XFINIUM.PDF 6.6 brings support for PDF/A-2 and PDF/A-3. PDF/A (ISO 19005) is an ISO-standardized version of the PDF format specialized for use in the archiving and long-term preservation of electronic documents.
PDF/A-1B (part 1 of ISO 19005) was already supported, with v6.6 we add support for PDF/A-2 (ISO 19005 part 2) and PDF/A-3 (ISO 19005 part 3).
PDF/A-2 builds on top of PDF/A-1 and includes additional support for transparency, optional content and document attachments (the attachments must in PDF/A-1 format). PDF/A-3 builds on top of PDF/A-3 and allows all types of document attachments.
Both PDF/A-2 and PDF/A-3 have 3 conformance levels: A, B and U. XFINIUM.PDF supports conformance levels B and U for both PDF/A-2 and PDF/A-3.
The code below shows how to create a PDF/A-2B file.
