Enum FrameDisposalMode

Provides a way to specify how the current frame should be disposed of before rendering the next frame.

public enum FrameDisposalMode

Fields

DoNotDispose = 1: Do not dispose. The current frame is not disposed of, or in other words, not cleared or altered when moving to the next frame. This means that the next frame is drawn over the current frame, and if the next frame contains transparency, the previous frame will be visible through these transparent areas.
RestoreToBackground = 2: Restore to background color. When transitioning to the next frame, the area occupied by the current frame is filled with the background color specified in the image metadata. This effectively erases the current frame by replacing it with the background color before the next frame is displayed.
RestoreToPrevious = 3: Restore to previous. This method restores the area affected by the current frame to what it was before the current frame was displayed. It essentially "undoes" the current frame, reverting to the state of the image before the frame was displayed, then the next frame is drawn. This is useful for animations where only a small part of the image changes from frame to frame.
Unspecified = 0: No disposal specified. The decoder is not required to take any action.
