ham8 al-j al-backdrop
---------------------
Michael Saunby December 1992
Release 1.1
Two JPEG viewers for AGA Amigas (A1200, A4000)
===============================================
Before using either viewer start the public screen program ham8.
Al-j gives a scrollable window display of a JPEG file.
Al-backdrop resizes the screen and loads a JPEG file as a backdrop.
The palette is fixed so a backdrop plus several windows is possible.
Large images eat up lots of chip ram in the windows so load them as backdrops
or use a small screen and scroll them if you run out of ram.
Permission is given for free distribution of these programs providing all
source files are included. The executables and library need not be included.
The programs are not perfect!
-----------------------------
The user assumes the entire risk as to the suitabilty and accuracy of these
programs.

This software is based in part on the work of the Independent JPEG Group.
You will find a copy of the README file which acompanies release 4 of the
Independent JPEG Group's free JPEG software in the source directory. In the
README file are details of how to obtain the source code. Please take
the trouble to get the Independent JPEG Group's source code if you create
another JPEG viewer or converter from the Al-J code.
