Program information
-------------------
akLJPG.datatype is a new JPEG datatype, which is based on the
Lossless JPEG Codec V1.0 - which implements a lossless JPEG format not
directly related to the JFIF JPEG file format.
It supports reading of LJPG graphics files.
LJPG is a freely distributable lossless JPEG image compression package.
There's a port of the encoding program "pnmtoljpg" available on Aminet
as gfx/pbm/pnmtoljpg.lha, which compresses a Portable Pixmap (PPM, PNM-P6)
or Portable Graymap image (PGM, PNM-P5) to a lossles JPEG (LJPG) image
using the JPEG standard (DIS) lossless mode of operation.
This datatype decodes a ljpg image to either 24 Bit RGB or 256 grayscales
depending on the number of color components stored in the LJPG image file.
--------------------------------------------------------------------------
Supported output bitmap formats:
- picture.datatype V39-42:
o (upto) 256 palette colors
o HAM6 or HAM8
- picture.datatype V43 (CyberGraphX or Picasso96) (*)
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
