Source:

Region.cs

将此 Region 的坐标偏移指定的量。

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

public void Translate (int dx, int dy);

member this.Translate : int * int -> unit

示例

下面的代码示例旨在与 Windows 窗体 一起使用，它需要 PaintEventArgse，它是 事件处理程序的Paint一个参数。 此代码执行以下操作：

• 创建一个矩形并将其绘制到蓝色屏幕。

• 从矩形创建区域。

• 将转换应用于区域。

• 用红色填充已翻译的区域，并将翻译的区域绘制到红色屏幕。

请注意，红色矩形从原始矩形向下向右移动，以蓝色显示。

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
