Short: IFF ANIM3/5/7 player, supports CyberGraphX

CYBERANIM IFF/ANIM-format Animation Player v1.0 8 Sep 1996
-----------------------------------------------
This program plays IFF ANIM3/5/7-format bitmapped animation files on
any Amiga+GfxCard with OS3.0 or higher and CyberGraphX V2.18 (40.89)
or higher.
In general, it can play any IFF ANIM3/5/7-format animation in a
different screen mode than intended. It is most useful for playing
AGA 256-colour animations on an ECS Amiga with a gfx-card.
The files in this archive may be distributed anywhere provided they are
unmodified and are not sold for profit.

FEATURES:
---------
Uses an Intuition-friendly Screen. You can flip it to the back with
left-Amiga M, while an animation is playing.
Plays either from ram or directly from disk. Falls back to disk play
when not enough ram is available.
Uses an ASL ScreenMode requester.
Supports Extra-Half-Brite (EHB) animations.
Uses a double-height Screen and ScrollVPort() for double-buffering.
Dragging the Screen up and down (left Amiga left mouse button drag)
will reveal both buffers. Note that this method of double-buffering
mightn't work properly before CyberGraphX V2.18 (40.89). Make sure
you have an up to date version of CyberGraphX or you might see only
every second frame.
Renders to fastmem bitplanes, then blits to the Screen using gfx-card
friendly BltBitMapRastPort(). Blits only the parts of each frame that
changed since the previous frame (actually the 2nd-previous frame).
Runs from either icon or shell. Uses icon tooltypes for options (i.e,
WorkBench Icons/Information... menu item).
Playback speed can be controlled with F-keys.
Source code is included, so if something doesn't work you can fix it.
LIMITATIONS:
------------
Does not support HAM or HAM8 in CyberGraphX modes (although they can
be played in the wrong colours).
Double-buffering is not synchronised with the gfx-card video beam in
CyberGraphX modes. There seems to be no supported way of doing this.
My experiments seem to indicate that WaitTOF() still uses the native
chipset vblank, which is out of step with the gfx-card vblank. If
flicker is a problem, as it is with certain animations on my GVP
Spectrum gfx-card, try using the WAITTOF option or try "setenv
CYBERGRAPHICS/CPUP2C 1". However these will slow down animations and
other graphics operations.
Palette changes are not synchronised with the CyberGraphX video beam
either, so animations with palette changes may flicker too.
CYBERANIM doesn't cope with all anim7-format files, e.g, if the first
frame is a DLTA chunk instead of a BODY chunk.
When looping an animation, CYBERANIM assumes the last 2 frames restore
the first 2 frames exactly. If that is not the case, the animation
may jitter and/or garbage may appear on the display the 2nd and
subsequent times around.
CYBERANIM does not support masks, colour ranges or sound. CYBERANIM
ignores unrecognised IFF chunks.
Some corrupt anim files may crash CYBERANIM (although most won't).
