overview
-----------------------------
- c2p.library is a fast lowlevel Amiga shared library for chunky2planar
conversion.
- c2p.library is designed to run the core loop entirely into the CPU
instruction cache, resulting a very fast conversion.
- being a standard Amiga shared library, you can use c2p.library with
your favourite development language.
- c2p.library can convert chunky data in any resolution, up to 2 Mpx.
- c2p.library is released under the MIT license.
features
-----------------------------
- convert 8 bit chunky buffer to 1-8 bitplanes planar Bitmap
- fully OS compliant
- automatic CPU detection to select the best conversion algorithm
- sources included
- fully documented
- supplied with SDK for C, Assembly and Amiga E
- free to use, for any personal or commercial software
requirements
-----------------------------
- os3.x (v39) or newer
- CPU 68020 or greater
recent changes
-----------------------------
v1.3
- you can choose to convert only a limited number of chunky
pixels, selecting them using a source offset and placing the
result using a destination offset (eg: useful for chunky
Blitter objects).
v1.2
- ability to use custom bitmaps.
v1.1
- optimized conversion algorithm for processors with bigger
instruction cache (Motorola 68040 or greater).
v1.0
- first public release.
