NAME

       jng - JPEG Network Graphics (JNG) sub-format

DESCRIPTION

       JNG  (JPEG Network Graphics) is a sub-format of the MNG (Multiple-image Network Graphics) format. As with MNG it extends on the features of
       the popular PNG (Portable Network Graphics) image-format.

       This sub-format was designed to support a lossy compression-method.  It is based completely on the JPEG specification. It  adds	the  high-
       compression ratios of JPEG for photographic images.

       As  a  member of the Network Graphics family, JNG was deemed adequate as a stand-alone format as it extends the JPEG format with color-cor-
       rection and transparency features.

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.
