I'm looking for a lib that gives me the possibility to delete some pages of an existing pdf and store it in PDF/A-2u Format.
The source PDF is already in this Format. I tried a lib of opentext. There it worked but the resulting PDF-Format is not PDF/A after the necessary changes. I wasn't able to store it in the original Format.
Can you give me some hints how to delete single pages of an existing PDF/A File?
