Divides the image into the specified number of rings. Each ring is rotated according to a rotation angle. The rotation angle for each ring will be chosen randomly by the command or can be passed to the command. This command is available in the Imaging Pro and above toolkits.
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.
For more information, refer to Applying Artistic Effects.
Run the RingEffectCommand on an image.
