Source:

GraphicsPath.cs

Adds a cubic Bézier curve to the current figure.

public:
 void AddBezier(System::Drawing::Point pt1, System::Drawing::Point pt2, System::Drawing::Point pt3, System::Drawing::Point pt4);

public void AddBezier (System.Drawing.Point pt1, System.Drawing.Point pt2, System.Drawing.Point pt3, System.Drawing.Point pt4);

member this.AddBezier : System.Drawing.Point * System.Drawing.Point * System.Drawing.Point * System.Drawing.Point -> unit

Public Sub AddBezier (pt1 As Point, pt2 As Point, pt3 As Point, pt4 As Point)

Parameters

pt1

Point

A Point that represents the starting point of the curve.

pt2

Point

A Point that represents the first control point for the curve.

pt3

Point

A Point that represents the second control point for the curve.

pt4

Point

A Point that represents the endpoint of the curve.

Examples

For an example, see AddBezier(Int32, Int32, Int32, Int32, Int32, Int32, Int32, Int32).

Remarks

The cubic curve is constructed from the first point to the fourth point by using the second and third points as control points.

If there is a previous line or curve segment in the figure, a line is added to connect the endpoint of the previous segment to the starting point of the cubic curve.

Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, an OnPaint event object. The code performs the following actions:

• Creates a path.

• Adds a cubic Bézier curve defined by the points (50, 50), (70, 0), (100, 120), and (150, 50) to the path.

• Closes the curve.

• Draws the path to screen.

private:
   void AddBezierExample( PaintEventArgs^ e )
   {
      // Create a new Path.
      GraphicsPath^ myPath = gcnew GraphicsPath;

      // Call AddBezier.
      myPath->StartFigure();
      myPath->AddBezier( 50, 50, 70, 0, 100, 120, 150, 50 );

      // Close the curve.
      myPath->CloseFigure();

      // Draw the path to screen.
      e->Graphics->DrawPath( gcnew Pen( Color::Red,2.0f ), myPath );
   }

private void AddBezierExample(PaintEventArgs e)
{
             
    // Create a new Path.
    GraphicsPath myPath = new GraphicsPath();
             
    // Call AddBezier.
    myPath.StartFigure();
    myPath.AddBezier(50, 50, 70, 0, 100, 120, 150, 50);
             
    // Close the curve.
    myPath.CloseFigure();
             
    // Draw the path to screen.
    e.Graphics.DrawPath(new Pen(Color.Red, 2), myPath);
}

Public Sub AddBezierExample(ByVal e As PaintEventArgs)

    ' Create a new Path.
    Dim myPath As New GraphicsPath

    ' Call AddBezier.
    myPath.StartFigure()
    myPath.AddBezier(50, 50, 70, 0, 100, 120, 150, 50)

    ' Close the curve.
    myPath.CloseFigure()

    ' Draw the path to screen.
    e.Graphics.DrawPath(New Pen(Color.Red, 2), myPath)
End Sub

Remarks

The cubic curve is constructed from the first point to the fourth point by using the second and third points as control points.

If there is a previous line or curve segment in the figure, a line is added to connect the endpoint of the previous segment to the starting point of the cubic curve.
