RelativeSensitivity Property

Summary

Gets or sets the value that determines whether to use the relative sensitivity feature.

Syntax

C++/CLI

public bool RelativeSensitivity { get; set; }

            public: 
property bool RelativeSensitivity { 
   bool get(); 
   void set (    bool ); 
}

Property Value

true to use the relative sensitivity feature; otherwise, false.

Remarks

The relative sensitivity is a feature that allows the control to adjust the window level action mouse sensitivity based on the image lookup table type. This raises the sensitivity level on the images with relatively large lookup tables in order to achieve smoother results.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.MedicalViewer; 
 
class MedicalViewerForm4 : Form 
{ 
   private MedicalViewer _medicalViewer; 
 
   public MedicalViewerForm4() 
   { 
      RasterCodecs _codecs = new RasterCodecs(); 
      RasterImage _image; 
 
      // Create the medical viewer and adjust the size and the location. 
      _medicalViewer = new MedicalViewer(1, 2); 
      _medicalViewer.Location = new Point(0, 0); 
      _medicalViewer.Size = new Size(this.ClientRectangle.Right, this.ClientRectangle.Bottom); 
 
      // Load an image and then add it to the control. 
      _image = _codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "xa.dcm")); 
      MedicalViewerMultiCell cell = new MedicalViewerMultiCell(_image, true, 1, 1); 
      _medicalViewer.Cells.Add(cell); 
 
      // add some actions that will be used to change the properties of the images inside the control. 
      cell.AddAction(MedicalViewerActionType.WindowLevel);

      cell.AddAction(MedicalViewerActionType.Offset); 
      cell.AddAction(MedicalViewerActionType.Stack); 
 
      // assign the added actions to a mouse button, meaning that when the user clicks and drags the mouse button, the associated action will be activated.
