PDFsharp & MigraDoc Foundation

First, I'm new to PDFsharp, so sorry is this is in the wrong place. I did a broad search and didn't find anthing on this topic. I'm running the latest version of the code, downloaded 02Mar2013.

[Issue]: I have a PDFv1.3 file with embedded JPEG images. GetName() is throwing when it tries to parse /Filter key.(PDF header below) Any help would be greatly apprciated!

throw new InvalidCastException("GetName: Object is not a name.");

%PDF-1.3
% âãÏÓ
3 0 obj
<< /Type /XObject
/Subtype /Image
/Width 2144
/Height 2848
/BitsPerComponent 8
/Length 629552
/ColorSpace /DeviceRGB
/Filter [/FlateDecode /DCTDecode]
>>
stream

A refined search turned up this thread: viewtopic.php?f=2&t=1053&p=2814&hilit=%2FFilter+%5B%2FFlateDecode+%2FDCTDecode%5D#p2814

I guess the answer is: "Not supported...." Back to square one. It also apears that GetImage() doesn't handle /FlateDecode, so not sure what I'm going to do......

The answer is "left as an exercise to the reader". The sample is only meant to get you started.

With "/Filter [/FlateDecode /DCTDecode]" you only have to call the decoder for "/FlateDecode" to get the JPEG file.

Thanks Thomas.... We always want life to be simple. With the other thread you provided, and a bit of work on my part, I was able to isolate the internally compressed jpeg stream, decompress it, and save the image.
