libpng is the official PNG reference library. It supports almost all PNG features, is extensible, and has been extensively tested for over 12 years. libpng is available as ANSI C source code and requires zlib 1.0.4 or later (1.2.3 or 1.1.4 ... [More] recommended due to potential security vulnerabilities in earlier versions). In addition to the main library sources, libpng includes the rpng, rpng2 and wpng demo programs, the pngminus demo program, a subset of Willem van Schaik's PngSuite test images, Willem's VisualPng demo program, and Intel's MMX-optimized routines for faster decoding on x86-class CPUs (currently for Microsoft Visual C++ and GNU C only; the two versions are equivalent aside from a thread-safety issue in the latter port).

GD is an open source code library for the dynamic creation of images by programmers. GD creates PNG, JPEG or GIF, among other formats. GD is commonly used to generate charts, graphics, thumbnails, and most anything else, on the fly. While not restricted to use on the web, the most common applications of GD involve web site development.

Imager is a toolkit for manipulating images from perl.

Asido is a PHP (PHP4/PHP5) image processing solution, with pluggabledrivers(adapters) for virtually any environment.

NGI is a generic image processing and image analysis library. Let us dissect the important terms of this definition. Image processing is the global name for programming techniques that deal with images on input and recreate other images on ... [More] output. Image analysis goes a step further in that it tries to extract meaning from an image. Usually the output of an image analysis algorithm is not another image, but some different data, such as the number of objects in an image. Library is the term for a piece of code that's available in the form of a toolbox. Software pieces to be assembled by a programmer to fulfill a task. The NGI library is a C++ library available in source code. Generic is the opposite of specific. Read more at http://code.google.com/p/ngi/ [Less]

Png++ aims to provide a simple yet powerful C++ interface to libpng, the PNG reference implementation library. Using raw libpng in C++ may impose a serious challenge since lots of precautions must be taken to handle initialization/deinitialization ...
