Hi,

I have an issue with a PDF that I can open in Adobe and Foxit Reader without any issues.
It looks like it uses an encode format that PDFSharp does not support.

PDFSharp is great but if I can't process this file then it will be useless to me :cry:

I can email the PDF in question if needed.

Thanks,

Lourens

PdfSharp supports FlateDecode. It's usage is as follows:

Code:

byte[] input = new FlateDecode().Decode(dictionary.Stream.Value);

Make sure that you check to see that you dictionary stream has been encoded using FlateDecode:

Code:

if(dictionary.Elements.GetString("/Filter") == "/FlateDecode") { ... }

The API reference helped me a lot with the encoding, you can download it here. http://pdfsharp.codeplex.com/downloads/get/96265
