The above exception is being generated when I attempt to sign a PDF that was produced using the Print to PDF option under Mac OS X.
Attached is the PDF generating the error.
Using Aspose.pdf.dll version 220.127.116.11
The application code is the same as my previous problem.
I have updated the Web app at
