Program information
-------------------
akLJPG.datatype is a new JPEG datatype, which is based on the
Lossless JPEG Codec V1.0 - which is 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.
With V39-V42 picture.datatype it either produces (upto) 256 color
palette-based or HAM6/8 output (256 colors exported unmodified,
24 Bit data either dithered or converted to HAM6/HAM8) with
Ralph Schmidt's picture.datatype V43 24 Bit may be done unmodified
(the same applies to Picasso96's picture.datatype V43).
You must use the included preferences program for best configuration.
See program archive for copyright and distribution information.
