Re: [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/

Re: [gdal-dev] S57 SDK in .NET developer

[Dmitry Baryshnikov]

Hi, Thang,

What is the different between  S57 SDK for .NET and GDAL S57 driver with 
CSharp bindings?

There is the sources and API?

Best regards,
Dmitry

Re: [gdal-dev] How to deal with IIP image via WMS minidriver?

[Even Rouault]

Carlo,

I've just committed in GDAL trunk a IIP mini driver. Requires a IIP server
that supports the JTL extension (which was the case for the 2 online services I 
tested).
Online doc at http://www.gdal.org/frmt_wms.html will be refreshed in a few 
hours.

Re: [gdal-dev] PDF Image Rendering issues with Poppler

[Robert Zermeno]

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
