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

Object Model

Syntax

C#
Visual Basic
Objective-C
Java
C++

public class MedicalViewerMPRPolygonEventsArgs : System.EventArgs

'Declaration
 
Public Class MedicalViewerMPRPolygonEventsArgs 
   Inherits System.EventArgs

'Usage
 
Dim instance As MedicalViewerMPRPolygonEventsArgs

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.
