libpng

http://www.libpng.org/pub/png/libpng.html
A collection of routines to create and manipulate PNG format graphic images. Designed as a replacement for GIF (and to a lesser extent TIFF) due to functional and patent problems, with more efficient compression (using Gzip-like DEFLATE), support for 24-bit color and alpha transparency.
