         png - Portable Network Graphics (PNG) format
         PNG (Portable Network Graphics) is an extensible file format
         for  the lossless, portable, well-compressed storage of ras-
         ter images. PNG provides a patent-free replacement  for  GIF
         and  can  also  replace  many  common uses of TIFF. Indexed-
         color, grayscale, and truecolor images are  supported,  plus
         an  optional alpha channel. Sample depths range from 1 to 16
         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 option. PNG is  robust,  providing  both
         full  file  integrity checking and fast, simple detection of
         common transmission errors. Also, PNG can  store  gamma  and
         chromaticity data for improved color matching on heterogene-
         ous platforms.
