Subject [jira] Commented: (PDFBOX-483) rendering issues during clipping (W/W*-operator)

Daniel Wilson commented on PDFBOX-483:
--------------------------------------

Congratulations, Andreas!  This one was not easy!

I have updated several of the test cases with the output from this version. Flyer2 looks a
lot better and several others list changes that I can't see ... so I'm updating to the output
from the new code.

My test files, however, are not all looking right.

HotRodCMYK, for example ... the new output is much darker in the letters ... the clipped part
where the bitmask is. Likewise ArchiveRGB.  The latter shows clearly a diagonal streaking
of the pattern, something that HotRodCMYK hints at but does not show clearly.

There are some others I have that show the same thing that I've not received approval to release.
 But those 2 I've released do show the problem.

Given the chance, I'll dig into this, being mindful of the other test cases -- like Flyer2.
 But if something comes to your mind on it, I'd appreciate the suggestions!

> As I already stated in this thread [1], there are some rendering issues after adding
support for the W/W*-operators (clipping).
> E.g. the rendering of Flyer2.pdf from PDFBOX-358 and the doc attached to PDFBOX-478 is
getting worse if clipping is activated.
