CLOANTO SOFTWARE UPDATE
FILES BEING UPDATED

- libs/personal_gif_io.library (versions 5.1-5.2 become v. 5.3)
PROGRAMS USING THE FILES

INSTALLATION
- Automatic (requires Installer to be available on system)
NEW FEATURES
This update provides several enhancements and/or corrections over
previous releases:
1) "AnimGIF - Load Anim-Brush" used to require a double-buffering screen
mode to create the animation. This is the standard for proper Amiga
animation, but Personal Paint has always been strong in supporting RTG
animation without double-buffering. This has now been extended to this
script.
2) "AnimGIF - Save Anim-Brush" now allows for the anim-brush transparency
to be set or cleared directly from the user interface of the Rexx
script. Additionally, the timing of the anim-brush frames can be
copied from the timing of the frames in the current animation.
3) On some web browsers, GIF animations using transparency effects would
be displayed differently (e.g. leaving "trails") than with Personal
Paint. This was caused by the lack of a clear specification on the
various frame disposal methods which can be employed for GIF
animations if transparency is used. The update contained in this
archive was designed to offer a better compromise between optimization
and compatibility with different de facto standards.
This archive does not contain, create or modify any GIF code. Only some
animation features are updated. The installation procedure requires the
personal_gif_io.library (version 5.1 or 5.2) to be already installed in the
system. This library (or a newer one) is included with Personal Paint 7.
These are some examples of file sizes of famous GIF animations taken from
the Internet and saved again with Personal Paint 7 and this update:
