- This archive contains the PCHG (Palette CHanGe) IFF chunk specs and tools.
- The new IFF chunk PCHG allow to specify line-by-line palette changes in a
- simple way which is independent of the video mode; while it allows up to
- 65536 registers, it's usually shorter of an equivalent CTBL or SHAM chunk.
- Library code with full source and documentation is provided for a
- straightforward implementation in your programs. PCHG has been developed in
- BIX through an open discussion of many Amiga programmers, and it is our hope
- that it will become the Amiga standard for palette change technology. The
- difference between the current release of this archive and release 1.2 are a
- recompilation, an update of the included tools, and a fix of a couple of
- minor bugs.
-
- Included in the archive is the latest version of Mostra (2V15), which
- features full PCHG support, and MakeVPort_Patch, which installs a small
- patch to MakeVPort() that fixes a small bug of user copper lists under 2.04.
- The bug is non-existent under 3.0.
-
- LightHouse and Lake are two very impressive multipalette pictures converted
- by Ed Hanway's HamLabPlus. Mostra will allow you to look at LightHouse in
- AUTOSCROLL mode.
-
- Documentation about the format is provided in Texinfo, dvi, AmigaGuideĀ® and
- PostScript format (PCHG.texinfo, PCHG.dvi, PCHG.guide and PCHG.ps).
- Documentation about the support routines is provided in standard Autodoc
- format.
-
- The ToPCHG program is a dirty hack mainly useful for producing test pictures.
- Documentation is included in the source file.
