%description
    The Portable Network Graphics (PNG) format is a image format with
    lossless compression. It was designed to replace the older and
    simpler GIF format and, to some extent, the much more complex TIFF
    format. PNG supports up to 48-bit truecolor or 16-bit grayscale
    saving, alpha channels (variable transparency), gamma correction
    (cross-platform control of image brightness), and two-dimensional
    interlacing (a method of progressive display).
