Leave original image pixels unchanged (RingEffectCommandFlags.NoChange flag is set) or Repeat edge pixels (RingEffectCommandFlags.Repeat flag is set) or Fill the undefined area with color that is stored in the Color property, or the color parameter if you are using the appropriate RingEffectCommand Constructor, if the RingEffectCommandFlags.COlor flag is set).
The determined portion of the ring will always displace the original image pixels.
