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

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

'Usage
 
Dim instance As CloudsCommand

public sealed class CloudsCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.CloudsCommand()

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

This method can process the whole image or a region of the image. If the image has a region, the effect is applied only to the region.
The Seed property gives the user the ability to change the shape of the clouds effect by changing the starting point for the clouds randomization process. If the user applies the effect many times with the same value of the Seed property the shape of the clouds will be the same.
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.
This method does not support signed data images.
This command does not support 32-bit grayscale images.
