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
There are no new features in this release (compared to jpegAGA 2.0), only a
bug has been fixed.
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
