    <ns3:description xml:lang="en">Portable Network Graphics (PNG) was designed for the lossless, portable, compressed storage of raster 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 bits. PNG is designed to work in online viewing applications, so it is fully streamable.  It can store gamma and chromaticity.  PNG also detects file corruption.</ns3:description>
