Remarks

The polygon object is a simple polygon that contains a collection of AnnPoint points, a AnnPen pen and a AnnBrush brush. The polygon can be AnnPolygonObject.Closed or not, and can also have a certain AnnPolygonObject.FillMode. For an illustration of the different fill modes, refer to Illustration of the Polygon Fill Mode for Annotations.

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