UPDATE: We had a multipage document which went through the same process as posted below. It appears that this document was processed successfully. I don't know why having a registered copy changes things but it is almost as if the buffer isn't flushed if the document is <= a single buffer.
The section for case "Scoping" is the PDF document process. This is the 3rd bug we've encountered with using Aspose. As a note: while the code below generates a blank document, when we load the pages in the same manner and save the pages as an image, all of the data displays correctly in the image. Go figure.

You’d never get it working. The code I sent you is basically what we are doing. I did notice after posting that we are currently running 7.6 instead of 7.9. I’m in the process of upgrading to see if that fixes the issue.
