public class AnnClosedCurveObject : AnnPolygonObject, IAnnCurve, IAnnHeader, IAnnObject, IAnnPolygon, IAnnPolyline

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

'Usage
 
Dim instance As AnnClosedCurveObject

public ref class AnnClosedCurveObject : public AnnPolygonObject, IAnnCurve, IAnnHeader, IAnnObject, IAnnPolygon, IAnnPolyline

The closed curve object is a spline curve that contains a collection of System.Windows.Point points, a stroke, a fill and a tension value. The curve can be AnnPolygonObject.IsClosed or not, and can also have a certain AnnPolygonObject.FillRule.

For more information about the closed curve annotation object refer to AnnClosedCurveObject for WPF. For more information about the automated closed curve annotation object, refer to WPF Annotation Objects - Automated Features.

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