Member IDRSNET.Aes128: Required PDF version 1.6 or higher
Member IDRSNET.Basic: Please note that this format doesn't allow multipage outputs yet, and CDocumentWriter will throw an exception if the case occurs. This possibility will be added in a future release.
Member IDRSNET.Maximum: This mode uses a lot of memory in case of zonal OCR with several contexts.
Member IDRSNET.Rc4: Please note that RC4 is considered insecure, but allows to apply encryption on PDF versions 1.4 and 1.5. If possible, prefer generating PDF versions 1.6 or later with AES 128 encryption.
