Not applicable.
Parameters
- pen
Pen that determines the color, width, and style of the curve.
- pt1
PointF structure that represents the starting point of the curve.
- pt2
PointF structure that represents the first control point for the curve.
- pt3
PointF structure that represents the second control point for 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.
private: void DrawBezierPointF( PaintEventArgs^ e ) { // Create pen. Pen^ blackPen = gcnew Pen( Color::Black,3.0f ); // Create points for curve. PointF start = PointF(100.0F,100.0F); PointF control1 = PointF(200.0F,10.0F); PointF control2 = PointF(350.0F,50.0F); PointF end = PointF(500.0F,100.0F); // Draw arc to screen. e->Graphics->DrawBezier( blackPen, start, control1, control2, end ); }
