Before a frame is drawn, you can define how the previous frame will be cleared.
The following clear methods are supported:
|Undefined||Nothing will be done to the background before displaying the next image.|
|Leave||Leave the previous graphic image as the next is drawn.|
|Restore background||Redraw the original background color as the current image is drawn.|
|Restore previous||Redraw the previous image as the current image is drawn.|
This setting can be applied to multiple frames at once.
