NAME

       mng - Multiple-image Network Graphics (MNG) format

DESCRIPTION

       MNG  (Multiple-image  Network  Graphics)  is the animation extension of the popular PNG image-format. PNG (Portable Network Graphics) is an
       extensible file format for the lossless, portable, well-compressed storage of raster images.

       MNG has advanced animation features which make it very useful as a full replacement for GIF animations.	These  features  allow	animations
       that are impossible with GIF or result in much smaller files as GIF.

       As  MNG builds on the same structure as PNG, it is robust, extensible and free of patents. It retains the same clever file integrity checks
       as in PNG.

       MNG also embraces the lossy JPEG image-format in a sub-format named JNG, which allows for alpha-transparency and color-correction on highly
       compressed (photographic) images.

NAME

       png - Portable Network Graphics (PNG) format

DESCRIPTION

       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-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 well in online viewing applications, such as the World Wide Web, so it is fully streamable with a progressive dis-
       play 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 heterogeneous platforms.
