Program information
-------------------
akTIFF.datatype is a TIFF datatype, which is based on the
latest TIFF reference sources (libtiff 3.4beta037).
So it does support 8 Bit color mapped files (colorspace expanded to
8 bit per component always) and True color files (24 Bit, alpha
channel ignored, cut down to 24 Bit 8:8:8 if necessary).
Note, that reading of LZW compressed TIFF graphics is disabled because
of legal reasons. Zip and JPEG compression intentionally is not supported,
because they are seldomly used and support would bloaten the binaries
a lot - subject to further considerations, though.
[ More detailed description can be found in akTIFF.guide ]
--------------------------------------------------------------------------
Supported output bitmap formats:
- picture.datatype V39-42:
o (upto) 256 palette colors
o HAM6 or HAM8
- picture.datatype V43 (CyberGraphX or Picasso96 *) or V44 (OS 3.5)
o 24 Bit RGB
Where upto 256 colors always will be exported unmodified,
and 24 Bit data either is dithered or converted to HAM6/HAM8,
if it can't be or should not be exported unmodified.
(*) the latter one works with OCS/ECS/AGA, too
