Graphics::DrawBezier Method (Pen, Point, Point, Point, Point)

Draws a Bézier spline defined by four Point structures.

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

public:
void DrawBezier(
	Pen^ pen, 
	Point pt1, 
	Point pt2, 
	Point pt3, 
	Point pt4
)

Parameters

pen
Type: System.Drawing::Pen
Pen structure that determines the color, width, and style of the curve.
pt1
Type: System.Drawing::Point
Point structure that represents the starting point of the curve.
pt2
Type: System.Drawing::Point
Point structure that represents the first control point for the curve.
pt3
Type: System.Drawing::Point
Point structure that represents the second control point for the curve.
pt4
Type: System.Drawing::Point
Point structure that represents the ending point of the curve.

ExceptionCondition
ArgumentNullException

pen is nullptr.

The Bézier curve 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 PaintEventArgs e, 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 DrawBezierPoint( PaintEventArgs^ e )
   {
      // Create pen.
      Pen^ blackPen = gcnew Pen( Color::Black,3.0f );

      // Create points for curve.
      Point start = Point(100,100);
      Point control1 = Point(200,10);
      Point control2 = Point(350,50);
      Point end = Point(500,100);

      // Draw arc to screen.
      e->Graphics->DrawBezier( blackPen, start, control1, control2, end );
   }
