MedicalViewerCobbAngle Class

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.

Object Model

Syntax

C#
Visual Basic
Objective-C
Java
C++

public class MedicalViewerCobbAngle

'Declaration
 
Public Class MedicalViewerCobbAngle

'Usage
 
Dim instance As 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.
