依指定的量位移這個 Region 座標。

public:
 void Translate(int dx, int dy);

public void Translate (int dx, int dy);

member this.Translate : int * int -> unit

Public Sub Translate (dx As Integer, dy As Integer)

dy

Int32

垂直位移此 Region 的數量。

範例

下列程式代碼範例是專為搭配 Windows Forms 使用而設計，而且需要 PaintEventArgse，這是 Paint 事件處理程式的參數。 程式代碼會執行下列動作：

• 建立矩形，並以藍色將它繪製到螢幕。

• 從矩形建立區域。

• 將翻譯套用至區域。

• 以紅色填滿翻譯的區域，並以紅色將翻譯的區域繪製到畫面。

請注意，紅色矩形會從原始矩形向下和向右移，以藍色顯示。

void TranslateExample( PaintEventArgs^ e )
{
   // Create the first rectangle and draw it to the screen in blue.
   Rectangle regionRect = Rectangle(100,50,100,100);
   e->Graphics->DrawRectangle( Pens::Blue, regionRect );

   // Create a region using the first rectangle.
   System::Drawing::Region^ myRegion = gcnew System::Drawing::Region( regionRect );

   // Apply the translation to the region.
   myRegion->Translate( 150, 100 );

   // Fill the transformed region with red and draw it to the screen in red.
   SolidBrush^ myBrush = gcnew SolidBrush( Color::Red );
   e->Graphics->FillRegion( myBrush, myRegion );
}

public void TranslateExample(PaintEventArgs e)
{
             
    // Create the first rectangle and draw it to the screen in blue.
    Rectangle regionRect = new Rectangle(100, 50, 100, 100);
    e.Graphics.DrawRectangle(Pens.Blue, regionRect);
             
    // Create a region using the first rectangle.
    Region myRegion = new Region(regionRect);
             
    // Apply the translation to the region.
    myRegion.Translate(150, 100);
             
    // Fill the transformed region with red and draw it to the screen in red.
    SolidBrush myBrush = new SolidBrush(Color.Red);
    e.Graphics.FillRegion(myBrush, myRegion);
}

Public Sub TranslateExample(ByVal e As PaintEventArgs)

    ' Create the first rectangle and draw it to the screen in blue.
    Dim regionRect As New Rectangle(100, 50, 100, 100)
    e.Graphics.DrawRectangle(Pens.Blue, regionRect)

    ' Create a region using the first rectangle.
    Dim myRegion As New [Region](regionRect)

    ' Apply the translation to the region.
    myRegion.Translate(150, 100)

    ' Fill the transformed region with red and draw it to the
    ' screen in red.
    Dim myBrush As New SolidBrush(Color.Red)
    e.Graphics.FillRegion(myBrush, myRegion)
End Sub
