NAME
FreeJDecoder -- Free the player code for an animation
SYNOPSIS
FreeJDecoder(handle)
D0 A0
VOID FreeJDecoder(APTR handle);
FUNCTION
Frees all resources which were allocated by InitJDecoder().
This is typically called once after playing an animation.
INPUTS
hande - result from InitJDecoder() ONLY!
RESULT
none

NAME
InitJDecoder -- Initialize the player code for a given animation
SYNOPSIS
handle = InitJDecoder(animtype)
D0 D0
APTR InitJDecoder(ULONG animtype);
FUNCTION
Initializes the movie player for a given animation type. This is
typically called once after loading the animation. After playing,
FreeJDecoder() should be called (with the handle this function
returns) to free any resources allocated by this function.
INPUTS
animtype - Bits 0 to 7: Number of bitplanes (1..6)
Bit 16: mode 0 = "Move" (loop), 1 = "EOR" (ping-pong)
RESULT
Non-zero if everything was OK, NULL if no memory or bad animtype.

NAME
ModifyJFrame -- Apply delta data on an animation frame
SYNOPSIS
success = ModifyJFrame( deltas, bitmap, handle )
D0 A0 A1 A2
BOOL ModifyJFrame( APTR, struct BitMap *, APTR );
FUNCTION
Generates a new animation frame by changing the frame before the
currently displayed frame (for double-buffering, as usual).
INPUTS
deltas - pointer to the actual DLTA chunk data
bitmap - BitMap to render into
handle - player handle, from InitJDecoder()
RESULT
Non-zero if everything was OK, FALSE if an error occurred.
