Graphics.FillPath(Brush, GraphicsPath) 方法

定义

填充 GraphicsPath的内部。

public:
 void FillPath(System::Drawing::Brush ^ brush, System::Drawing::Drawing2D::GraphicsPath ^ path);
public void FillPath (System.Drawing.Brush brush, System.Drawing.Drawing2D.GraphicsPath path);
member this.FillPath : System.Drawing.Brush * System.Drawing.Drawing2D.GraphicsPath -> unit
Public Sub FillPath (brush As Brush, path As GraphicsPath)

参数

brush
Brush

确定填充特征的 Brush

path
GraphicsPath

表示要填充的路径的 GraphicsPath

例外

brush null

-或-

path null

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。

  • 创建图形路径对象。

  • 向图形路径添加省略号。

  • 填充屏幕上的路径。

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

      // Create graphics path object and add ellipse.
      GraphicsPath^ graphPath = gcnew GraphicsPath;
      graphPath->AddEllipse( 0, 0, 200, 100 );

      // Fill graphics path to screen.
      e->Graphics->FillPath( redBrush, graphPath );
   }
public void FillPathEllipse(PaintEventArgs e)
{
             
    // Create solid brush.
    SolidBrush redBrush = new SolidBrush(Color.Red);
             
    // Create graphics path object and add ellipse.
    GraphicsPath graphPath = new GraphicsPath();
    graphPath.AddEllipse(0, 0, 200, 100);
             
    // Fill graphics path to screen.
    e.Graphics.FillPath(redBrush, graphPath);
}
Public Sub FillPathEllipse(ByVal e As PaintEventArgs)

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

    ' Create graphics path object and add ellipse.
    Dim graphPath As New GraphicsPath
    graphPath.AddEllipse(0, 0, 200, 100)

    ' Fill graphics path to screen.
    e.Graphics.FillPath(redBrush, graphPath)
End Sub

注解

GraphicsPath 由一系列直线和曲线段组成。 如果未关闭由 path 参数表示的路径,则从最后一个点添加到第一个点以关闭路径的其他段。
