Short: Highest quality JPEG viewer (for AGA) Author: Guenther@studbox.uni-stuttgart.de (Guenther Roehrich) Uploader: Guenther@studbox.uni-stuttgart.de (Guenther Roehrich) Type: gfx/show jpegAGA is, at this time, the highest quality JPEG viewer (if a map-file for that picture is available) To use it you need the AGA chipset, a 68020 or higher processor and OS 3.0 or higher. This program uses the HAM8-mode, gray- scale display will use 256-color-mode. Although jpegAGA 2.0 has many new features it is still fully compatible to the previous versions. If a precomputed colormap (a file with the ending .map) is available then the picture will be displayed in a much higher quality compared to all other viewers. History ******* 1.0 - 4-June-1994 - first public release 1.1 - 5-October-1994 - added the option -SUPER72 - the picture screen no longer flashes when closing it and the delay is much smaller now - map-files will also be searched in the directory pointed to by the MAPDIR environment variable - if a map-file is not found the user will get informed that he/she should create one - file/path names of any length are now accepted 2.0 - 14-January-1995 - slightly faster - the ixemul.library is not needed any more - version 5A of the JPEG source from the Independent JPEG Group is used (instead of V4 in jpegAGA 1.x) - input buffer size is now 32768 bytes, normal dos.library calls will be used for all file operations - added the options -SCALE, -FIT, -NOSMOOTH, -DCT FAST and -SMR - added the background loading feature - pressing the Esc button will completely stop the program, pressing the right mouse button switches to the next picture - the picture screen opens with the correct colors, no flashing after opening - multiple files and wildcards are supported, at any place in the command line - selecting the pictures with a file requester is possible - full Workbench support, but there is still no GUI - messages in the console window are much better - there is now a makefile for the Aztec compiler supplied with the source - enhanced the HAM8 encoder, if you move the picture screen around the errors on the left side will be much smaller
