Draws a series of Bezier splines from an array of Point structures.
Namespace:

Assembly:

public void DrawBeziers( Pen pen, Point[] points )
Type: Aurigma.GraphicsMill.Drawing.Pen
A Pen that determines the color, width, and style of the curve.Type: System.Drawing.Point[]
An array of Point structures that represent the points that determine the curve. The number of points in the array should be a multiple of 3 plus 1, such as 4, 7, or 10.A Bezier spline is defined with four points: first and last point specify beginning and end of the curve, second and third points specify so-called control points. The control points act as magnets, pulling the curve in certain directions to influence the way the Bezier spline bends.
The end point of each spline is a start point for the next one. So the points array should have at least 4 points and + 3 points for each extra spline.
