Hi,
We are using Aspose.PDF in .NET to convert PDF documents to XPS so that we can use the DocumentViewer in WPF to display the documents.
We have noticed that PDF filed created some scanners that embed hidden OCR text in the PDF do not display well. The hidden text is visible, and at best leaves an unpleasant shadow behind the scanned text. At worst, the text becomes unreadable.
I have attached a Visual Studio solution that reproduces the problem. (The sample document used comes from another thread on your forums http://www.aspose.com/community/forums/permalink/403827/403827/showthread.aspx#403827.)
