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

'Declaration

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

'Usage

Dim instance As SigmaCommand

public sealed class SigmaCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.Core.SigmaCommand()

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

The amount of blur is controlled by specifying the size of the neighborhood.
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.

Runs the SigmaCommand on the Image.
