FEATURES

- Supports both normal and interlaced PNG files

suit your monitor/environment

- Alpha channel handling can be configured to output RGBA bitmaps, or
RGB bitmaps either by combining the alpha information internally
using a configurable background colour or simply stripping it

- Highly optimized datatype dispatch engine, and fast PNG decoder,
resulting in a very efficient, compact and quick PNG datatype

- Asynchronous file i/o and double buffering techniques (WarpOS only),
which speeds up image decoding

- PowerPC support with native OS4, WarpOS and MorphOS versions

- Alter the pen allocation precision when images are remapped to an
8-bit display
