[PNG icon] Portable Network Graphics (PNG) Specification, version 1.2

This is version 1.2 of the specification for the Portable Network Graphics image format. This version was partially superseded by the joint W3C and ISO/IEC version on 10 November 2003. However, the International Standard currently is available only in single-page HTML format, and it omits the very useful Gamma and Color tutorials present in this version. On the other hand, it does include several completely new color figures that may prove useful to some. (Technical differences between the two versions are virtually nonexistent and consist solely of minor clarifications.)
