------------------------------------------------------------------
I have set a maximum surface of 25000000 for a pattern image, this is 5000 x
5000 and dpi isn't even counted.
Initially, this check activated only with your file and another (
https://bugs.ghostscript.com/show_bug.cgi?id=693134 ) that doesn't have an
issue here yet. The values are arbitrary and there might still be trouble with
a large dpi. Your file renders fine up to 400% (= 288dpi), but not at 1000%
(720dpi).
I also tried to limit the sizes to the page sizes, but that didn't work with
several other files; I suspect that at a later time, the calculated large
patterns get resized so their full surface is needed.
I have also decided to remove the code that sets big (> 32767) XStep and YStep
values to 0. Rendering with the modified code shows improvements:
- PDFBOX-3447-XStep99999.pdf: the pattern repetition at the top (didn't notice
before, it is on top of the blue part) is gone
- PDFJS-6496-XStep99999.pdf: the pattern repetition at the right (didn't notice
before, the dotted line was double) is gone
- PDFJS-7731-XStep99999.pdf: the pattern repetition at the bottom (easy to see)
is gone
An even better solution for the future would be to paint patterns with big
sizes only once, i.e. not use TexturePaint.
