PDFsharp & MigraDoc Forum

Hi Guys

I am using version 1.2.1269.0 of the pdf sharp library and it has been working fine for several months. I have received the following error message for a couple of PDF files recently and would like to identify what the problem with these files might be.

Assertion Failed - not implemented

at Lexer.ScanNextToken()
at Parser.ReadInteger(Boolean canBeIndirect)
at Parser.ReadInteger()
at Parser.ReadObject(PdfObject pdfObject, PdfObjectID objectID, Boolean includeReferences)......

My code basically takes a list of pdf files, iterates the pages for each pdf file and adds the page to a new pdf document, essentially merging a selection of pdf files into one file.

I can provide a copy of the PDF file that is causing the problem.

Thanks in advance
