I've got a PDF file that I OCR'd using Mobi PDF. Normally Mobi just modifies the page to add the OCR'd text with rendering mode 3 (neither fill not stroke) but sometimes (maybe when the file has enough pages) it instead does an incremental update with a cross reference section (/XRef) and corresponding object stream (/ObjStm). When I've got a file with an incremental update, PdfDocument.Pages returns the original (pre-update) pages instead of the modified versions.

Is this a known deficiency in PdfSharp, or am I using it wrong? Maybe there's a flag I'm supposed to set somewhere to tell PdfReader to pay attention to the updates?

Does PdfSharp "notice" PDFs with incremental updates?
Yes.

Are you using version 6.2.0 Preview 2?

I'm using the latest release version (6.1.1). Is there reason to believe 6.2.0 solves this?

We have no PDF to test with. No feedback if it works with 6.2.0 Preview 2.
So there is nothing we can do about it.
