Examples

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 solid red brush.

• Creates an array of four points to define a spline.

• Fills the curve on the screen.

The curve has a default tension of 0.5.

public:
   void FillClosedCurvePoint( PaintEventArgs^ e )
   {
      // Create solid brush.
      SolidBrush^ redBrush = gcnew SolidBrush( Color::Red );

      //Create array of points for curve.
      Point point1 = Point(100,100);
      Point point2 = Point(200,50);
      Point point3 = Point(250,200);
      Point point4 = Point(50,150);
      array<Point>^ points = {point1,point2,point3,point4};

      // Fill curve on screen.
      e->Graphics->FillClosedCurve( redBrush, points );
   }

public void FillClosedCurvePoint(PaintEventArgs e)
{
             
    // Create solid brush.
    SolidBrush redBrush = new SolidBrush(Color.Red);
             
    //Create array of points for curve.
    Point point1 = new Point(100, 100);
    Point point2 = new Point(200,  50);
    Point point3 = new Point(250, 200);
    Point point4 = new Point(50, 150);
    Point[] points = {point1, point2, point3, point4};
             
    // Fill curve on screen.
    e.Graphics.FillClosedCurve(redBrush, points);
}

Public Sub FillClosedCurvePoint(ByVal e As PaintEventArgs)

    ' Create solid brush.
    Dim redBrush As New SolidBrush(Color.Red)

    'Create array of points for curve.
    Dim point1 As New Point(100, 100)
    Dim point2 As New Point(200, 50)
    Dim point3 As New Point(250, 200)
    Dim point4 As New Point(50, 150)
    Dim points As Point() = {point1, point2, point3, point4}

    ' Fill curve on screen.
    e.Graphics.FillClosedCurve(redBrush, points)
End Sub

Remarks

This method fills the interior of a closed cardinal spline that passes through each point in the array. If the last point does not match the first point, an additional curve segment is added from the last point to the first point to close it.

The array of points must contain at least four Point structures.

This method uses a default tension of 0.5.
