PDF-X OCR SDK is a New product from us and intended to compliment our existing PDF and Imaging Tools to provide the Developer with an expanding set of professional tools for Optical Character Recognition tasks
I did speak to one of the dev team about this. He told me the issue is reproduced and to make a formal support request ticket around this. While intended for internal use only, if you refer to RT#5394: Wrong PDF when using OCR_MakeSearchable in correspondence with us then any support staff member can get yo a status update on the ticket.
Back to the issue itself, you should see a post here with some suggestions withing 24 hours.
If posting files to this forum - you must archive the files to a ZIP, RAR or 7z file or they will not be uploaded - thank you.
We've inspected this behavior and it seems that it's a bug. Part of the content is not being rendered and the SDK does not know about it.
But, as a temporary fix, you can try using the additional flags: OCR_Content_Original and OCR_Image_SuppressOutput. Then the text that is being lost in the rendering process will be left as is and the text for search will be put on top of it.
