FragmentCommand Class

Averages an image with its shifted copies. This method is available in the Raster Pro and above toolkits. This method creates four copies of an image. Each copy is shifted by the offset amount into one of the four directions: top, left, bottom and right. Then the image is averaged with its shifted copies.

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

'Declaration
 
Public Class FragmentCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage
 
Dim instance As FragmentCommand

public sealed class FragmentCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.FragmentCommand()

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

Remarks

This method can process the whole image or a region of the image. If the image has a region, the effect is applied only to the region.
This method 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 method does not support signed data images.
This command does not support 32-bit grayscale images.
