Set Animation Background Frame

\i g b F byte::anim_loc word::frame

Parameter	Type	Range	Description
anim_loc	byte	0 ... 7	index of the animation control
frame	word	0 ... number of frames - 1	background frame of the animation

Specifies the frame frame as background for the animation engine anim_loc.

When a background frame is assigned to an animation control, every frame is restored to the underlying part of the background before the next one is drawn.
As soon as a background frame is assigned, this frame will be skipped in running animations. It can still be set manually though (refer to Stop Animation and Set Frame Number).
If the background frame doesn't cover the entire animation area, only the part where the areas of the background and the previous frame overlap will be restored.
If the animation was never drawn before, the whole animation area is filled with the background frame before the first frame is drawn.
Restoring frames to background allows an animation to run backwards (refer to Move Animation To Frame), but slows it down a bit.
The background is restored to the assigned background frame when using the commands Erase Animation Image Area or Erase Animation Frame Area as well.
If anim_loc has never been loaded with an animated graphic before, a [NACK] is returned.
Find general information about animated graphics in chapter LCD Graphics Commands.

Response:

[ACK]

Example

\igbF\7\D12
