Example 







Point structure that contains the star center.
Number of spokes or rays directed inside or outside the star. This parameter only accepts positive values.
Star width. This parameter only accepts positive values.
Star height. This parameter only accepts positive values.
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.
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 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.
Percent of feathering in towards or outward from the spoke center. The valid range is from -100 to 100.
The percent by which to increment or decrement the size of the low part spoke. The valid range is from -100 to 100.
Percent of feathering in towards or outward from the spoke border. The valid range is from -100 to 100.
Transparency, in percent, of the spoke border. The valid range is from -100 to 100.
Lower spoke side color.
Upper spoke side color.
Transparency, in percent, between the star and the affected image. The valid range is from 0 to 100.
Flags that indicate the direction of the rays.
Initializes a new DrawStarCommand class object with explicit parameters.

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.
