CloudsCommand Class

Summary

Applies cloud effects to a bitmap. Imaging Pro and above toolkits include this commant.

Syntax

WinRT C#

C++

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

Public Class CloudsCommand  
   Inherits Leadtools.Imageprocessing.Leadtools.ImageProcessing.RasterCommand 
   Implements Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

public sealed class CloudsCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.CloudsCommand()

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

Remarks

This method can process the entire image or a region of the image. If the image has a region, the effect is applied only to the region.
The Seed property changes the starting point for the cloud shape randomization process. The same seed value results in clouds of the same shape.
This method supports 12-bit and 16-bit grayscale and 48-bit and 64-bit color images. Only the Document/Medical toolkits support for 12-bit and 16-bit grayscale and 48-bit and 64-bit color images.
This method does not support signed data images.
This command does not support 32-bit grayscale images.

Example

Runs the CloudsCommand on an image.
