範例

下列程式代碼範例的設計目的是要與 Windows Forms 搭配使用，而且需要 PaintEventArgsePaint 事件物件。 程式代碼會執行下列動作：

• 在套用縮放轉換之前，先將矩形繪製到畫面上（藍色矩形）。

• 建立矩陣，並在 x 軸中將矩陣縮放為 3，並在 Y 軸中縮放 2。

• 將此矩陣轉換套用至矩形。

• 將轉換的矩形繪製到畫面（紅色矩形）。

請注意，紅色矩形的縮放比例為 X 軸中的 3，而 Y 軸為 2，包括矩形左上角（矩形的起點）。

      // Draw the rectangle to the screen before applying the
      // transform.
      e->Graphics->DrawRectangle( myPen, 50, 50, 100, 100 );

      // Create a matrix and scale it.
      Matrix^ myMatrix = gcnew Matrix;
      myMatrix->Scale( 3, 2, MatrixOrder::Append );

      // Draw the rectangle to the screen again after applying the
      // transform.
