This is version 0.1 of JpegShow (07Aug01) the JPEG slideshow viewer
for the Atari 8-bit computers.  It is based on Juddpeg, the JPEG
decoder and viewer for the C=64, written by Stephen L. Judd and Adrian
Gonzalez (http://www.ffd2.com/fridge/).  The Atari 8-bit versions use
a modified version of Stephen's decoder along with 3 new interfaces:

a8jdpeg 0.8 (14Sep02) - The original Atari interface
JpegView 0.2 (07Aug01) - A friendlier menu oriented version
JpegShow 0.1 (07Aug01) - A slideshow version

The newest versions are available from  http://a8jdpeg.atari.org  or
http://a8jdpeg.webhop.org

A note for SpartaDOS users:
The display modes marked as 64K really really do need 64K! This includes using
the RAM under the OS.  Most versions of SpartaDOS also use this area
and your machine *WILL* crash if you use a 64K display mode with one of these
SpartaDOS versions.  The 48K modes should work though.  If you do want
to use a 64K display mode with a SpartaDOS disk, then give BEWEDOS a
try.

CONVERTING IMAGES:
a8jdpeg and JpegView can both convert JPEGs to the Atari 8-bit
Micropainter and HIP formats.  If these don't suit you, or if you want
access to the uncompressed image data for whatever reason, then
a8jdpeg can also convert to PGM (Portable Greymap) format.  This
format can easily be read on the Atari 8-bit (and many other machines) 
and converted to whatever format suits you.  An example BASIC program
for reading the PGMs produced by a8jdpeg can be found at either
http://a8jdpeg.atari.org  or  http://a8jdpeg.webhop.org

SUPPORTED JPEGs:
This version should work fine on most baseline JPEGs out there.
It will not work on progressive JPEGs.  Progressive JPEGs are designed 
for viewing over a slow connection.  When viewing a progressive JPEG
over a slow connection, it starts out as a low quality fuzzy image which
becomes clearer as more data is downloaded.  The way progressive JPEGs 
are implemented makes then harder (although not impossible) to handle in
48/64K of RAM.

Progressive JPEGs can be converted to baseline JPEGs using the
jpegtran program provided by the IJG (The Independent JPEG Group):

jpegtran input.jpg > output.jpg

Then try displaying the new image. This may also fix other problems
with images too.  The jpegtran program is available for many systems,
although not (unfortunately) for the Atari 8-bit.  If you do not
already have this program you can download it from
ftp://ftp.uu.net/graphics/jpeg
