One powerful feature of this class, is that you can adjust the images while the animation is still running. The following actions can be applied during the animation:

Window level action.
Alpha action.
Offset action.
Scale action.

To load and play an animation, create a cell that contains a multiple-frame image. Once it is created, play or stop the animation using the Animated property.
