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#
VB
WinRT C#
C++
public class ColoredBallsCommand : RasterCommand 
public sealed class ColoredBallsCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand   
function Leadtools.ImageProcessing.SpecialEffects.ColoredBallsCommand() 

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.
