Description Marcos H. Woehrmann 2009-10-29 15:41:24 UTC 
The following files are rendered with a large portions of the page black when
converted to pxlcolor and then to ppmraw (see attached):

CATX2063.pdf (page 1)
CATX0988.pdf (page 2 and 3)

Command lines used for testing:

  gshead -sDEVICE=pxlcolor -r600 -o test1.pxl ./$1
  pclhead -sDEVICE=ppmraw -r600 -sOutputFile=viapxl.ppm -dNOPAUSE ./test1.pxl

  gshead -sDEVICE=ppmraw -r600 -o direct.ppm ./$1

I'm testing with r10243 for both GhostPCL and Ghostscript.

The files may be found in the private repository in
/tests_private/pdf/PDFIA1.7_SUBSET/

Comment 2 Hin-Tak Leung 2009-11-07 15:13:05 UTC 
This is another unfortunate effect of r8733 (fix attempt to 688372) being wrong.
Reverting that shows correct output.

The correct fix to bug 688372 is attached there.
Comment 3 Hin-Tak Leung 2009-11-23 18:18:01 UTC 
r10303 'reverting r8733, which was a faulty fix to bug 688372' fixes this.
