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.

VB

   // Prepare the command 
   DrawStarCommand command = new DrawStarCommand(new LeadPoint(image.Width / 2, image.Height / 2), 5, image.Width / 2, image.Height / 2, 50, 0, 0, 0, -50, -50, 50, new RasterColor(255, 0, 0), new RasterColor(0, 0, 255), 100, DrawStarCommandFlags.Inside);
