This package reads and writes any document that conforms to the PDF specification generously provided by Adobe at http://partners.adobe.com/public/developer/pdf/index_reference.html The file format is well-supported, with the exception of the "linearized" or "optimized" output format, which this module can read but not write. Many specific aspects of the document model are not manipulable with this package (like fonts), but if the input document is correctly written, then this module will preserve the model integrity. This library grants you some power over the PDF security model. Note that applications editing PDF documents via this library MUST respect the security preferences of the document. Any violation of this respect is contrary to Adobe's intellectual property position, as stated in the reference manual at the above URL. WWW: http://search.cpan.org/dist/CAM-PDF/
