP files.
+It decodes the image and visualizes it using OpenGL. See the libwebp README
+for details on building and running this program.
+
+Mux API:
+========
+The Mux API contains methods for adding data to and reading data from WebP
+files. This API currently supports XMP/EXIF metadata, ICC profile and animation.
+Other features may be added in subsequent releases.
+
+Example#1 (pseudo code): Creating a WebPMux object with image data, color
+profile and XMP metadata.
+
+ int copy_data = 0;
+ WebPMux* mux = WebPMuxNew();
+ // ... (Prepare image data).
+ WebPMuxSetImage(mux, &image, copy_data);
+ // ... (Prepare ICC profile data).
+ WebPMuxSetChunk(mux, "ICCP", &icc_profile, copy_data);
+ // ... (Prepare XMP metadata).
+ WebPMuxSetChunk(mux, "XMP ", &xmp, copy_data);
+ // Get data from mux in WebP RIFF format.
+ WebPMuxAssemble(mux, &output_data);
+ WebPMuxDelete(mux);
+ // ... (Consume output_data; e.g. write output_data.bytes to file).
+ WebPDataClear(&output_data);
+
+
+Example#2 (pseudo code): Get image and color profile data from a WebP file.
+
+ int copy_data = 0;
+ // ... (Read data from file).
+ WebPMux* mux = WebPMuxCreate(&data, copy_data);
+ WebPMuxGetFrame(mux, 1, &image);
+ // ... (Consume image; e.g. call WebPDecode() to decode the data).
+ WebPMuxGetChunk(mux, "ICCP", &icc_profile);
+ // ... (Consume icc_profile).
+ WebPMuxDelete(mux);
+ free(data);
+
+
+For a detailed Mux API reference, please refer to the header file
+(src/webp/mux.h).
+
+Demux API:
+==========
+The Demux API enables extraction of images and extended format data from
+WebP files. This API currently supports reading of XMP/EXIF metadata, ICC
+profile and animated images. Other features may be added in subsequent
+releases.
+
+Code example: Demuxing WebP data to extract all the frames, ICC profile
+and EXIF/XMP metadata.
+
+ WebPDemuxer* demux = WebPDemux(&webp_data);
+ uint32_t width = WebPDemuxGetI(demux, WEBP_FF_CANVAS_WIDTH);
+ uint32_t height = WebPDemuxGetI(demux, WEBP_FF_CANVAS_HEIGHT);
+ // ... (Get information about the features present in the WebP file).
+ uint32_t flags = WebPDemuxGetI(demux, WEBP_FF_FORMAT_FLAGS);
+
+ // ... (Iterate over all frames).
+ WebPIterator iter;
+ if (WebPDemuxGetFrame(demux, 1, &iter)) {
+ do {
+ // ... (Consume 'iter'; e.g. Decode 'iter.fragment' with WebPDecode(),
+ // ... and get other frame properties like width, height, offsets etc.
+ // ... see 'struct WebPIterator' below for more info).
+ } while (WebPDemuxNextFrame(&iter));
+ WebPDemuxReleaseIterator(&iter);
+ }
+
+ // ... (Extract metadata).
+ WebPChunkIterator chunk_iter;
+ if (flags & ICCP_FLAG) WebPDemuxGetChunk(demux, "ICCP", 1, &chunk_iter);
+ // ... (Consume the ICC profile in 'chunk_iter.chunk').
+ WebPDemuxReleaseChunkIterator(&chunk_iter);
+ if (flags & EXIF_FLAG) WebPDemuxGetChunk(demux, "EXIF", 1, &chunk_iter);
+ // ... (Consume the EXIF metadata in 'chunk_iter.chunk').
+ WebPDemuxReleaseChunkIterator(&chunk_iter);
+ if (flags & XMP_FLAG) WebPDemuxGetChunk(demux, "XMP ", 1, &chunk_iter);
+ // ... (Consume the XMP metadata in 'chunk_iter.chunk').
+ WebPDemuxReleaseChunkIterator(&chunk_iter);
+ WebPDemuxDelete(demux);
+
+
+For a detailed Demux API reference, please refer to the header file
+(src/webp/demux.h).
+
+AnimEncoder API:
+================
+The AnimEncoder API can be used to create animated WebP images.
+
+Code example:
+
+ WebPAnimEncoderOptions enc_options;
+ WebPAnimEncoderOptionsInit(&enc_options);
+ // ... (Tune 'enc_options' as needed).
+ WebPAnimEncoder* enc = WebPAnimEncoderNew(width, height, &enc_options);
+ while(<there are more frames>) {
+ WebPConfig config;
+ WebPConfigInit(&config);
+ // ... (Tune 'config' as needed).
+ WebPAnimEncoderAdd(enc, frame, duration, &config);
+ }
+ WebPAnimEncoderAssemble(enc, webp_data);
+ WebPAnimEncoderDelete(enc);
+ // ... (Write the 'webp_data' to a file, or re-mux it further).
+
+
+For a detailed AnimEncoder API reference, please refer to the header file
+(src/webp/mux.h).

+// inline YUV<->RGB conversion function

+// The exact naming is Y'CbCr, following the ITU-R BT.601 standard.

+// Y = 0.2569 * R + 0.5044 * G + 0.0979 * B + 16
+// U = -0.1483 * R - 0.2911 * G + 0.4394 * B + 128
+// V = 0.4394 * R - 0.3679 * G - 0.0715 * B + 128
+// We use 16bit fixed point operations for RGB->YUV conversion (YUV_FIX).
+//
+// For the Y'CbCr to RGB conversion, the BT.601 specification reads:
+// R = 1.164 * (Y-16) + 1.596 * (V-128)
+// G = 1.164 * (Y-16) - 0.813 * (V-128) - 0.391 * (U-128)
+// B = 1.164 * (Y-16) + 2.018 * (U-128)
+// where Y is in the [16,235] range, and U/V in the [16,240] range.
+// In the table-lookup version (WEBP_YUV_USE_TABLE), the common factor
+// "1.164 * (Y-16)" can be handled as an offset in the VP8kClip[] table.
+// So in this case the formulae should read:
+// R = 1.164 * [Y + 1.371 * (V-128) ] - 18.624
+// G = 1.164 * [Y - 0.698 * (V-128) - 0.336 * (U-128)] - 18.624
+// B = 1.164 * [Y + 1.733 * (U-128)] - 18.624
+// once factorized.
+// For YUV->RGB conversion, only 14bit fixed precision is used (YUV_FIX2).
+// That's the maximum possible for a convenient ARM implementation.

+Class MapIntrospector - STL std::map Introspector
+
+The MapIntrospector is a helper class used to calculate or estimate part
+of the internal memory footprint of a std::map, that is the memory used
+by N entries, where N is provided as an argument. This class is used by
+function FreeImage_GetMemorySize, which aims to get the total memory
+usage for a FreeImage bitmap.
+
+The type argument _Maptype must take the type of the std::map to be
+introspected.
+
+This class accounts for 'internal' memory per entry only, that is, the
+size returned does neither include the actual size of the std::map class
+itself, nor does it include the size of referenced keys and values (also
+the actual bytes required for std::string type keys or values are not
+counted). For example, the total memory usage should be something like:
+
+typedef std::map<std::string, double> DBLMAP
+DBLMAP MyMap;
+
+int total_size = sizeof(DBLMAP) + MapIntrospector<DBLMAP>::GetNodesMemorySize(MyMap.size())
+for (DBLMAP::iterator i = MyMap->begin(); i != MyMap->end(); i++) {
+ std::string key = i->first;
+ total_size += key.capacity();
+}
+
+So, basically, this class' task is to get the (constant) number of bytes
+per entry, which is multiplied by N (parameter node_count) and returned
+in method GetNodesMemorySize. Since this heavily depends on the actually
+used C++ Standard Library, this class must be implemented specifically
+for each C++ Standard Library.
+
+At current, there is an implementation available for these C++ Standard
+Libraries:
+
+- Microsoft C++ Standard Library
+- GNU Standard C++ Library v3, libstdc++-v3
+- LLVM "libc++" C++ Standard Library (untested)
+- Unknown C++ Standard Library
+
+Volunteers for testing as well as for providing support for other/new
+libraries are welcome.
+
+The 'Unknown C++ Standard Library' case is used if no other known C++
+Standard Library was detected. It uses a typical _Node structure to
+declare an estimated memory consumption for a node.
+*/
+
+#if defined(_CPPLIB_VER) // Microsoft C++ Standard Library
+/**
+ The Microsoft C++ Standard Library uses the protected structure _Node
+ of class std::_Tree_nod to represent a node. This class is used by
+ std::_Tree, the base class of std::map. So, since std::map is derived
+ from std::_Tree (and _Node is protected), we can get access to this
+ structure by deriving from std::map.
+
+ Additionally, the Microsoft C++ Standard Library uses a separately
+ allocated end node for its balanced red-black tree so, actually, there
+ are size() + 1 nodes present in memory.
+
+ With all that in place, the total memory for all nodes in std::map

Note on multi-threaded applications :
-
-The singleton pattern must be carefully constructed in multi-threaded applications.
-If two threads are to execute the creation method at the same time when a singleton
-does not yet exist, they both must check for an instance of the singleton and then
-only one should create the new one.
-The classic solution to this problem is to use mutual exclusion on the class that
-indicates that the object is being instantiated.
-The FreeImage solution is to instantiate the singleton before any other thread is launched,

-Version 1.0.3
- * Added support for enabling/disabling large stack optimisations, used in
- halfFunction.h.
- (Piotr Stanczyk)
- * Added ImathNoise.(h/cpp) files. Initializes Perlin noise to match the
- Renderman implmenetation.
- (Pixar Contribution)
- * Fixed a number of missing includes to comply with stricter
- enforcement by gnu compilers.
- (Piotr Stanczyk)
- * Depracated compiler flag: -Wno-long-double since it is no longer
- supported under OS X.
- (Piotr Stanczyk)
- * A minor API change to Imath::Frustum has been made: the functions
- 'near' and 'far' have been renamed to 'nearPlane' and 'farPlane' due
- to conflicts with certain windows headers. The former alternate
- accessor names for these values on windows ('hither' and 'yon')
- remain, though should be considered deprecated.
- (David Lenihan)
- * Added SVD, eigenvalue solver, and procrustes fit calculations
- to ImathMatrixAlgo.
- (Chris Twigg, Ji Hun Yu)
- * Added Imath::FrustumTest for frustum visibility testing.
- (Eric Johnston)
- * Fixed a stack corruption in the matrix minorOf functions.
- (Nick Rasmussen)
- * Visual studio 2008 project files have been added to the vc/vc9
- directory, and several minor visual studio compile fixes have
- been applied.
- (Nick Rasmussen)
- * Updated the so verison to 7.
- (Piotr Stanczyk)
- * Depracated the MacCode_Warrior and Shake submodules.
- (Piotr Stanczyk)
-
-Version 1.0.2
- * Added support for targetting builds on 64bit Windows and minimising
- number of compiler warnings on Windows. Thanks to Ger Hobbelt for his
- contributions to CreateDLL.
- (Ji Hun Yu)
- * Removed a spurious restrict qualifier in the matrix manipulation code
- that was causing the 64-bit MS compiler to generate code in release
- mode that caused incorrect results.
- (Ji Hun Yu)
- * Added patches for improving universal binaries on OS X. Thanks to
- Paul Schneider for the contribution
- (Piotr Stanczyk)
- * Imath::Box optimization: remove loops from methods by partially
- specializing the class, for boxes of two and three dimensions.
- (Piotr Stanczyk)
- * Added explicit copy constructors to Imath::Matrix33<T> and
- ImathMatrix44<T> to make conversions between float and double
- matrices more convenient.
- (Florian Kainz)
- * Added slerpShortestArc() and euclideanInnerProduct() functions
- to Imath::Quat<T>.
- (Nick Porcino)
- * Added 4D vector class template Imath::Vec4<T>.
- (Nick Porcino)
- * Copy constructors and assignment operators for Matrix33<T>
- and Matrix44<T> are up to 25% faster. Added matrix constructors
- that do not initialize the matrix (this is faster in cases where
- the initial value of the matrix is immediately overwritten anyway).
- (Nick Porcino)
- * Rewrote function closestPointOnBox(point,box). Shortened
- the code, improved numerical accuracy, fixed a bug where
- closestPointOnBox(box.center(),box) would return the center
- of the +Z side of the box, even if the +/-X or +/-Y sides
- were closer.
- (Florian Kainz)
- * Rewrote function findEntryAndExitPoints() in ImathBoxAlgo.h.
- Results are now consistent with those from intersect(), also
- in ImathBoxAlgo.h.
- (Florian Kainz)
- * Made Vec2<T>::length() and Vec3<T>::length() more accurate for
- vectors whose length is less than sqrt(limits<T>::smallest());
- (Florian Kainz)
- * Made Quat<T>::angle() more accurate for small angles.
- (Don Hatch)
-
-Version 1.0.1:
- * Removed Windows .suo files from distribution.
- (Eric Wimmer)
-
-Version 1.0.0:
- * Bumped DSO version number to 6.0
- (Florian Kainz)
- * Rounding during float-to-half conversion now implements
- "round to nearest even" mode: if the original float value
- is exactly in the middle between the two closest half values
- then rounding chooses the half value whose least significant
- bit is zero.
- (Florian Kainz)
- * Installation Tuning:
- - Corrected version number on dso's (libtool) - now 5.0
- - Separated ILMBASE_LDFLAGS and ILMBASE_LIBS so that test programs
- in configure scripts of packages dependent on IlmBase can link
- with static libraries properly
- - eliminated some warning messages during install
- (Andrew Kunz)
-
-Version 0.9.0:

-IlmBase on MacOS X
-------------------
-
-Building IlmBase on MacOS X is just like building it on GNU/Linux.
-Follow the instructions in the README file under BUILDLING ILMBASE,
-but see below re: shared libraries.
-
-
-Universal Builds on Mac OS X
-------------------
-OS X supports multiple architectures. By default, IlmBase will be built
-for the system doing the building. For example, if you build IlmBase on
-an Intel system, the libraries will be built for Intel.
-
-You can specify building for a different architecture, or multiple architectures,
-by passing the "--enable-osx-arch" flag to configure. Building for multiple
-architectures requires that "--disable-dependency-tracking" be passed as well.
-
-For example, to build for Intel and PowerPC:
-
-./configure --enable-osx-arch="i386 ppc" --disable-dependency-tracking.
-
-To build "4-way universal" for 32-bit and 64-bit Intel and PowerPC:
-
-./configure --enable-osx-arch="i386 ppc x86_64 ppc64" --disable-dependency-tracking.
-
-For more information on universal builds, see:
-
-http://developer.apple.com/documentation/Porting/Conceptual/PortingUNIX/compiling/chapter_4_section_3.html
-
-Earlier releases of IlmBase included an "--enable-osx-universal-binaries"
-switch, which specifies a two-way universal build: Intel and PowerPC, 32-bit only.
-This is still available, but deprecated in favor of the more flexible
-"--enable-osx-arch" and "--enable-osx-sdk" switches.
-
-
-Choosing an SDK on Mac OS X
-------------------
-OS X allows you to specify one of several SDKs, or sysroots. This allows you to
-target systems other than the system that your build machine runs.
-
-For example, if you are building on Mac OS X 10.4, but you need access to features
-that were introduced in Mac OS X 10.5, you can build against the Mac OS X 10.5
-versions of system libraries and headers.
-
-You can choose to build IlmBase with a specific SDK using the "--enable-osx-sdk"
-switch. For example:
-
-./configure --enable-osx-sdk=MacOSX10.5.sdk
-
-If you are building on Mac OS X 10.4 and want to build universal, you will need to
-specify the universal version of the 10.4 SDK: MacOSX10.4u.sdk. Otherwise, you probably
-don't need to specify an SDK.
-
-For more information on sysroots, see:
-
-http://developer.apple.com/documentation/DeveloperTools/gcc-4.2.1/gcc/Directory-Options.html
-
-
-Shared libraries
-----------------
-
-IlmBase requires the "flat namespace" option when built as a shared
-library. You may have problems trying to use IlmBase shared libraries
-with applications that expect OS X's two-level namespace. We have not
-tested the shared libs extensively, though they appear to work with
-exrdisplay and exrheader, but use them at your own risk. We will
-support two-level namespace shared libs in a future release.
+IlmBase on MacOS X
+------------------
+
+Building IlmBase on MacOS X is just like building it on GNU/Linux.
+Follow the instructions in the README file under BUILDLING ILMBASE,
+but see below re: shared libraries.
+
+
+Missing gnu automake tools on Mac OS X 10.8+
+------------------
+Later versions of OS X ,10.8+, do not, by default have all the necessary
+tools for building. In particular, Autoconf and Automake may be missing.
+
+The following commands will download and install the necessary components:
+
+cd ~/myDevLoc
+curl -OL http://ftpmirror.gnu.org/autoconf/autoconf-2.64.tar.gz
+tar xzf autoconf-2.64.tar.gz
+cd autoconf-2.64
+./configure --prefix=~/myDevLoc/autotools-bin
+make; make install
+
+cd ~/myDevLoc
+curl -OL http://ftpmirror.gnu.org/automake/automake-1.12.tar.gz
+tar xzf automake-1.12.tar.gz
+cd automake-1.12
+./configure --prefix=~/myDevLoc/autotools-bin
+make; make install
+
+cd ~/myDevLoc
+curl -OL http://ftpmirror.gnu.org/libtool/libtool-2.4.tar.gz
+tar xzf libtool-2.4.tar.gz
+cd libtool-2.4
+./configure --prefix=~/myDevLoc/autotools-bin
+make; make install
+
+
+You may want to export the installation path for your convenience.
+Finally, make sure that you have installed the command line tools for XCode.
+
+
+Universal Builds on Mac OS X
+------------------
+OS X supports multiple architectures. By default, IlmBase will be built
+for the system doing the building. For example, if you build IlmBase on
+an Intel system, the libraries will be built for Intel.
+
+You can specify building for a different architecture, or multiple architectures,
+by passing the "--enable-osx-arch" flag to configure. Building for multiple
+architectures requires that "--disable-dependency-tracking" be passed as well.
+
+For example, to build for Intel and PowerPC:
+
+./configure --enable-osx-arch="i386 ppc" --disable-dependency-tracking.
+
+To build "4-way universal" for 32-bit and 64-bit Intel and PowerPC:
+
+./configure --enable-osx-arch="i386 ppc x86_64 ppc64" --disable-dependency-tracking.
+

+------------------------------------------------
+ On the use of namespace in IlmBase and OpenEXR
+------------------------------------------------
+
+v2.0 of the code base introduces user configurable namespaces for
+component libraries. This addition introduces the ability to deal with
+multiple versions of these libraries loaded at runtime.
+An example case:
+ Application is built with OpenEXR v1.7, but the required plugin
+ requires functionality from OpenEXR v2.0.
+
+ By injecting the version number into the (mangled) symbols, via
+ the namespacing mechanism, and changing the soname, via the build
+ system, the developer can link his plugin against the v2.0 library
+ At run time the dynamic linker can load both the 1.7 and 2.0
+ versions of the library since the library soname are different and
+ the symbols are different.
+
+
+When building IlmBase or OpenEXR the following configure script options
+are available:
+ --enable-namespaceversioning
+and
+ --enable-customusernamespace
+
+
+
+-- Internal Library Namespace
+The option, --enable-namespaceversioning, controls the namespace that
+is used in the library. Without an argument (see below) the library
+will be built with a suffix made up of the major and minor versions.
+For example, for version 2.0.0, the internal library namespaces will be
+Imath_2_0, Iex_2_0, IlmThread_2_0 etc
+
+For additional flexibility and control, this option can take an additional
+argument in which case the internal library namespace will be suffixed
+accordingly.
+For example:
+ ./configure --enable-namespaceversioning=ILM
+will result in the namespaces of the type Imath_ILM, Iex_ILM etc.
+
+This can be useful for completely isolating your local build.
+
+Code using the library should continue to use the namespace Imath, or for
+greater portability IMATH_NAMESPACE, to refer to objects in libImath.
+In particular, the explicit use of the internal namespace is discouraged.
+This ensures that code will continue to compile with customised or future
+versions of the library, which may have a different internal namespace.
+
+Similarily, for other namespaces in the libraries: Iex, IlmThread and IlmImf.
+
+Note that this scheme allows existing code to compile without modifications,
+since the 'old' namespaces Imath, Iex, IlmThread and IlmImf continue to be
+available, albeit in a slightly different form.
+This is achieved via the following, in the Imath case:
+ namespace IMATH_INTERNAL_NAMESPACE {}
+ namespace IMATH_NAMESPACE
+ {
+ using namespace IMATH_INTERNAL_NAMESPACE;
+ }
+This is included in all header files in the Imath library and similar ones
+are present for the libraries Iex, IlmThread and IlmImf.
+
+The only exception to this is where user code has forward declarations of
+objects in the Imf namespace, as these will forward declare symbols in an
+incorrect namespace
+These forward declarations should be removed, and replaced with
+ #include <ImfForward.h>,
+which forward-declares all types correctly.
+
+
+
+-- Public/User Library Namespace
+The option, --enable-customusernamespace, can override the namespace into
+which we will 'export' the internal namespace. This takes an argument
+that sets the name of the custom user namespace.
+In the example above, IMATH_NAMESPACE could be resolved into something other
+than Imath, say Imath_MySpecialNamespace.
+
+In nearly all cases, this will not be used as per the above discussion
+regarding code compatibility.
+Its presence is to provide a mechanism for not prohibiting the case when
+the application must pass objects from two different versions of the library.

-in the path that corresponds to your the version of Visual Studio.
-
-The Visual Studio project files assume, and help build out, a directory
-called "Deploy". In the end, this directory will contain the objects
-that might then be moved away from the source for general running of the
-compiled programs. The directory structure at the end of compiling all
-the related tools looks like this:
-
-Deploy
- include
- lib
- Debug
- Release
- bin
- Debug
- Release
-openexr-cvs (name as desired)
- IlmBase
- PyIlmBase
- OpenEXR
- OpenEXR_Viewers
-ctl-cvs (name as desired)
- CTL
- OpenEXR_CTL
-fltk
- FL
- GL
- lib
-nvidia
- include
- GL
- glh
- lib
-
-If OpenEXR_Viewers is not being compiled, then fltk and nvidia will
-not be needed, but that will be covered later.
-
-Step 1. Compile IlmBase
-
- a. Point Visual Studio at the .sln file in vc\<vc7|8>\IlmBase in the
- IlmBase subdirectory
-
- b. Select the Release configuration and hit Build Solution. This
- will create the Deploy directory, and copy the relevant parts to it.
-
- c. If the debug versions are desired, select the Debug configuration
- and hit Build Solution. This will add the Debug directories to Deploy.
-
-Step 2. Compile OpenEXR support
-
- a. Retrieve the zlib binaries. The project files are set up to link
- against the dll version of zlib, but can easily be changed to link
- against a static version, or a self-built version if desired.
-
- 1. Go to http://www.zlib.net and download the precompiled DLL
- version of zlib (as of writing, zlib123-dll.zip)
-
- 2. If you don't wish to put the files into your MS visual studio
- directories and install the dll into windows\system32:
-
- a. Put a copy of zlib1.dll into Deploy\bin\Release and
- Deploy\bin\Debug
-
- b. Copy the header files into Deploy\include
-
- c. Copy zdll.lib and zdll.exp into Deploy\lib\Release and
- Deploy\lib\Debug
-
- b. Open the Visual Studio project in OpenEXR\vc\<vc7|8>\OpenEXR.
-
- c. Select the Release configuration and build. The IlmImfTest
- program runs a confidence test of your build to make sure
- it is able to work, and may take some time to complete.
-
- d. Optionally select the Debug configuration and build.
-
-Step 3. Compile CTL support
-
- a. Open the Visual Studio project in CTL\vc\<vc7|8>\CTL.
-
- b. Select the Release configuration and build. The IlmCtlTest
- program runs a confidence test of your build to make sure it is
- able to work, and may take some time to complete.
-
- c. Optionally select the Debug configuration and build.
-
-Step 4. Compile OpenEXR_CTL support
-
- a. Open the Visual Studio project in OpenEXR_CTL\vc\<vc7|8>\OpenEXR_CTL.
-
- b. Select the Release configuration and build.
-
- c. Optionally select the Debug configuration and build.
-
-Step 5. Compile OpenEXR_Viewers
-
- a. Open the appropriate Visual Studio project in
- OpenEXR_Viewers\vc\<vc7|8>\OpenEXR_Viewers depending on whether or not
- you want CTL support.
-
- b. exrdisplay requires fltk to work.
-
- 1. Go to http://www.fltk.org and download fltk 1.1.7
-
- 2. Open its project files and compile using the instructions they
- provide.
-
- 3. Create the fltk directory at the top level of your directory
- structure as presented above and copy the FL, GL, and lib folders
- into the fltk directory
-
- 4. exrdisplay links fltk statically, so no dll is needed.
-
- c. playexr requires the nvidia cg library as well as glut and glew.
-
- 1. Setup the cg toolkit
-
- a. Go to http://developer.nvidia.com, the developer section and
- download the cg toolkit, version 1.5, and install it. The path
- where you choose to install Cg is referred to by the
- <Cg install location> tag in the steps below.
-
- b. During the installation, if the integrate with visual studio
- option is selected, the header files will be automatically found.
- Otherwise, copy the directory <Cg install location>\Cg\include\Cg
- to Deploy\include\Cg
-
- b. Copy the cg.dll and cgGL.dll from the <Cg install location>\Cg\bin
- into Deploy\bin\Release and Deploy\bin\Debug, or otherwise make
- them available (put them in system32, add to path, etc.)
-
- c. Copy the cg.lib and cgGL.lib from <Cg install location>\Cg\lib
- into Deploy\lib\Release and Deploy\lib\Debug
-
- 2. Make glut available. This can be done via several mechanisms.
- See step 4 below.
-
- 3. Make glew available. This can be done via several mechanisms.
- http://glew.sourceforge.net is the master site for this
- library. See step 4 below.
-
- 4. nVidia makes both glut and glew available in their SDK package,
- which is a fairly large download, but provides a wealth of other
- information on programming for the GPU, and is generally a useful
- package, so that is the path chosen for this set up.
-
- a. Go to http://developer.nvidia.com and download version 10 of the
- SDK and install it. It will prompt you to install the Cg toolkit,
- but this is not necessary as it was handled in step 1. The path
- where you choose to install the SDK is referred to by the
- <SDK install location> tag in the steps below.
-
- b. Make an nvidia folder at the top level, with an include and
- lib folder inside it. Inside the lib folder, make Debug and
- Release folders.
-
- c. Copy the <SDK install location>\external\include\GL directory into
- nvidia\include the GL and glh folders into nvidia\include.
-
- d. Copy the glew headers in <SDK install location>\common\GLEW\include\GL
- into nvidia\include\GL.
-
- e. Copy <SDK install location>\common\GLEW\lib\glew32.lib and
- <SDK install location>\external\lib\glut32.lib into Deploy\bin\Release.
-
- f. Copy bin\glut32.dll and bin\glew32.dll into Deploy\bin\Release.
-
- d. Build the Release configuration of the OpenEXR_Viewers.
-
- e. Build the Debug configuration if desired.
-
-At this point, the Deploy folder should be fully built out and ready
-to be used. Both exrdisplay and playexr are meant to be launched from
-the command line, as they originated as unix commands, so open a command
-prompt, cd to the Deploy\bin\Release folder and enjoy.

+// The purpose of this file is to make it possible to specify an
+// IEX_INTERNAL_NAMESPACE as a preprocessor definition and have all of the
+// Iex symbols defined within that namespace rather than the standard
+// Iex namespace. Those symbols are made available to client code through
+// the IEX_NAMESPACE in addition to the IEX_INTERNAL_NAMESPACE.
+//
+// To ensure source code compatibility, the IEX_NAMESPACE defaults to Iex
+// and then "using namespace IEX_INTERNAL_NAMESPACE;" brings all of the
+// declarations from the IEX_INTERNAL_NAMESPACE into the IEX_NAMESPACE. This
+// means that client code can continue to use syntax like Iex::BaseExc, but
+// at link time it will resolve to a mangled symbol based on the
+// IEX_INTERNAL_NAMESPACE.
+//
+// As an example, if one needed to build against a newer version of Iex and
+// have it run alongside an older version in the same application, it is now
+// possible to use an internal namespace to prevent collisions between the
+// older versions of Iex symbols and the newer ones. To do this, the
+// following could be defined at build time:
+//
+// IEX_INTERNAL_NAMESPACE = Iex_v2
+//
+// This means that declarations inside Iex headers look like this (after the
+// preprocessor has done its work):
+//
+// namespace Iex_v2 {
+// ...
+// class declarations
+// ...
+// }
+//
+// namespace Iex {
+// using namespace Iex_v2;

+// class DwaCompressor -- Store lossy RGB data by quantizing
+// DCT components.
+//
+// First, we try and figure out what compression strategy to take
+// based in channel name. For RGB channels, we want a lossy method
+// described below. But, if we have alpha, we should do something
+// different (and probably using RLE). If we have depth, or velocity,
+// or something else, just fall back to ZIP. The rules for deciding
+// which strategy to use are setup in initializeDefaultChannelRules().
+// When writing a file, the relevant rules needed to decode are written
+// into the start of the data block, making a self-contained file.
+// If initializeDefaultChannelRules() doesn't quite suite your naming
+// conventions, you can adjust the rules without breaking decoder
+// compatability.
+//
+// If we're going to lossy compress R, G, or B channels, it's easier
+// to toss bits in a more perceptual uniform space. One could argue
+// at length as to what constitutes perceptually uniform, expecially
+// when storing either scene/input/focal plane referred and output referred
+// data.
+//
+// We'll compromise. For values <= 1, we use a traditional power function
+// (without any of that straight-line business at the bottom). For values > 1,
+// we want something more like a log function, since power functions blow
+// up. At 1, we want a smooth blend between the functions. So, we use a
+// piecewise function that does just that - see dwaLookups.cpp for
+// a little more detail.
+//
+// Also, if we find that we have R, G, and B channels from the same layer,
+// we can get a bit more compression efficiency by transforming to a Y'CbCr
+// space. We use the 709 transform, but with Cb,Cr = 0 for an input of
+// (0, 0, 0), instead of the traditional Cb,Cr = .5. Shifting the zero point
+// makes no sense with large range data. Transforms are done to from
+// the perceptual space data, not the linear-light space data (R'G'B' ->
+// (Y'CbCr, not RGB -> YCbCr).
+//
+// Next, we forward DCT the data. This is done with a floating
+// point DCT, as we don't really have control over the src range. The
+// resulting values are dropped to half-float precision.
+//
+// Now, we need to quantize. Quantization departs from the usual way
+// of dividing and rounding. Instead, we start with some floating
+// point "base-error" value. From this, we can derive quantization
+// error for each DCT component. Take the standard JPEG quantization
+// tables and normalize them by the smallest value. Then, multiply
+// the normalized quant tables by our base-error value. This gives
+// a range of errors for each DCT component.
+//
+// For each DCT component, we want to find a quantized value that
+// is within +- the per-component error. Pick the quantized value
+// that has the fewest bits set in its' binary representation.
+// Brute-forcing the search would make for extremly inefficient
+// compression. Fortunatly, we can precompute a table to assist
+// with this search.
+//
+// For each 16-bit float value, there are at most 15 other values with
+// fewer bits set. We can precompute these values in a compact form, since
+// many source values have far fewer that 15 possible quantized values.
+// Now, instead of searching the entire range +- the component error,
+// we can just search at most 15 quantization candidates. The search can
+// be accelerated a bit more by sorting the candidates by the
+// number of bits set, in increasing order. Then, the search can stop
+// once a candidate is found w/i the per-component quantization
+// error range.
+//
+// The quantization strategy has the side-benefit that there is no
+// de-quantization step upon decode, so we don't bother recording
+// the quantization table.
+//
+// Ok. So we now have quantized values. Time for entropy coding. We
+// can use either static Huffman or zlib/DEFLATE. The static Huffman
+// is more efficient at compacting data, but can have a greater
+// overhead, especially for smaller tile/strip sizes.
+//
+// There is some additional fun, like ZIP compressing the DC components
+// instead of Huffman/zlib, which helps make things slightly smaller.
+//
+// Compression level is controlled by setting an int/float/double attribute
+// on the header named "dwaCompressionLevel". This is a thinly veiled name for
+// the "base-error" value mentioned above. The "base-error" is just
+// dwaCompressionLevel / 100000. The default value of 45.0 is generally
+// pretty good at generating "visually lossless" values at reasonable
+// data rates. Setting dwaCompressionLevel to 0 should result in no additional
+// quantization at the quantization stage (though there may be
+// quantization in practice at the CSC/DCT steps). But if you really
+// want lossless compression, there are pleanty of other choices
+// of compressors ;)
+//
+// When dealing with FLOAT source buffers, we first quantize the source
+// to HALF and continue down as we would for HALF source.

+// and 'offset') which drive the decoding. To cut down on the
+// linear scanning of these tables, you can add a small table
+// to directly look up short codes (as you might in a traditional
+// lookup-table driven decoder).

+// The purpose of this file is to have all of the Imath symbols defined within
+// the OPENEXR_IMF_INTERNAL_NAMESPACE namespace rather than the standard Imath
+// namespace. Those symbols are made available to client code through the
+// OPENEXR_IMF_NAMESPACE in addition to the OPENEXR_IMF_INTERNAL_NAMESPACE.
+//
+// To ensure source code compatibility, the OPENEXR_IMF_NAMESPACE defaults to
+// Imath and then "using namespace OPENEXR_IMF_INTERNAL_NAMESPACE;" brings all
+// of the declarations from the OPENEXR_IMF_INTERNAL_NAMESPACE into the
+// OPENEXR_IMF_NAMESPACE.
+// This means that client code can continue to use syntax like
+// Imf::Header, but at link time it will resolve to a
+// mangled symbol based on the OPENEXR_IMF_INTERNAL_NAMESPACE.
+//
+// As an example, if one needed to build against a newer version of Imath and
+// have it run alongside an older version in the same application, it is now
+// possible to use an internal namespace to prevent collisions between the
+// older versions of Imath symbols and the newer ones. To do this, the
+// following could be defined at build time:
+//
+// OPENEXR_IMF_INTERNAL_NAMESPACE = Imf_v2
+//
+// This means that declarations inside Imath headers look like this (after
+// the preprocessor has done its work):
+//
+// namespace Imf_v2 {
+// ...
+// class declarations
+// ...
+// }
+//
+// namespace Imf {
+// using namespace IMF_NAMESPACE_v2;

+// The purpose of this file is to make it possible to specify an
+// ILMTHREAD_INTERNAL_NAMESPACE as a preprocessor definition and have all of
+// the IlmThread symbols defined within that namespace rather than the
+// standard IlmThread namespace. Those symbols are made available to client
+// code through the ILMTHREAD_NAMESPACE in addition to the
+// ILMTHREAD_INTERNAL_NAMESPACE.
+//
+// To ensure source code compatibility, the ILMTHREAD_NAMESPACE defaults to
+// IlmThread and then "using namespace ILMTHREAD_INTERNAL_NAMESPACE;" brings
+// all of the declarations from the ILMTHREAD_INTERNAL_NAMESPACE into the
+// ILMTHREAD_NAMESPACE. This means that client code can continue to use
+// syntax like IlmThread::Thread, but at link time it will resolve to a
+// mangled symbol based on the ILMTHREAD_INTERNAL_NAMESPACE.
+//
+// As an example, if one needed to build against a newer version of IlmThread
+// and have it run alongside an older version in the same application, it is
+// now possible to use an internal namespace to prevent collisions between
+// the older versions of IlmThread symbols and the newer ones. To do this,
+// the following could be defined at build time:
+//
+// ILMTHREAD_INTERNAL_NAMESPACE = IlmThread_v2
+//
+// This means that declarations inside IlmThread headers look like this
+// (after the preprocessor has done its work):
+//
+// namespace IlmThread_v2 {
+// ...
+// class declarations
+// ...
+// }
+//
+// namespace IlmThread {
+// using namespace IlmThread_v2;
+// }

+//
+// The purpose of this file is to make it possible to specify an
+// IMATH_INTERNAL_NAMESPACE as a preprocessor definition and have all of the
+// Imath symbols defined within that namespace rather than the standard
+// Imath namespace. Those symbols are made available to client code through
+// the IMATH_NAMESPACE in addition to the IMATH_INTERNAL_NAMESPACE.
+//
+// To ensure source code compatibility, the IMATH_NAMESPACE defaults to Imath
+// and then "using namespace IMATH_INTERNAL_NAMESPACE;" brings all of the
+// declarations from the IMATH_INTERNAL_NAMESPACE into the IMATH_NAMESPACE.
+// This means that client code can continue to use syntax like Imath::V3f,
+// but at link time it will resolve to a mangled symbol based on the
+// IMATH_INTERNAL_NAMESPACE.
+//
+// As an example, if one needed to build against a newer version of Imath and
+// have it run alongside an older version in the same application, it is now
+// possible to use an internal namespace to prevent collisions between the
+// older versions of Imath symbols and the newer ones. To do this, the
+// following could be defined at build time:
+//
+// IMATH_INTERNAL_NAMESPACE = Imath_v2
+//
+// This means that declarations inside Imath headers look like this (after
+// the preprocessor has done its work):
+//
+// namespace Imath_v2 {
+// ...
+// class declarations
+// ...
+// }
+//
+// namespace Imath {
+// using namespace Imath_v2;
+// }
+//

+// for the configure time options.

+ * LFPQUANT - Lossless Fast Pseudo-Quantization Algorithm
+ *
+ * The Lossless Fast Pseudo-Quantization algorithm is no real quantization
+ * algorithm, since it makes no attempt to create a palette, that is suitable
+ * for all colors of the 24-bit source image. However, it provides very fast
+ * conversions from 24-bit to 8-bit images, if the number of distinct colors
+ * in the source image is not greater than the desired palette size. If the
+ * number of colors in the source image is exceeded, the Quantize method of
+ * this implementation stops the process and returns NULL.
+ *
+ * This implementation uses a very fast hash map implementation to collect
+ * the source image's colors. It turned out that a customized implementation
+ * of a hash table with open addressing (using linear probing) provides the
+ * best performance. The hash table has 512 entries, which prevents the load
+ * factor to exceed 0.5 as we have 256 entries at most. Each entry consumes
+ * 64 bits, so the whole hash table takes 4KB of memory.
+ *
+ * For large images, the LFPQuantizer is typically up to three times faster
+ * than the WuQuantizer.

- Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
- x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
-
- Polynomials over GF(2) are represented in binary, one bit per coefficient,
- with the lowest powers in the most significant bit. Then adding polynomials
- is just exclusive-or, and multiplying a polynomial by x is a right shift by
- one. If we call the above polynomial p, and represent a byte as the
- polynomial q, also with the lowest power in the most significant bit (so the
- byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
- where a mod b means the remainder after dividing a by b.
-
- This calculation is done using the shift-register method of multiplying and
- taking the remainder. The register is initialized to zero, and for each
- incoming bit, x^32 is added mod p to the register if the bit is a one (where
- x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
- x (which is shifting right by one and adding x^32 mod p if the bit shifted
- out is a one). We start with the highest power (least significant bit) of
- q and repeat for all eight bits of q.
-
- The first table is simply the CRC of all possible eight bit values. This is
- all the information needed to generate CRCs on data a byte at a time for all
- combinations of CRC register values and incoming bytes. The remaining tables
- allow for word-at-a-time CRC calculation for both big-endian and little-
- endian machines, where a word is four bytes.

+ Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:

+
+ Polynomials over GF(2) are represented in binary, one bit per coefficient,
+ with the lowest powers in the most significant bit. Then adding polynomials
+ is just exclusive-or, and multiplying a polynomial by x is a right shift by
+ one. If we call the above polynomial p, and represent a byte as the
+ polynomial q, also with the lowest power in the most significant bit (so the
+ byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
+ where a mod b means the remainder after dividing a by b.
+
+ This calculation is done using the shift-register method of multiplying and
+ taking the remainder. The register is initialized to zero, and for each
+ incoming bit, x^32 is added mod p to the register if the bit is a one (where
+ x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
+ x (which is shifting right by one and adding x^32 mod p if the bit shifted
+ out is a one). We start with the highest power (least significant bit) of
+ q and repeat for all eight bits of q.
+
+ The first table is simply the CRC of all possible eight bit values. This is
+ all the information needed to generate CRCs on data a byte at a time for all
+ combinations of CRC register values and incoming bytes. The remaining tables
+ allow for word-at-a-time CRC calculation for both big-endian and little-
+ endian machines, where a word is four bytes.

-/*
- * ALGORITHM
- *
- * The "deflation" process depends on being able to identify portions
- * of the input text which are identical to earlier input (within a
- * sliding window trailing behind the input currently being processed).
- *
- * The most straightforward technique turns out to be the fastest for
- * most input files: try all possible matches and select the longest.
- * The key feature of this algorithm is that insertions into the string
- * dictionary are very simple and thus fast, and deletions are avoided
- * completely. Insertions are performed at each input character, whereas
- * string matches are performed only when the previous match ends. So it
- * is preferable to spend more time in matches to allow very fast string
- * insertions and avoid deletions. The matching algorithm for small
- * strings is inspired from that of Rabin & Karp. A brute force approach
- * is used to find longer strings when a small match has been found.
- * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
- * (by Leonid Broukhis).
- * A previous version of this file used a more sophisticated algorithm
- * (by Fiala and Greene) which is guaranteed to run in linear amortized
- * time, but has a larger average cost, uses more memory and is patented.
- * However the F&G algorithm may be faster for some highly redundant
- * files if the parameter max_chain_length (described below) is too large.
- *
- * ACKNOWLEDGEMENTS
- *
- * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
- * I found it in 'freeze' written by Leonid Broukhis.
- * Thanks to many people for bug reports and testing.

+/*
+ * ALGORITHM
+ *
+ * The "deflation" process depends on being able to identify portions
+ * of the input text which are identical to earlier input (within a
+ * sliding window trailing behind the input currently being processed).
+ *
+ * The most straightforward technique turns out to be the fastest for
+ * most input files: try all possible matches and select the longest.
+ * The key feature of this algorithm is that insertions into the string
+ * dictionary are very simple and thus fast, and deletions are avoided
+ * completely. Insertions are performed at each input character, whereas
+ * string matches are performed only when the previous match ends. So it
+ * is preferable to spend more time in matches to allow very fast string
+ * insertions and avoid deletions. The matching algorithm for small
+ * strings is inspired from that of Rabin & Karp. A brute force approach
+ * is used to find longer strings when a small match has been found.
+ * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
+ * (by Leonid Broukhis).
+ * A previous version of this file used a more sophisticated algorithm
+ * (by Fiala and Greene) which is guaranteed to run in linear amortized
+ * time, but has a larger average cost, uses more memory and is patented.
+ * However the F&G algorithm may be faster for some highly redundant
+ * files if the parameter max_chain_length (described below) is too large.
+ *
+ * ACKNOWLEDGEMENTS
+ *
+ * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
+ * I found it in 'freeze' written by Leonid Broukhis.
+ * Thanks to many people for bug reports and testing.

- * ALGORITHM
- *
- * The "deflation" process uses several Huffman trees. The more
- * common source values are represented by shorter bit sequences.
- *
- * Each code tree is stored in a compressed form which is itself
- * a Huffman encoding of the lengths of all the code strings (in
- * ascending order by source values). The actual code strings are
- * reconstructed from the lengths in the inflate process, as described
- * in the deflate specification.

+ *
+ * Each code tree is stored in a compressed form which is itself

+This awk script is used to generate a VB6 module with all the VB6 declaration needed to call FreeImage functions.
+
+How to use this script
+----------------------
+Under Linux / Unix, just execute the following commands :
+
+chmod 755 genbas.sh
+./genbas.sh
+
+
+This will generate a file named modFreeImage.bas that you can include in your VB6 project in order to have access to all FreeImage functions.

'// ==========================================================
Option Explicit
-'--------------------------------------------------------------------------------
-' General notes on implementation and design
-'--------------------------------------------------------------------------------
-
-' General:
-
-' Most of the pointer type parameters used in the FreeImage API are actually
-' declared as Long in VB. That is also true for return values. 'Out' parameters
-' are declared ByRef, so they can receive the provided address of the pointer.
-' 'In' parameters are declared ByVal since in VB the Long variable is not a
-' pointer type but contains the address of the pointer.
-
-
-' Functions returning a special type:
-
-' Some of the following external function declarations of the FreeImage 3 functions
-' are declared Private. Additionally the token 'Int' is appended to the VB function
-' name, what means 'Internal' to avoid naming confusion. All of these return a value
-' of a certain type that can't be used with a declared function in VB directly but
-' would need the function to be declared in a type library. Since this wrapper module
-' should not depend on a compile time type library, these functions require some extra
-' work to be done and also a VB wrapper function to make them look like the C/C++
-' function.
-
-
-' Functions returning Strings:
-
-' Some of the declared FreeImage functions are defined as 'const char *' in C/C++
-' and so actually return a string pointer. Without using a type library for declaring
-' these functions, in VB it is impossible to declare these functions to return a
-' VB String type. So each of these functions is wrapped by a VB implemented function
-' named correctly according to the FreeImage API, actually returning a 'real' VB String.
-
-
-' Functions returning Booleans:
-
-' A Boolean is a numeric 32 bit value in both C/C++ and VB. In C/C++ TRUE is defined
-' as 1 whereas in VB True is -1 (all bits set). When a function is declared as 'Boolean'
-' in VB, the return value (all 32 bits) of the called function is just used "as is" and
-' maybe assigned to a VB boolean variable. A Boolean in VB is 'False' when the numeric
-' value is NULL (0) and 'True' in any other case. So, at a first glance, everything
-' would be great since both numeric values -1 (VB True) and 1 (C/C++ TRUE) are actually
-' 'True' in VB.
-' But, if you have a VB variable (or a function returning a Boolean) with just some bits
-' set and use the VB 'Not' operator, the result is not what you would expect. In this
-' case, if bTest is True, (Not bTest) is also True. The 'Not' operator just toggles all
-' bits by XOR-ing the value with -1. So, the result is not so surprisingly any more:
-' The C/C++ TRUE value is 0...0001. When all bits are XORed with 1, the result is
-' 1...1110 what is also not NULL (0) so this is still 'True' in VB.
-' The resolution is to convert these return values into real VB Booleans in a wrapper
-' function, one for each declared FreeImage function. Therefore each C/C++ BOOL
-' function is declared Private as xxxInt(...). A Public Boolean wrapper function
-' xxx(...) returns a real Boolean with 'xxx = (xxxInt(...) = 1)'.
-
-
-' Extended and derived functions:
-
-' Some of the functions are additionally provided in an extended, call it a more VB
-' friendly version, named '...Ex'. For example look at the 'FreeImage_GetPaletteEx'
-' function. Most of them are dealing with arrays and so actually return a VB style
-' array of correct type.
-
-' The wrapper also includes some derived functions that should make life easier for
-' not only a VB programmer.
-
-' Better VB interoperability is given by offering conversion between DIBs and
-' VB Picture objects. See the FreeImage_CreateFromOlePicture and
-' FreeImage_GetOlePicture functions.
-
-' Both known VB functions LoadPicture() and SavePicture() are provided in extended
-' versions calles LoadPictureEx() and SavePictureEx() offering the FreeImage 3�s
-' image file types.
-
-' The FreeImage 3 error handling is provided in VB after calling the VB specific
-' function FreeImage_InitErrorHandler()
-
-
-' Enumerations:
-
-' All of the enumaration members are additionally 'declared' as constants in a
-' conditional compiler directive '#If...#Then' block that is actually unreachable.
-' For example see:
-'
-' Public Enum FREE_IMAGE_QUANTIZE
-' FIQ_WUQUANT = 0 ' Xiaolin Wu color quantization algorithm
-' FIQ_NNQUANT = 1 ' NeuQuant neural-net quantization algorithm by Anthony Dekker
-' End Enum
-' #If False Then
-' Const FIQ_WUQUANT = 0
-' Const FIQ_NNQUANT = 1
-' #End If
-'
-' Since this module is supposed to be used directly in VB projects rather than in
-' compiled form (mybe through an ActiveX-DLL), this is for tweaking some ugly VB
-' behaviour regarding enumerations. Enum members are automatically adjusted in case
-' by the VB IDE whenever you type these members in wrong case. Since these are also
-' constants now, they are no longer adjusted to wrong case but always corrected
-' according to the definition of the constant. As the expression '#If False Then'
-' actually never comes true, these constants are not really defined either when running
-' in the VB IDE nor in compiled form.
-
-
-'--------------------------------------------------------------------------------
-' ToDo and known issues (unordered and with no priority)
-'--------------------------------------------------------------------------------
-
-' ToDo: more inline documentation for mask image creation and icon functions
-' needed
