Description Marcos H. Woehrmann 2010-07-08 05:44:51 UTC

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

Have this narrowed down to c-list transparency issue

I have this narrowed down to a incorrect setting of the color mapping procedures in the graphics state during pdf14 color space changes.  Should have a fix soon.

Fixed with rev 11504
