示例

下面的代码示例设计用于 Windows 窗体，它需要 PaintEventArgse，这是 Paint 事件处理程序的参数。 该代码执行以下操作：

• 创建纯红色画笔。

• 创建四个点的数组以定义样条。

• 填充屏幕上的曲线。

曲线的默认紧张度为 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 points As Point() = {point1, point2, point3, point4}

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

注解

此方法填充通过数组中每个点的封闭基样线的内部。 如果最后一个点与第一个点不匹配，则会将一个额外的曲线段从最后一个点添加到第一个点以关闭它。

点数组必须至少包含四个 Point 结构。

此方法使用默认的 0.5 紧张。
