'Declaration

Public Class AddNoiseCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage

Dim instance As AddNoiseCommand

public sealed class AddNoiseCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTAddNoiseCommand : LTRasterCommand

public class AddNoiseCommand extends RasterCommand

function Leadtools.ImageProcessing.Effects.AddNoiseCommand()

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

This command 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 command does not support signed data images.
This command does not support 32-bit grayscale images.

For more information, refer to Applying Artistic Effects.

Run the AddNoiseCommand to add red noise to the image.
