Remarks

The point object is a single point. This object works in two ways: If the value of ShowPicture is true; this object will draw the picture in Picture with CenterPoint as the center point. AnnObjectBase.Stroke, AnnObjectBase.Fill and Radius will be ignored. If ShowPicture is false; this object will draw an ellipse using AnnObjectBase.Stroke, AnnObjectBase.Fill and Radius around CenterPoint.

This class implements the IAnnPictureObject interface and accesses the IAnnPictureObject.Picture property that handles the picture associated with the annotation object.
