NAME
     png - Portable Network Graphics format

DESCRIPTION
     The png library contains functions dealing with files in the PNG format.
     PNG (Portable Network Graphics) is an extensible file format for the
     lossless, portable, well-compressed storage of raster images. PNG pro-
     vides a patent-free replacement for GIF and can also replace many common
     uses of TIFF. Indexed-colour, grayscale, and truecolour images are sup-
     ported, plus an optional alpha channel. Sample depths range from 1 to 16
     bits.

     PNG is designed to work well in online viewing applications, such as the
     World Wide Web, so it is fully streamable with a progressive display op-
     tion. PNG is robust, providing both full file integrity checking and
     fast, simple detection of common transmission errors. Also, PNG can
     storegamma and chromaticity data for improved colour matching on hetero-
     geneous platforms.

FILES
