Hatching pattern example
In the attached file, all four rectangles should be painted with a Pattern with the same diagonal lines. Using poppler-glib-demo to render this file, the rectangle in the bottom left does not show any lines. The same thing occurs in evince (as expected, I guess, since it's using poppler-glib as well.)
If I use okular (which uses poppler-qt, if I'm not mistaken), then the bottom-left rectangle shows the lines.
If I use pdftocairo, the lines do not appear in any of the outputs.
If I use pdftops or pdftoppm and view the result in evince/eog, the lines *do* appear.
Additionally, I can round-trip through ghostscript with `pdftops hatching.pdf - | ps2pdf - test.pdf` and _that_ file does work.
Method | Works?
poppler-glib-demo | No
evince | No
okular | Yes
pdftocairo -png | No
pdftops + evince | Yes
pdftoppm + eog | Yes
pdftops + ps2pdf | Yes
This fails with both Fedora's poppler-0.41.0-3.fc24.x86_64 and the poppler-0.48 tag from git that I compiled myself.
The file was created with Matplotlib and if there's some way to easily tweak the file to get it working in all cases, I can make that adjustment.
