Hello,
we have large PDF (over 2GB) we want to scan and check whether it is signed or not.

When trying to open we got ArgumentOutOfRangeException.
Found PdfDocumentOpenMode.InformationOnly option, but it also seems to load whole document to memory and fails.

However we dont need to access all data of the file. Is there any way to read just some data (like signature) when opening the the stream?

Thank you, nice day,
Fitik
