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。 此程式碼會執行下列動作：

• 建立一條路徑，並在路徑上加入一個矩形。

• 會用黑色把那個矩形畫到螢幕上。

• 用透視扭曲來扭曲路徑。

• 將扭曲的矩形（路徑）以紅色繪製到螢幕。

      GraphicsPath^ myPath = gcnew GraphicsPath;
      RectangleF srcRect = RectangleF(0,0,100,200);
      myPath->AddRectangle( srcRect );

      // Draw the source path (rectangle)to the screen.
      e->Graphics->DrawPath( Pens::Black, myPath );

      // Create a destination for the warped rectangle.
      PointF point1 = PointF(200,200);
      PointF point2 = PointF(400,250);

備註

對於 destPoints，陣列可以包含三個或四個元素。 若陣列包含三個元素，平行四邊形右下角由前三個點所隱含。
