MedicalViewerMPRPolygonEventsArgs Class

Summary

The MedicalViewerMPRPolygonEventsArgs class provides data for the MedicalViewerCell.MPRPolygonCreated event.

Syntax

C#
VB
C++
public class MedicalViewerMPRPolygonEventsArgs : EventArgs 
  
Public Class MedicalViewerMPRPolygonEventsArgs  
   Inherits System.EventArgs 
             
            public ref class MedicalViewerMPRPolygonEventsArgs : public System.EventArgs  
             

Remarks

This class is sent by the event MedicalViewerCell.MPRPolygonCreated. This event is fired when the user is done creating a polygon using the action MedicalViewerActionType.PanoramicPolygon.

The MPR polygon is used to render a panoramic image to be able to show a greater field of view.
