public enum class RasterImageAnimatorState   

class RasterImageAnimatorState(Enum): PreClear = 0 PostClear = 1 PreRender = 2 Render = 3 PostRender = 4 WaitInput = 5 WaitDelay = 6 WaitInputDelay = 7 PreDispose = 8 PostDispose = 9 End = 10

Members

Value Member Description
0 PreClear The initial state of the animation (index = -1). The target image will be cleared to the RasterImage.AnimationBackground color of the current frame on the next call
1 PostClear Indicates that the target image has been cleared
2 PreRender Indicates that the current frame will be rendered to the target image on the next call
3 Render Indicates that a frame has been rendered to the target image
4 PostRender Indicates that a frame is in the midst of being rendered to the target image
5 WaitInput Indicates that the animation engine is waiting for user input before moving on to PreDispose
6 WaitDelay Indicates that the animation engine is waiting for a delayed time before moving on to PreDispose
7 WaitInputDelay Indicates that the animation engine is waiting for user input and a delayed time before moving on to PreDispose
8 PreDispose Indicates that the current frame will be disposed of on the next call
9 PostDispose Indicates that the current frame has been disposed of. The index is incremented after processing this state
10 End Indicates that the animation is past the last frame in the list (index = number of frames or pages). The animator will loop to index = 0 on the next call with the state set to PreRender
