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

'Declaration

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

'Usage

Dim instance As AverageCommand

public sealed class AverageCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTAverageCommand : LTRasterCommand

public class AverageCommand extends RasterCommand

function Leadtools.ImageProcessing.Effects.AverageCommand()

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

You control the amount of blur by specifying the size of the neighborhood that is used for averaging.
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 32-bit grayscale images.
This command supports signed/unsigned data images.

For more information, refer to Removing Noise.

Run the AverageCommand on an image with a neighborhood Dimensions = 3x3 pixels.
