Dear Albert,
thank you for your time to perform the regression tests!
I have fixed the bug; it was a data type problem.
Attached you find the fixed version.
The file
bugfix_shadingtype4567_incremental.patch
is relative to the version you used for the regression tests.
The file
bugfix_shadingtype4567_poppler0.14.patch
is relative to poppler-0.14.0-3-gb2427d0 .
Thank you for considering my contributions.
I've ran the regression test with the Splash outputdev and all looks ok,
will have to run it over the cairo and ps outputdevs before committing,
though it'll take a while since next week i'm going to be away on
holidays.
Bad news, this patch produces a regression in pdftops when running over
the attached file, that is, the unpatched version creates a ps file that
is valid (gs will open it) and the patched version creates a ps file
that "crashes" gs.
Do you think you can have a look?
Albert
Dear Albert,
I am having difficulties to reproduce the problem. Here is what I did:
1. try to view bug157704.pdf with the standard gs
--> crash (see below)
2. call pdftops (using system's version of libpoppler) and open gs on
the result
--> works without errors (see below)
3. call pdftops using the patched libpoppler and open gs on the result
--> works without errors
4. call pdftops of poppler git version of 0.14 without my patch (I have
not yet pulled the new version) and open gs on the result
--> works without errors
Do you have more detailed information about the crash? I fear I am
unable to do anything here...
Wops, works for me now too, i must have done something weird, sorry :-/
I'll start the regression test again.
Albert
Ok, thanks for the notice!
Best regards
Christian

Hello Albert,
Hi
I've managed to fix a bug in the Shading Type 6/7 (Coons& cubic
tensor patches) implementation.
The bugfix is small and stable (in my eyes); the poppler-0.14 branch
doesn't implement support for parameterized patch shadings. I
modified the existing implementation accordingly with relatively few
changes.
Attached you find the patch file and the updated test.pdf to see the
improvement.
The file type4567patch.... also includes the patch of my previous
mail (they only share the same refinement threshold).
The patch should work relative to poppler-0.14.0-3-gb2427d0 .
This patch causes a regression in the attached pdf (the blue area
disappears)
Albert
Best regards
Christian
