!ShowTga v1.06 Sep 1996
==========================
This application does what it says - it displays
Targa or PPM files (as output by the excellent PD
Raytracer POV) in the desktop, and will also display
deep sprites on pre-RiscOS 3.5 machines.
An icon is installed on the iconbar. Double-Clicking on
on a Targa (or a PC file,with /TGA or /PPM extension) will
open a window displaying that picture. Deep sprites
must be dragged to the icon or any of its windows
to be loaded.
Closing the window removes the picture from memory.
The icon bar menu allows all the windows to be
closed easily.
Each window has a menu, allowing each picture to be
zoomed independently, and the picture to be saved
as a sprite, in 16M colours in RiscOS 3.5 or better,
or in 256 colours.
Although these files can be displayed using ChangeFSI,
that uses a lot of memory (between 320K and 508K WimpSlot)
- !ShowTga runs in a 32K WimpSlot - and will only
display one picture at a time, while I often want to
compare several versions - hence this program!
The program needs the Toolbox modules - available from
Acorn ftp as part of the C/C++ upgrade1 archive or Argonet ftp.
