PPT is a powerful, free image processing package, that boasts with the
following properties:
- Handles both 24 bit truecolor and 8 bit grayscale images with optional
alpha channel.
- Modular design, ie. you can easily add new loaders and filters to the

the same time! No need to wait for another project to be ready!
- Unlimited (except by available memory) buffers!
- Unlimited (except by available disk space) undo!
- User configurable virtual memory (no MMU required)

- Font sensitive and scalable GUI using Jan van den Baard's and Ian
J. Einman's BGUI package (release 41 needed)

Version 4.61 (Sunday, 25-Oct-98 22:46:56)
-----------------------------------------
- Added Contrib-directory to the distribution and made PPT seek modules from there
- Info now shows also which CPUs the current effect/iomod supports
Version 4.62 (Sunday, 08-Nov-98 00:53:30)
-----------------------------------------
- Major changes in localization - now it should even be possible... =)
- Bug fix: AREXX IOMODULEINFO did not handle save formats correctly
- AREXX IOMODULEINFO now returns a new stem item: PREFERREDPOSTFIX
- File requesters now remember their positions (if you use Preferences/Save)
- Bug fix: REXX error messages did not arrive correctly, if loading
failed.
Version 4.63 (Friday, 04-Dec-98 23:18:18)
-----------------------------------------

but failing with error "EOF detected".
Reported by Detlef Wojtaszkiewicz.
Version 4.64 (Saturday, 05-Dec-98 00:04:28)
-------------------------------------------

after a long break... =)
- Implemented new macros for application developers
Version 4.65 (Monday, 07-Dec-98 13:48:59)
-----------------------------------------
- Made toolbar configurable (read/write from preferences file),
but no onscreen config yet. Text only, at the moment.

and opened it again, but now they can be set on the fly.
Version 5.0 (Wednesday, 09-Dec-98 22:23:08)
-------------------------------------------
- THE API HAS CHANGED! You must remove any modules you had, since they
do not work anymore with V5. For the technically minded people:
PPTBase moved from a5 to a3, since it was causing problems with GCC.
It was a stupid idea to begin with, I admit. Should've done my
research better...

------------------------------------------

using CyberGFX.

----------------------------------------
- Added new effect: ColorCount (requested by A. Tolonen)

- Added new function in the support library: CloseProgress().
Version 5.4 (Tuesday, 15-Dec-98 23:29:53)
-----------------------------------------
- Added SetRexxVariable() routine to support library.
- Added PPTX_NoChangeFrame tag, and support for it.
Version 5.5 (Wednesday, 16-Dec-98 22:41:47)

Version 5.6 (Saturday, 19-Dec-98 00:02:39)

a bug in BGUI, but can be circumvented)

- debugging code disabled
I really hope these fix your problems...

- Release C-5

toolbar configuration from the preferences window and saved prefs...
- Bug fix: Huge preview size was not correctly read from preferences file.
Reported by Detlef Wojtaszkiewicz.

-------------------------------------------

pools to malfunction under OSV37. Apparently there are not very many OS2.x people
left anymore, because nobody complained...

-------------------------------------------

vocally ;-)
