Hi,

As part of a project I am involved in I am testing the current implementation with PDF's created in Adobe v9. At the point where we apply an overlay to the original PDF an exception occurs.

[PdfReaderException: Cannot handle iref streams. The current implementation of PDFsharp cannot handle this PDF feature introduced with Acrobat 6.]

Earlier versions seem OK. I'm using the same word document to create the PDF.

We are using version 1.0.898.

Can this version of PDFsharp handle v9 Adobe output?

Thanks

Has no one experienced issues with Acrobat v9 output?

I'm surprised that there hasn't even been a reply about this... surely someone must know????

ive run into this problem. I'm pretty sure there are other older threads on this topic.

If you look in the source code, I think in Parser.cs or Lexer.cs it explains that they have the code to manage xref streams but they haven't implemented it yet.

I guess it is planned for a next release but I haven't heard anything official.

I've had to do some modification to another area of the library for something else so I'm thinking I may have to read up on xref streams and this myself as well.

Regards,

Billy
