MedicalViewerWindowLevel Class

Summary

Represents the class that contains the properties for the window level action.

Syntax

C++/CLI

public class MedicalViewerWindowLevel : MedicalViewerCommonActions

            public ref class MedicalViewerWindowLevel : public MedicalViewerCommonActions, System.IDisposable

Remarks

To set the properties of the window level action, call the MedicalViewerBaseCell.SetActionProperties method. To retrieve the properties call the MedicalViewerBaseCell.GetActionProperties method. The mouse controls the actions as follows:

Click and hold the mouse to start the effect. When the assigned mouse button is released the action ends.
Dragging the mouse to the left decreases the center parameter.
Dragging the mouse to the right increases the center parameter.
Dragging the mouse up decreases the width parameter.
Dragging the mouse down increases the width parameter.
