Remarks

The closed curve object is a spline curve that contains a collection of 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.
