            Bug ID: 104232
           Summary: Fails to render large PNG in PDF (leaves blank space)
           Product: poppler
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: cairo backend
          Assignee: poppler-bugs at lists.freedesktop.org

Created attachment 136124
  --> https://bugs.freedesktop.org/attachment.cgi?id=136124&action=edit
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
