Package: octave2.9-forge
Version: 2006.07.09+dfsg1-5
Severity: normal
Hello,
octave2.9:1> imread("darkimage.tif");
warning: implicit conversion from matrix to string
error: imread: invalid image depth
error: evaluating if command near line 76, column 5
error: called from `imread' in file
`/usr/share/octave/site/api-v22/m/octave2.9- forge/image/imread.m'
looking at line 72 of imread.m:
depth = re_grab("Red: ([[:digit:]]{1,2})", ident);
this results in "" with my file.
If you need the file for testing purposes please let me know.
