GraphicsPath.CloseFigure 方法

定義

關閉目前的模型並開始新的模型。 若目前圖包含一連串連通的線條與曲線,該方法透過將一條線從端點連接到起點來封閉迴路。

public:
 void CloseFigure();
public void CloseFigure();
member this.CloseFigure : unit -> unit
Public Sub CloseFigure ()

範例

以下程式碼範例是為 Windows Forms 設計,並需要 PaintEventArgse,一個 OnPaint 事件物件。 該程式碼透過建立新路徑、開始圖形、在圖形上加入兩條相交線條,然後將圖形封閉形成三角形來建立三角形。 接著路徑會被繪製到螢幕上。

private:
   void CloseFigureExample( PaintEventArgs^ e )
   {
      // Create a path consisting of two, open-ended lines and close
      // the lines using CloseFigure.
      GraphicsPath^ myPath = gcnew GraphicsPath;
      myPath->StartFigure();
      myPath->AddLine( Point(10,10), Point(200,10) );
      myPath->AddLine( Point(200,10), Point(200,200) );
      myPath->CloseFigure();

      // Draw the path to the screen.
      e->Graphics->DrawPath( Pens::Black, myPath );
   }
private void CloseFigureExample(PaintEventArgs e)
{
             
    // Create a path consisting of two, open-ended lines and close
             
    // the lines using CloseFigure.
    GraphicsPath myPath = new GraphicsPath();
    myPath.StartFigure();
    myPath.AddLine(new Point(10, 10), new Point(200, 10));
    myPath.AddLine(new Point(200, 10), new Point(200, 200));
    myPath.CloseFigure();
             
    // Draw the path to the screen.
    e.Graphics.DrawPath(Pens.Black, myPath);
}
Public Sub CloseFigureExample(ByVal e As PaintEventArgs)

    ' Create a path consisting of two, open-ended lines and close

    ' the lines using CloseFigure.
    Dim myPath As New GraphicsPath
    myPath.StartFigure()
    myPath.AddLine(New Point(10, 10), New Point(200, 10))
    myPath.AddLine(New Point(200, 10), New Point(200, 200))
    myPath.CloseFigure()

    ' Draw the path to the screen.
    e.Graphics.DrawPath(Pens.Black, myPath)
End Sub
