Medical3DWindowLevelEventArgs Class

Summary
The Medical3DWindowLevelEventArgs class provides data about the WindowLevelChanged event.
Syntax
C#
C++/CLI
public class Medical3DWindowLevelEventArgs : EventArgs 
public ref class Medical3DWindowLevelEventArgs : public System.EventArgs  
Remarks

Window-leveling allows the brightness and contrast of the 3D object to be adjusted. Various algorithms result in different brightness and contrast for the 3D object. For more information, refer to Medical3DObject.WindowLevelProperties.

Adjust window-leveling using the mouse by enabling the Action. To enable window-leveling, use the AddAction method to add the window level action to the Medical3DControl. Then use the SetAction method to associate the window level action with a mouse button.
