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

'Declaration

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

'Usage

Dim instance As ShrinkWrapCommand

public sealed class ShrinkWrapCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTShrinkWrapCommand : LTRasterCommand

public class ShrinkWrapCommand extends RasterCommand

function Leadtools.ImageProcessing.Core.ShrinkWrapCommand()

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

Remarks

The result is applied to the image as a region. This function was designed specifically for CT/MRI images, to segment regions of cancer clusters.

Use MakeRegionEmpty to delete the resulting region.
The radius must not exceed the length of the image diagonal or the class will throw an Invalid Parameters exception and will not execute.
This command does not support 32-bit grayscale images.
This command supports signed/unsigned images.
