MNG(5)                   DragonFly File Formats Manual                  MNG(5)


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.
