PNG: The Definitive Guide

A free book about the PNG image format.

This book was published by O'Reilly and it has three parts:

  - Part I, Using PNG, consists of six chapters and covers the main categories
    of PNG-supporting applications: image editors, viewers, converters, web
    browsers and servers, and 3D apps.
  - Part II, The Design of PNG, also consists of six chapters and looks in
    more detail at PNG as a file format. It covers not only PNG's fundamental
    chunk structure and compression technology but also its history, its
    animated cousin MNG, and some of the intricacies of cross-platform gamma
    and color correction.
  - Part III, Programming with PNG, steps the reader through the design of
    three functional demo programs based on the free libpng C library: rpng,
    a very simple PNG viewer; rpng2, a progressive PNG viewer such as might be
    found in a web browser; and wpng, a basic program to convert RGB image
    data from binary PBMPLUS / NetPBM format into PNG format. The final chapter
    in this section lists a number of other PNG-supporting programming toolkits
    for various languages, including C, C++, Java, Perl, Python, tcl/tk, and
    Visual Basic.
