Note: This is a very primitive port of the ÒdjpegÓ package that was 
developed by the group working on the ÒJPegÓ implementations that 
are supposed to be running across many platforms RSN.  These 
programs are still in the testing phase.  This program is intended to 
be used as a bridge until the final versions become available.

Usage:

Place the application in the same folder where the .jpg file resides.

Launch the application.  When the console dialog appears, at the 
point where the cursor is positioned, enter:

	<file>.jpg <file>.ppm

For example, if I have a file names Òtest.jpgÓ, I would be presented 
with a line like:

	djpeg 

to which I would add to make the complete line:

	djpeg test.jpg test.ppm

Press return or click ÒOKÓ.

IÕve included the ÒREADMEÓ file from the original distribution.  I 
donÕt recommend using the ÒgifÓ creation option, since the color 
selection is abysmal.

The only differences between this program and the distribution 
where changes made to enable the correct compilation options, the 
display of the opening copyright messages, and the ÒWorking...Ó 
implementation.

There are two versions of this program being posted.  ÒdjpegÓ was 
compiled with vanilla 60000 code and no 68881 math co-processor 
support.  It should run on any Mac.  The time required to 
decompress a 32K jpg file into a 497K ppm file was about four 
minutes (not counting the time required for the final write to flush 
the output file.  The timing was done on a Mac IIci.

The Òdpeg.020.68881Ó version has been compiled with both 68020 
and 68881 code generation enabled.  It will only work on Macs that 
have both of these chips.  The timing for the above decompression 
was about 40 seconds.

You will also need to obtain the ÒppmquantÓ and ÒppmtogifÓ 
programs to make proper use of this program.  They should be 
posted within a couple of days.
