Needs Kickstart V3.x 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.
