[Openicc] [noreply at sourceforge.net: [ gimp-print-Bugs-3299815 ] CUPS PPD broken on Linux]

[Robert Krawitz]

OK, it looks like we finally have to find a real solution for this
problem.  At the very least, how do we determine, on any given system,
what profiles we need to embed in the PPD file and where to find them?

Summary: CUPS PPD broken on Linux

Initial Comment:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=625925

genppd.c hardcodes paths to ICC profiles.  These are Mac-specific, and are not present on Linux systems.  With a recent version of CUPS, which makes use of ICC profiles, printing breaksdue to the profiles being invalid.  This has been broken since 5.2.1, but not noticed because up until now CUPS was not making use of the information on Linux systems.  This block of code should be made conditional so that this information is only put into the PPD on Mac builds, or is only used on Mac versions of CUPS if you can make it conditional inside the PPD.

   /* Macintosh color management */
  gzputs(fp, "*cupsICCProfile Gray../Grayscale: \"/System/Library/ColorSync/Profiles/sRGB Profile.icc\"\n");
  gzputs(fp, "*cupsICCProfile RGB../Color:      \"/System/Library/ColorSync/Profiles/sRGB Profile.icc\"\n");
  gzputs(fp, "*cupsICCProfile CMYK../Color:     \"/System/Library/ColorSync/Profiles/Generic CMYK Profile.icc\"\n");
  gzputs(fp, "*APSupportsCustomColorMatching: true\n");
  gzputs(fp, "*APDefaultCustomColorMatchingProfile: sRGB\n");
  gzputs(fp, "*APCustomColorMatchingProfile: sRGB\n");

Roger
