How to: Draw a Sequence of Bézier Splines

You can use the DrawBeziers method of the Graphics class to draw a sequence of connected Bézier splines.

The following example draws a curve that consists of two connected Bézier splines. The endpoint of the first Bézier spline is the start point of the second Bézier spline.

The following illustration shows the connected splines along with the seven points.

Bezier Spline

        Point[] p = {
           new Point(10, 100),   // start point of first spline
           new Point(75, 10),    // first control point of first spline
           new Point(80, 50),    // second control point of first spline

           new Point(100, 150),  // endpoint of first spline and 
                                 // start point of second spline

           new Point(125, 80),   // first control point of second spline
           new Point(175, 200),  // second control point of second spline
           new Point(200, 80)};  // endpoint of second spline

        Pen pen = new Pen(Color.Blue);
        e.Graphics.DrawBeziers(pen, p);



The preceding example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler.
