I need to be able to use Spire.PDF to compare/contrast PDF documents page by page and give a resulting PDF of just the differences between the two documents.
Is this something Spire.PDF can handle? I see where you have text extraction but we do not have Spire.DOC license so converting and comparing is not an option for us, but I need to have a final PDF that is based on the original PDF with highlighted area's of change, so PDF1 is source, PDF2 is to compare to, generate PDF3 from a copy of PDF1 highlighting the changes.
