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 Pen。 
- 设置笔的转换矩阵,以在 x 轴方向缩放 2 次。 
- 将线条绘制到屏幕。 
- 将转换矩阵重置为标识。 
- 将第二行绘制到屏幕。

   void ResetTransform_Example( PaintEventArgs^ e )

      // Create a Pen object.
      Pen^ myPen = gcnew Pen( Color::Black,3.0f );
      
      // Scale the transformation matrix of myPen.
      myPen->ScaleTransform( 2, 1 );
      
      // Draw a line with myPen.
      e->Graphics->DrawLine( myPen, 10, 0, 10, 200 );
      
      // Reset the transformation matrix of myPen to identity.
      myPen->ResetTransform();
