Short: AkLJPG-dt V43.90 (LJPG, 68000-060) Author: Andreas_Kleinert@t-online.de Uploader: Andreas_Kleinert@t-online.de Type: util/dtype Replaces: akFix4381.lha (68000, 020/030, 040 and 060 versions inside) ***************** NEWS FLASH ***************** V43.90 (24.06.97) : - V43.81 should had been available as binary-only fix archive "akFix4381.lha" together with the other datatypes, only. Upload did not succeed (-> a zillion people did report V43.80 bug) - added akDT_Installer by Robert C. Reiswig (-> Robert C. Reiswig, akDatatype@vgr.com) V43.81 (16.06.97) : - prefs icon was renamed differently than program (-> detected by Roger Hagensen) - new dispatcher code either still is buggy, only works with V45 or has been implemented wrongly. Anyway: V43.80 was messed up, better use V43.81 !! - prefs icon had be wrongly named (-> Roger Hagensen, Andreas Schwarz) ***************** NEWS FLASH ***************** akLJPG.datatype - licenseable FREEWARE - © 1997 by Andreas Ralph Kleinert.

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.
