PDFLib is a simpler, more OO interface to pdflib, available
from http://www.pdflib.com/

Currently it supports text, images, and getting/setting all
parameters. It has builting support for several paper sizes.
It also takes care of starting/ending new pages, to try and
make sure that a valid PDF file is always created (though
unfortunately I think it's still possible to create an invalid
PDF with this module).

Support for graphics primitives is planned.

This is free software, you may distribute it under the same
terms as Perl itself.
