           Summary: Significant differences with pkmraw vs ppmraw with
                    icc_work code
           Product: Ghostscript
           Version: HEAD
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P4
         Component: Color

Starting with r11306 there are significant differences with the output from
Ghostscript when converting Bug690835.pdf (found in the tests_private
repository in the comparefiles directory) to pkmraw vs. ppmraw.  These
differences are not present when using r11305 nor when opening the file with
Photoshop CS5.

See the attached screenshot.png for what I mean by "significant differences".

The command lines I'm using for testing:

  bin/gs -sDEVICE=pkmraw -o test.pkm ./Bug690835.pdf
  bin/gs -sDEVICE=ppmraw -o test.ppm ./Bug690835.pdf
