MedicalViewerCobbAngle Class

Summary

Represents the class that is used to connect two annotation lines together and displays the angle between them. The angle between them is called the Cobb-Angle.

Syntax
C#
VB
C++
public class MedicalViewerCobbAngle 
  
Public Class MedicalViewerCobbAngle  
            public ref class MedicalViewerCobbAngle  

Remarks

After creating this object, add it to the MedicalViewerSubCell.CobbAngles collection of the MedicalViewerBaseCell control. The two lines must be from the same container.

If any line got removed from the container, this class will be removed from MedicalViewerSubCell.CobbAngles as well.
