Syntax

Java

Objective-C

WinRT C#

C++

public class ShrinkWrapCommand : RasterCommand

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

public sealed class ShrinkWrapCommand : Leadtools.Imageprocessing.Leadtools.ImageProcessing.IRasterCommand

@interface LTShrinkWrapCommand : LTRasterCommand

public class ShrinkWrapCommand extends RasterCommand

function Leadtools.ImageProcessing.Core.ShrinkWrapCommand()

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

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void ShrinkWrapCommandExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   //Load an image 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE3.dcm")); 
 
   //Prepare the command 
   ShrinkWrapCommand command = new ShrinkWrapCommand(); 
 
   command.Threshold = 60; 
   command.Radius = 100; 
   command.Center = new LeadPoint(245, 230); 
   command.Flags = ShrinkWrapFlags.ShrinkRect | ShrinkWrapFlags.RgnSet;  
 
   //Apply  
   command.Run(image); 
}

{ 
   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images";
