public:
 void Scale(float scaleX, float scaleY);
public void Scale (float scaleX, float scaleY);
member this.Scale : single * single -> unit
Public Sub Scale (scaleX As Single, scaleY As Single)

參數

scaleX
Single

用來在 X 軸方向縮放這個 Matrix 的值。

scaleY
Single

用來在 Y 軸方向縮放這個 Matrix 的值。

public:
 void Scale(float scaleX, float scaleY, System::Drawing::Drawing2D::MatrixOrder order);
public void Scale (float scaleX, float scaleY, System.Drawing.Drawing2D.MatrixOrder order);
member this.Scale : single * single * System.Drawing.Drawing2D.MatrixOrder -> unit
Public Sub Scale (scaleX As Single, scaleY As Single, order As MatrixOrder)

參數

scaleX
Single

用來在 X 軸方向縮放這個 Matrix 的值。

scaleY
Single

用來在 Y 軸方向縮放這個 Matrix 的值。

order
MatrixOrder

MatrixOrder,指定將縮放向量套用至這個 Matrix 的順序 (附加或預先規劃)。

範例

下列程式碼範例是設計來搭配Windows Forms使用,而且需要 PaintEventArgse 事件 Paint 物件。 此程式碼會執行下列動作:

  • 在套用縮放轉換之前,將矩形繪製到畫面, (藍色矩形) 。

  • 建立矩陣,並在 X 軸中將它縮放為 3,並在 Y 軸中縮放 2。

  • 將此矩陣轉換套用至矩形。

  • 將已轉換的矩形繪製到畫面 (紅色矩形) 。

請注意,紅色矩形已依 X 軸的 3 係數和 2 在 Y 軸縮放,包括矩形的左上角 (矩形的起點) 。
