Thanks Even for the quick reply. I have an older build of GDAL with poppler
that works rendering the page I provided, but I am attempting to perform a full
custom build of poppler with static builds of all third-party libraries. Now,
I cannot view the logo and just wondering if someone could provide a little
insight how Adobe PDF stores the Logo image an in XObject. Is the image stored
as a standard uncompressed RGB image, zipped image, png image? I just need a
little information on where to search within the Hex data of the PDF file to
debug my problem. This questions probably should fall under the poppler
project. I will do that and I just chose to use GDAL as I am using GDAL API
interface for PDF read/write. Bob

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/
