Draws a closed cardinal spline defined by an array of System.Drawing.PointF structures.
- pen
- System.Drawing.Pen that determines the color, width, and height of the curve.
- points
- Array of System.Drawing.PointF structures that define the spline.
This method draws a closed cardinal spline that passes through each point in the array. If the last point does not match the first point, an additional curve segment is added from the last point to the first point to close it.
The array of points must contain at least four System.Drawing.PointF structures.
This method uses a default tension of 0.5.
