The Desktop Picture NDA : "Mural"
-----------------------
by George Grant

Copyright (C)1989 by George Grant  --  version 1.3 : 8/11/89


About the NDA...
----------------
  Yes, here it is! That luxury those Mac owners have had for too long...
Mural replaces the normal "periwinkle-blue" desktop with a picture
of anything you want. This NDA was programmed in TML Pascal (hooray for
TML Systems!), and is only 2 pages of source code. Although it was
programmed under GS/OS System Disk 5.0, there is no reason why it should
not be able to run under System 4.0; it uses no routines specific to
the new System Disk.

How To Use it...
----------------
  Well! Look at the new version number! We've come a long way in a
day! Especially a weekday! We're now up to version 1.3, which means
that Mural has gotten even BETTER! The random Apple Menu crash
bug has been fixed, and now the Mural NDA is selectable from the
Apple Menu. From the Mural window, you can click in a button to
load in a new picture at any time. This picture can now be type $C0
(packed by DeluxePaint II) OR of type $C1 (uncompressed).
  To have a start-up desktop picture, place an UNCOMPRESSED (type $C1)
picture in your BOOT DISK's "/SYSTEM/DESK.ACCS" folder. Name the
file "Mural.Pic".
  When you boot up into the (System 5.0) Finder, the screen will
momentarily flash the new desktop picture, then return to the
Finder display; the Finder uses special commands for its desktop
icons which make it impossible (well, o.k., pretty hard...) to
put a picture on ITS desktop. Mural is hardy enough to work 
in AppleWorks GS, though!
  Mural will work in either 320 or 640 mode without picture
distortion.

Troubleshooting...
------------------
Q: Hmm. Mural won't read my packed picture file. Why not?
A: When loading a type $C0 (packed) file from the Mural window,
   Mural at this time can only read DeluxePaint-type packed
   pictures, so be sure your file was packed in a DPaint-type
   manner. (For the techies, type $C0, auxtype $02).

Q: Help! Mural says my picture file couldn't be read! What do I do?
A: Are you SURE that the picture you have in the "/Desk.Accs"
   folder is of type $C1? Use the Finder "Icon Info..." item
   to find out.

Q: Hey! Mural says it coudn't find its picture file!
A: Be SURE that you put the "Mural.Pic" file in the "/Desk.Accs" 
   folder of the "/System" folder of your SYSTEM DISK; i.e. the
   DISK YOU _BOOT_ WITH.

Future Versions...

  Here's the planned stuff for the next versions...

v1.0: Fix random Apple Menu crash problem
