public class AnnPolygonObject : AnnPolylineObject, IAnnHeader, IAnnObject, IAnnPolygon, IAnnPolyline

'Declaration
 
Public Class AnnPolygonObject 
   Inherits AnnPolylineObject
   Implements IAnnHeader, IAnnObject, IAnnPolygon, IAnnPolyline

'Usage
 
Dim instance As AnnPolygonObject

public ref class AnnPolygonObject : public AnnPolylineObject, IAnnHeader, IAnnObject, IAnnPolygon, IAnnPolyline

The polygon object is a simple polygon that contains a collection of System.Windows.Point points, a stroke and a fill. The polygon can be IsClosed or not, and can also have a certain FillRule. For an illustration of the different fill modes, refer to FillRule enumeration.

For more information about the polygon annotation object refer to AnnPolygonObject for WPF. For more information about the automated polygon annotation object, refer to WPF Annotation Objects - Automated Features.

This example creates a new closed polygon object with 4 points.
