Parameters

centerPoint: Point structure that contains the star center.
spoke: Number of spokes or rays directed inside or outside the star. This parameter only accepts positive values.
starWidth: Star width. This parameter only accepts positive values.
starHeight: Star height. This parameter only accepts positive values.
holeSize: The hole size. This value is given as a percent of the whole star from which the rays start or in which they end. The valid range is from 0 to 100.
phase: Angle to shift the star's rays. This value is given in hundredths of a degree (+/-). This can be a number from 0 to 36,000. A positive value will rotate the rays clockwise, while a negative value will rotate the rays counter-clockwise.
angle: Angle to rotate the star. This value is given in hundredths of a degree (+/-). This can be a number from 0 to 36,000. A positive value will rotate the star clockwise, while a negative value will rotate the star counter-clockwise.
distanceOpacity: Percent of feathering in towards or outward from the spoke center. The valid range is from -100 to 100.
spokeDivision: The percent by which to increment or decrement the size of the low part spoke. The valid range is from -100 to 100.
angleOpacity: Percent of feathering in towards or outward from the spoke border. The valid range is from -100 to 100.
borderOpacity: Transparency, in percent, of the spoke border. The valid range is from -100 to 100.
lowerColorFill: Lower spoke side color.
upperColorFill: Upper spoke side color.
opacity: Transparency, in percent, between the star and the affected image. The valid range is from 0 to 100.
flags: Flags that indicate the direction of the rays.

Example

Run the DrawStarCommand on an image.
