     <file format> /ping/ (PNG) An extensible file format for the
     lossless, portable, well-compressed storage of raster images
     .  PNG provides a patent-free replacement for GIF and
     can also replace many common uses of TIFF.
     Indexed-colour, greyscale and truecolour images are
     supported, plus an optional alpha channel.  Sample depths
     range from 1 to 16 bits.
  
     PNG is designed for on-line 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 simple detection of common
     transmission errors.  Also, PNG can store gamma correction
     and chromaticity data for improved colour matching on
     heterogeneous platforms.
