Recently I tried to compile PoDoFo on Windows using Mingw, so i did some researches, and found 6 projects that use PoDoFo as PDF editing library.

• PoDoFoBrowser

PoDoFoBrowser is developed with Qt4 by the same author of PoDoFo, a gui for editing the object structur of PDF files directly.

• Scribus

Scribus is an Open Source program that brings award-winning professional page layout to Linux/UNIX, Mac OS X, OS/2 Warp 4/eComStation and Windows desktops with a combination of “press-ready” output and new approaches to page layout.
Underneath the modern and user friendly interface, Scribus supports professional publishing features, such as CMYK color, separations, Spot Colors, ICC color management and versatile PDF creation.

• Calibre-ebook

calibre is a free and open source e-book library management application developed by users of e-books for users of e-books

• Comment

Comment is a PDF annotator (tailored to the author’s needs as a mathematician who wants to comment articles and save the comments for later reference with the pdf files).

• OkularAnnotMerge

OkularAnnotMerge is a quick and dirty hack to merge okularannotations (saved in a xml separate from the annotated file) into the pdf.

P.S.

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.
PoDoFo is written in C++ and the code was sucessfully compiled under Unix, Mac OS X and Windows.

Swf2XNA is an open source program under BSD license, developed in C#, with it , you can make Windows/XBox/Win7 games by leveraging Flash for assets and layout, as well as using Box2D visually. It makes 2D games in XNA quite simple to make!

Introduction
The aim of “Java Decompiler” project is to develop tools to decompile and analyze Java 5, and upper, “.class” files.
Some facts:
* The final release of JSR 176, defining the major features of the J2SE 5.0, has been published the september 30, 2004.
* The lastest Java version supported by JAD, the famous Java decompiler written by Mr. Pavel Kouznetsov, is 1.3.
* Most of Java decompilers downloadable today from Internet, such as “DJ Java Decompiler” or “Cavaj Java Decompiler”, are powered by JAD : they can not display Java 5 sources.

Main features
* JD-Core and JD-GUI are written in C++. This allows an extremely fast decompilation and a display.
* JD-Core does not require the Java runtime environment for its functioning, therefore no special setup is required.
* JD-Core works with most current compilers including the following:
o jdk1.1.8
o jdk1.3.1
o jdk1.4.2
o jdk1.5.0
o jdk1.6.0
o jikes-1.22
o harmony-jdk-r533500
o Eclipse Java Compiler v_677_R32x, 3.2.1 release
o jrockit90_150_06
* JD-Core supports the following new features of Java 5:
o Annotations
o Generics
o Type “enum”
* JD-GUI supports Drag and Drop.
* JD-GUI supports JAR files.
* JD-GUI displays color coded Java source code.
* JD-GUI allows you to browse the “class” files hierarchy.
* JD-GUI displays “log” files, and allow you to decompile “class” files appearing in Java stack traces.
* JD-Core and JD-GUI use the excellent cross-platform wxWidgets toolkit.
