Starting with v2014R1, when enforcing permissions within a PDF document, Qoppa’s libraries check against 3 permissions types. The existing API was modified to reflect this change.

  1. Document Permissions – when the document is encrypted.
  2. DocMDP Permissions – when the document has a certifying signature.
  3. Usage Right Permissions – when the document is Adobe Reader enabled. Qoppa’s jPDFProcess and jPDFSecure are now able to preserve on Save, enforce and clear document usage rights in PDF that have been “Adobe Reader Enabled” PDFs).
