Starting with r11902 page 22 of 09-30.PS shows a regression when rendered to a pkmraw file (see the attached file for the differences, r11902 output is on the left, r11901 is in the middle, and the difference is on the right).  With r11901 or earlier the pkmraw output matches the pbm/pgm/ppm output.

The command line I'm using for testing:

  bin/gs -sDEVICE=pkmraw -o test.ppm ./09-40.PS
Comment 1 Marcos H. Woehrmann 2010-11-27 07:31:11 UTC
The r11902 change also introduced a regression on page 1 of 12-07A.PS.  In this case with all output formats (pbmraw/pgmraw/etc).  I sent the file to a PostScript printer for comparison and the printout matched the r11901 output.

See the attached file for the difference.

The file comparefiles/119-47.ps also exhibits a regression with r11902.
Comment 6 Marcos H. Woehrmann 2010-11-29 07:07:38 UTC
The regression with 119-47.ps only occurs with pkmraw output.  Here is a sample command line:

./bin/gs -sDEVICE=pkmraw -o test.pkm -r72 -dNOOUTERSAVE -dJOBSERVER -c false 0 startjob pop -f - < ./119-47.ps

Several of these have been fixed with

I am having trouble running 

tests_private__comparefiles__119-47.ps.pkmraw.72.0.page_1.png 

on windows.  It never ends.
