I am studying PoDoFo now, and want a better IDE to work with MinGW, after some search, I decided to use Code::Block(aka CB or CodeBlocks). At office I have easily downloaded the Windows setup package, but when I tried to download at home several times without success and the error message is Too many Clients!.
So I uploaded it to my project hosting at Google Code,
please use another mirror.

• codeblocks-10.05-setup.exe   22.2 MB
• codeblocks-10.05mingw-setup.exe   70.6 MB(includes the GCC compiler and GDB debugger from MinGW)
• Another download mirror:codeblocks-10.05mingw-setup.exe   70.6 MB(includes the GCC compiler and GDB debugger from MinGW)

P.S.

Code::Blocks is a open source, cross platform, free C++ IDE built to meet the most demanding needs of its users. It is designed to be very extensible and fully configurable.
Finally, an IDE with all the features you need, having a consistent look, feel and operation across platforms.
Built around a plugin framework, Code::Blocks can be extended with plugins. Any kind of functionality can be added by installing/coding a plugin. For instance, compiling and debugging functionality is already provided by plugins!

libjpeg is a library written entirely in C which contains a widely-used implementation of a JPEG decoder, JPEG encoder and other JPEG utilities. This library is maintained by the Independent JPEG Group.

libjpeg-turbo is a high-speed version of libjpeg for x86 and x86-64 processors which uses SIMD instructions (MMX, SSE2, etc.) to accelerate baseline JPEG compression and decompression. libjpeg-turbo is generally 2-4x as fast as the unmodified version of libjpeg, all else being equal(for non-grayscale JPEG compression and decompression, libjpeg-turbo is between 1.8x and 4.5x as fast as libjpeg v6b).

libjpeg-turbo was originally based on libjpeg/SIMD by Miyasaka Masaru, but the TigerVNC and VirtualGL projects made numerous enhancements to the codec, including improved support for Mac OS X, 64-bit support, support for 32-bit and big endian pixel formats (RGBA, ABGR, etc.), accelerated Huffman encoding/decoding, and various bug fixes. The goal was to produce a fully open source codec that could replace the partially closed source TurboJPEG/IPP codec used by VirtualGL and TurboVNC. libjpeg-turbo generally achieves 80-120% of the performance of TurboJPEG/IPP. It is faster in some areas but slower in others(for non-grayscale JPEG compression and decompression, libjpeg-turbo 64-bit is between 80% and 118% as fast as TurboJPEG/IPP. libjpeg-turbo 32-bit is between 60% and 93% as fast as TurboJPEG/IPP. libjpeg-turbo’s primary weakness relative to TurboJPEG/IPP is 32-bit performance, particularly on Intel processors and even more particularly on legacy Intel processors. This is largely due to the Huffman encoder/decoder running out of registers and having to swap some inner loop variables back and forth from memory).

In one word, libjpeg-turbo is a fork of libjpeg that uses SIMD instructions to accelerate JPEG encoding and decoding.

btw, projects such as Mozilla and fedora switched to libjpeg-turbo in 2010.

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.
