Examples

Следующий пример кода предназначен для использования с Windows Forms и требует PaintEventArgse, который является параметром обработчика событий Paint.The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. Код выполняет следующие действия.The code performs the following actions:

  • Создает объект графического контура и добавляет к нему эллипс.Creates a graphics path object and adds an ellipse to it.

  • Создает черное перо.Creates a black pen.

  • Отображает графический контур на экране.Draws the graphics path to the screen.

public:
   void DrawPathEllipse( PaintEventArgs^ e )
   {
      // Create graphics path object and add ellipse.
      GraphicsPath^ graphPath = gcnew GraphicsPath;
      graphPath->AddEllipse( 0, 0, 200, 100 );

      // Create pen.
      Pen^ blackPen = gcnew Pen( Color::Black,3.0f );

      // Draw graphics path to screen.
      e->Graphics->DrawPath( blackPen, graphPath );
   }
public void DrawPathEllipse(PaintEventArgs e)
{
             
    // Create graphics path object and add ellipse.
    GraphicsPath graphPath = new GraphicsPath();
    graphPath.AddEllipse(0, 0, 200, 100);
             
    // Create pen.
    Pen blackPen = new Pen(Color.Black, 3);
             
    // Draw graphics path to screen.
    e.Graphics.DrawPath(blackPen, graphPath);
}
Public Sub DrawPathEllipse(ByVal e As PaintEventArgs)

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

    ' Create pen.
    Dim blackPen As New Pen(Color.Black, 3)

    ' Draw graphics path to screen.
    e.Graphics.DrawPath(blackPen, graphPath)
End Sub

Remarks

Текущее преобразование в графическом контексте применяется к GraphicsPath до его прорисовки.The current transformation in the graphic context is applied to the GraphicsPath before it is drawn.
