public class ColoredBallsCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration
 
Public Class ColoredBallsCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage
 
Dim instance As ColoredBallsCommand

public sealed class ColoredBallsCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.ColoredBallsCommand()

public ref class ColoredBallsCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

Remarks

This method supports 12- and 16-bit grayscale and 48- and 64-bit color images. Support for 12- and 16-bit grayscale and 48- 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.
