JPEG/JFIF Datatype Handler
--------------------------

Here is another datatype to make your datatype programs much more useful!
As the title suggests this handler will decode JPEG/JFIF files for you, 
through any datatype compatible program and display them at a maximum
of 24 bits depth.

To use this program you must have version 1.4 of Jon Watte's DataTypes
library (available from ftp.be.com in the contrib/libraries directory)
installed on your system.  Just drop JPEGHandler into /boot/DataTypes
and it will be automatically be recognized by datatype aware programs.

This software is based in part on the work of the Independent JPEG Group,
and I am very grateful to Thomas Lane and associates for making the JPEG
format a lot less confusing.

History
-------

1.00 - Inital Release
1.01 - Removed DATAMakeView() code, now only outputs 32bit data (previously
       the datatype rendered to the depth of active workspace) thanks to
       Jeremy Moskovish.  Compiled with CodeWarrior 1.1
1.50 - Added DATABitmap -> JPEG saver method.  This accepts either 8bit or 
	   32bit data. Recompiled with CodeWarrior 1.1.1
	   Implemented a preference view (see below).  The JPEGHandler can now be
	   run like an application to allow you to edit the settings.
	   
Preference View
---------------

New for version 1.5 is a preferences view, within this view you can change
the compression quality of encoding JPEGs.  As an note to programmers, you
can fully resize the view as required.
