PDF including PNG image which fails to render.
The attached PDF includes a 1492x1286 PNG image (the right half of Figure 5 on page 8) which fails to render when using pdftocairo -png (the space it should occupy is simply blank). It shows up fine in Acrobat Reader (I originally encountered this bug in Evince).
I have an identical document which includes a PDF file at that point instead of a PNG (I say "includes" but that's at the XeTeX source level, so presumably the contents of that PDF get transparently added to the complied output?). The version using the PDF-include works fine, the problem is that it takes a few seconds to load in Evince and quite a while in Acrobat Reader because the image is a graph with ~100,000 points (hence wanting to rasterize it).
FWIW I'm on Arch Linux 4.14.3-1 using Poppler 0.61.1-1
I should mention from cursory research this is possibly related to:
but the example documents posted in those bugs seem to work okay for me. The second bug example perhaps had some issues, but included error messages on the console (from Evince) as follows:
*** BUG ***
In pixman_region32_init_rect: Invalid rectangle passed
Set a breakpoint on '_pixman_log_error' to debug
These did not occur when viewing the document I uploaded.
