[gdal-dev] PDF Image Rendering issues with Poppler

[Even Rouault]

Robert,

Works fine for me with poppler 0.35.0 on Linux and with GDAL trunk.

One key information you didn't mention is your GDAL version. If it is 1.11.2 
or older, poppler >= 0.31.0 isn't supported.
See https://trac.osgeo.org/gdal/ticket/6118

You can also test with the builds / SDKs at http://www.gisinternals.com/
