Wad2PDF examines wad files and prints an overhead picture of all levels to a PDF file.
Wad2PDF is a program that converts the levels in Doom wad files into PDF files. The result has a birds eye view of every level, with floors neatly texturized and all items in the level in their proper places.
The PDF output can be imported to graphics programs for further editing or printed out directly. You can even create wall-sized mega posters of your favorite Doom levels.
Main features:
- supports all Doom games: Ultimate Doom, Doom II, Heretic, Hexen, and Strife
- full pwad support
- creates browsable PDF with bookmarks identified by level names
- reads gl nodes both from wads and GWA files
- resulting PDF is vectorized and can be zoomed arbitrarily (extreme zooms will make the textures blocky, though)
- available under the GPL
- does not support hi-res graphics or scaled/zoomed flats

PoDoFo library is a free, portable C++ library. PoDoFo library can parse existing PDF files and create new ones from scratch.

PoDoFo is a library to work with the PDF file format. The name comes from the first letter of PDF (Portable Document Format). A few tools to work with PDF files are already included in the PoDoFo package.

The PoDoFo library is a free, portable C++ library which includes classes to parse PDF files and modify their contents into memory. The changes can be written back to disk easily. The parser can also be used to extract information from a PDF file (for example the parser could be used in a PDF viewer).

Besides parsing PoDoFo includes also very simple classes to create your own PDF files. All classes are documented so it is easy to start writing your own application using PoDoFo.

As of now PoDoFo is only available for Unix platforms. But the code is portable C++ and a Windows version will be available soon.

pdfTeX is an extended version of TeX that can create PDF directly from TeX source files and enhance the result of TeX typesetting with the help of PDF.
When PDF output is not selected, pdfTeX produces normal DVI output, otherwise it produces PDF output that looks identical to the DVI output.
An important aspect of pdfTeX project is to investigate alternative justification algorithms, optionally making use of multiple master fonts.
Enhancements:
- This includes xpdf 3.02pl1, fixing some security problems.

PdfRipImage is a utility to extract images from PDF documents and convert them to a format of your choice. You can choose to extract whole pages or just the images contained in them.
