Summary

Initializes a new instance of the MedicalViewerWindowLevel class with specified starting color, ending color, width, center, Lookup table type, mouse sensitivity, mouse reset, and cursor.

Syntax

C++/CLI

public MedicalViewerWindowLevel( 
   Color startColor, 
   Color endColor, 
   int width, 
   int center, 
   MedicalViewerLookupTableType lookupTableType, 
   int sensitivity, 
   bool circularMouseMove, 
   Cursor cursor 
)

            public: 
MedicalViewerWindowLevel(  
   Color startColor, 
   Color endColor, 
   int width, 
   int center, 
   MedicalViewerLookupTableType lookupTableType, 
   int sensitivity, 
   bool circularMouseMove, 
   Cursor^ cursor 
)

Parameters

startColor
The color on the low end side of the Lookup table.

endColor
The color on the high end side of the Lookup table.

width
The width of the Lookup table.

center
The center of the Lookup table.

lookupTableType
The type of Lookup table.

sensitivity
Integer value that represents the mouse sensitivity, in percent. The default is 100. This means when the user moves the mouse one pixel, the values (width, center or any other factor) will change by 1 unit. If the value is set to 200 when the mouse is moved 2 pixels the values will change 1 unit.

circularMouseMove
true to make the mouse reset when it reaches the side of the container (when the mouse resets, if it is dragged to one side of the container, it will disappear from that side and reappear on the opposite side of the container); otherwise, false.

cursor
Default cursor for the action.

Example

The following example changes the window level properties and applies it to the first image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.MedicalViewer; 
 
class MedicalViewerForm3 : Form 
{ 
   private MedicalViewer _medicalViewer; 
 
   public MedicalViewerForm3() 
   { 
      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.Scale); 
      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. 
      cell.SetAction(MedicalViewerActionType.WindowLevel, MedicalViewerMouseButtons.Left, MedicalViewerActionFlags.Active); 
      cell.SetAction(MedicalViewerActionType.Offset, MedicalViewerMouseButtons.Right, MedicalViewerActionFlags.Active);

      cell.SetAction(MedicalViewerActionType.Stack, MedicalViewerMouseButtons.Wheel, MedicalViewerActionFlags.Active); 
 
      // adjust some properties of the cell and add some tags. 
      _medicalViewer.Cells[0].SetTag(2, MedicalViewerTagAlignment.TopLeft, MedicalViewerTagType.UserData, "EX. ID 230-36-5448"); 
      _medicalViewer.Cells[0].SetTag(4, MedicalViewerTagAlignment.TopLeft, MedicalViewerTagType.Frame); 
      _medicalViewer.Cells[0].SetTag(6, MedicalViewerTagAlignment.TopLeft, MedicalViewerTagType.Scale); 
      _medicalViewer.Cells[0].SetTag(2, MedicalViewerTagAlignment.BottomLeft, MedicalViewerTagType.WindowLevelData); 
      _medicalViewer.Cells[0].SetTag(1, MedicalViewerTagAlignment.BottomLeft, MedicalViewerTagType.FieldOfView); 
 
      Controls.Add(_medicalViewer); 
      _medicalViewer.Dock = DockStyle.Fill;

   MedicalViewer medicalViewer = myForm.Viewer; 
   MedicalViewerMultiCell cell = (MedicalViewerMultiCell)(medicalViewer.Cells[0]); 
 
   MedicalViewerWindowLevel windowLevel = new MedicalViewerWindowLevel(Color.FromArgb(0, 0, 0), Color.FromArgb(255, 0, 0), 100, 200, MedicalViewerLookupTableType.Exponential, 200, true, Cursors.Cross);
