Parameters

origin

Represents the coordinates (in pixels) for the origin of the rings. Only positive values are accepted.

radius

If the RingEffectCommandFlags.Radius flag is set, this is the width of each ring, in pixels. If the RingEffectCommandFlags.MaxRadius flag is set, this is the maximum radius, in pixels. In this latter case, the width of each ring is equal to ((radius) / (ringCount + 1)). Only positive values are accepted.

ringCount

Number of rings. Only positive values are accepted.

randomize

The starting point for the randomization process. Valid range is 0-500. If 0, the command will pick the starting point. If > 0, this value will be the starting point. Only positive values are accepted.

color

Color used to fill the undefined area. This parameter is used only if the RingEffectCommandFlags.Color flag is set.

angle

The rotation angle value for each ring compared to the inner ring, in hundredths of degrees. This parameter is used only if the RingEffectCommandFlags.FixedAngle flag. The range of the acceptable values is from -18000 to 18000. This value is divided internally by 100.

flags

Flags which control the behavior of this command. These flags can be OR-ed together, unless otherwise specified.

Run the RingEffectCommand on an image.

The maximum ring radius is equal to half of the image's width. Draw 10 rings, fill the undefined areas with the Black color and the shift angle is equal to 1 degrees.
