DrawBezier Method (Pen, PointF, PointF, PointF, PointF)

Graphics.DrawBezier Method (Pen, PointF, PointF, PointF, PointF)

 

Draws a Bézier spline defined by four PointF structures.

Namespace:   System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

member DrawBezier : 
        pen:Pen *
        pt1:PointF *
        pt2:PointF *
        pt3:PointF *
        pt4:PointF -> unit

Parameters

pen
Type: System.Drawing.Pen

Pen that determines the color, width, and style of the curve.

pt1
Type: System.Drawing.PointF

PointF structure that represents the starting point of the curve.

pt2
Type: System.Drawing.PointF

PointF structure that represents the first control point for the curve.

pt3
Type: System.Drawing.PointF

PointF structure that represents the second control point for the curve.

pt4
Type: System.Drawing.PointF

PointF structure that represents the ending point of the curve.

Exception Condition
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 start, end, and two control points for the curve.

  • Draws the Bézier curve to the screen.

No code example is currently available or this language may not be supported.
