PDFio is a simple C library for reading and writing PDF files. I’ve been working on it sporadically for the last few weeks to prototype some new printing features and support a future version of HTMLDOC. The primary goals of PDFio are:
PDFio is not concerned with rendering or viewing a PDF file, although a PDF RIP or viewer could be written using it. And while it is far from complete, the current code is sufficient to manipulate PDF files and create page content.
I’m providing PDFio under the Apache License Version 2.0 with an (optional) exception to allow linking against GPL2/LGPL2 software.
