CAM::PDF is a Perl library for reading and modifying existing PDF files

CAM::PDF is a Perl library for low-level reading and modification of existing PDF files. It is very fast, but it cannot create PDF files from scratch nor does it include a high-level API for document editing. It originated at Clotho Advanced Media, hence its name. See http://search.cpan.org/dist/CAM-PDF/lib/CAM/PDF.pm
