Does PDFNet support PDF/X or PDF/E?
Standards such as PDF/X and PDF/E define a subset of the PDF specification designed for a specific industry (e.g. publishing, engineering, etc). PDFNet allows processing and generation of any PDF document, and it does not prevent the user from creating a valid document that includes features that are not listed in one of PDF subsets. To make your application PDF/X (or PDF/E) compliant, you need to make sure that you are using only PDF features allowed by a given subset.
