| ArgumentNullException | pen is null. |
The Bézier spline is drawn from the first point to the fourth point. The second and third points are control points that determine the shape of the curve.
The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:
Creates a black pen.
Creates the coordinates of the start, end, and two control points for the curve.
Draws the Bézier curve to the screen.
