[poppler] Help with pdftohtml background image resolution

[ChunWei Ho]

I also tried poppler-0.5.91 (earliest that builds for me), but that
has the same issue. I tried looking into/diffing the code but not
seeing an obvious fix/issue there.

I've logged a bug at https://bugs.freedesktop.org/show_bug.cgi?id=29551

Its probably not affecting too many users, but I appreciate if it can
be investigated soon as it would be great to be able to deploy
poppler-utils for our purposes.

Thanks.
