This is a JPEG viewer for MM/1 and MM/1a based on the IJG JPEG library
version 5a. It has been compiled with GNU gcc ver. 2.5.8, separately for MM/1
(file jpegshow.070, compiled with option -m68000) and for MM/1a (file
jpegshow, compiled with option -mcpu32).
For the list of options and their current settings type "jpegshow -?". They
include:
-1 for single pass, quick but low quality picture
-p for setting the delay length after each picture. -1 means wait for user
typing CR, 0 means no delay
-sn where n = 1, 2, 4 or 8, to scale down the size of the picture by this
factor
-xn, -yn where n = 0 to 99, to start displaying the picture at this offset
(in percent of the total size)
I am thinking of a better user interface to this program, using the mouse
and the scroll bars to move the picture. This will be for the next version ...
The source is included and it is surprisingly simple, most of the function-
ality given by the Independent JPEG Group's library.
Enjoy,
