regressions introduced by Fill+stroke commit

https://ghostscript.com/~regression/release__gs/compare1242.html#21691 - FIXED

  • Third image down, the dark blue stroke bounding the mid blue underline has significantly reduced thickness. Seems to work correctly with clist, badly without.
  • -sOutputFile='tests_private__pdf__sumatra__893_-_details_missing_in_tape_reel.pdf.ppmraw' -dMaxBitmap=400000000 -sDEVICE=ppmraw -r300 -Z: -sDEFAULTPAPERSIZE=letter -dNOPAUSE -dBATCH -K2000000 -dClusterJob -dJOBSERVER ../tests_private/pdf/sumatra/893_-_details_missing_in_tape_reel.pdf

We additionally have the bug reported by Serendipity (probably the only customer even aware there is a Release Candidate, let alone tested it) https://bugs.ghostscript.com/show_bug.cgi?id=702128 - FIXED with https://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=646007af056447fefd61eabfcdae85bfd6017d24

Overprint regressions


  • Looking at this I see that there is a bug, but it appears (to me) to be a long-standing bug in pdfwrite, which is not tracking overprint mode properly. I have a tentative fix, but this is not a regression so I don't think we should hold anything up for this.

https://ghostscript.com/~regression/release__gs/compare1307.html#23090 - FIXED

In all three cases there are crosses (intended to indicate whether overprint is correctly processed) which appear or disappear. It seems likely the disappearing crosses are in fact progressions, but the ones which appear are probably regressions and I cannot make the red cross on a white background appear in Acrobat no matter what combination of profiles and overprint simulation I use, this appears to be quite incorrect.

Chris points to this commit http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=b7d32c453538bee41c34f8a77a3feb1dcc0ce759 and notes that we accepted problems at the time because there were more progressions than regressions.
