GraphicsPath.AddClosedCurve Method (PointF)
Adds a closed curve to this path. A cardinal spline curve is used because the curve travels through each of the points in the array.
Assembly: System.Drawing (in System.Drawing.dll)
The user must keep the original points if they are needed. The original points are converted to cubic Bézier control points internally, therefore there is no mechanism for returning the original points. If the first point and the last point in the points array are not the same point, the curve is closed by connecting these two points. The tension value cannot be set for this method, and defaults to a value equivalent to 0.5.
