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

'Declaration

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

'Usage

Dim instance As GaussianCommand

public sealed class GaussianCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTGaussianCommand : LTRasterCommand

public class GaussianCommand extends RasterCommand

function Leadtools.ImageProcessing.Effects.GaussianCommand()

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

Each pixel in the image is blurred based on neighborhood pixels. The radius value determines the size of the neighborhood to consider when blurring a pixel. The result is a blurred version of the original image.
The amount of blur is controlled by specifying the size of the neighborhood used for blurring or smoothing. The value of the Radius property determines the size and values of the mask.
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 GaussianCommand on an image and applies the Gaussian filter.
