Architecture: ppc-morphos

This is MorphOS port of libmng. It is based on libmng 1.0.10 (13th July 2007).

 System requirements
 -------------------

 * MorphOS 2 or MorphOS 1 with Update Pack v1.0
 * littlecms.library V3


 Version history
 ---------------

 mng.library version 2.0:
 * fixed bug in library startup code
 * now requires littlecms.library V3 as minimum

 mng.library version 1.1:
 * fixed bug in auto-open libraries (developers only)
 * optimised library code

 mng.library version 1.0:
 * first public release


MNG features:

 * object or sprite-based approach to animation, with commands to move, copy
   and paste images (rather than replicate them as in GIF)
 * nested loops for complex animations
 * way better compression than GIF animations
 * support for difference (or "delta") images for still better compression
 * integration of both PNG and JPEG-based ("JNG") images
 * support for transparent JPEG images
 * low-complexity and very low-complexity subsets for simpler implementation


MNG shares a number of PNG's features:

 * ultra-clever magic signature that can detect the most common types of file corruption
 * non-patented compression, either completely lossless (PNG) or lossy (JPEG)
 * full alpha support (multi-level transparency) for all image objects
 * gamma and color correction for cross-platform consistency
 * ability to store copyright and other textual info, either compressed or uncompressed
