NAME

       gif2apng -  convert animated GIF to animated PNG files

SYNOPSIS

       gif2apng <INPUT *.gif> [<OUTPUT *.png>] [options]

DESCRIPTION

       Progrmam converts animated GIF into animated PNG format. Wu64 quantization is used for true-color files. Transparency is handled either
       using a threshold, or composed over chosen background color.

       The Animated Portable Network Graphics (APNG) file format is an extension to the Portable Network Graphics (PNG) specification. It allows
       for animated PNG files that work similarly to animated GIF files, while retaining backward compatibility with non-animated PNG files and
       adding support for 8-bit transparency and 24-bit images.

OPTIONS

       -kp Keep original palette from GIF and do not optimize it for PNG.

ENVIRONMENT

       None.

FILES

       None.

STANDARDS

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.
