ColoredBallsCommand Class

Summary

Throws colored balls over the image. The resulting color of the ball is a combination of ball color and the color of the pixel where it has fallen with certain opacity. Various parameters control the color and appearance of the balls.

Syntax

C++

public class ColoredBallsCommand : RasterCommand

  
Public Class ColoredBallsCommand  
   Inherits RasterCommand

public ref class ColoredBallsCommand : public RasterCommand

Remarks

This method supports 12-bit and 16-bit grayscale and 48-bit and 64-bit color images. Support for 12-bit and 16-bit grayscale and 48-bit and 64-bit color images is available only in the Document/Medical toolkits.
If the image has a region, this method works only on the region. If the image does not have a region, this method works on the entire image.
This method does not support signed data images.
This command does not support 32-bit grayscale images.

Example

Run the ColoredBallsCommand on an image.
