[Pkg-cups-devel] Bug#348061: cupsys: pdftops conversion fails on transparency in PDF-files

[Peter Griffin]

Package: cupsys
Version: 1.1.23-12
Severity: important

When printing PDF files with transparent object, the transparency is
broken due to the pdftops conversion in the cups printing process.

To add some detail, I am printing from a Mac OS X client to a Debian
Cups-server via the automatic printer detection. The PDF File seems to
be passed to the cups-server, which converts the PDF-file to PS by
utilizing xdpf-utils's pdftops. Although, xdpf is able to process
transparency since version 3.01 and does display the pdf file
correctly, pdftops fails.

I wasn't quite sure to where to report this bug (xpf-utils?). But, I
decided to send it to cupsys because the error affects my cups
printserver.

By the way, pdf2ps and acroread -toPostScript process correct PS-files
retaining the transparency.
