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

  • The PDF file produced by the pdfwrite device renders differently with Ghostscript and is (subtly) different when exported to TIFF from Acrobat. There appears to be a bug for this one already: https://bugs.ghostscript.com/show_bug.cgi?id=702033 However there's no progress in 6 weeks. In addition I see differences when rendering the PDF file in Acrobat and with earlier versions of Ghostscript.

  • The PDF file produced by the pdfwrite device after the filll+stroke commit renders the blue lines considerably darker than the PDF file produced before that commit. Acrobat displays both PDF files apparently identically.

  • Gray gradients turn blue with the psdrgb device since the fill+stroke commit. There are many examples, this is a reasonably simple example
  • gswin64c -sDEVICE=psdrgb -o out%d.psd Layout.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

https://ghostscript.com/~regression/release__gs/compare1306.html#23085 - NOT A BUG?

The appearance of a couple of green crosses matches what Acrobat 9 Pro does for me when the Output Preview is used.

https://ghostscript.com/~regression/release__gs/compare1306.html#23086 - FIXED

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. This was commit http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=b7d32c453538bee41c34f8a77a3feb1dcc0ce759

Other regressions

https://ghostscript.com/~regression/release__gs/compare1146.html#19945 - FIXED

The 'buttons' have white horizontal stripes when rendered. Fixed in https://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=6ace930c11984e64aded98f1ff8db47104424354
