There are certain areas of PDF development that programmers have to be
careful of not 'treading upon' - ie: Tampering with the Reader
Extensions that implement user rights. However, the rest of the PDF
format specifications are publicly available for developers to implement
their own solutions.
From Adobe's own site @
http://www.adobe.com/devnet/pdf/pdf_reference.html: "This book provides
a description of the PDF file format and is intended primarily for
developers of /PDF producer/ applications that create PDF files
directly. It also contains enough information to allow developers to
write /PDF consumer/ applications that read existing PDF files and
interpret or modify their contents."
