中心点を基準として Strokes コレクションを回転します。

名前空間 : Microsoft.Ink
アセンブリ : Microsoft.Ink (Microsoft.Ink.dll 内)

構文

'宣言
Public Sub Rotate ( _
    degrees As Single, _
    point As Point _
)
'使用
Dim instance As Strokes
Dim degrees As Single
Dim point As Point

instance.Rotate(degrees, point)

public void Rotate(
    float degrees,
    Point point
)

public:
void Rotate(
    float degrees, 
    Point point
)

public void Rotate(
    float degrees,
    Point point
)

public function Rotate(
    degrees : float, 
    point : Point
)

パラメータ

degrees
型 : System.Single
時計回りに回転する角度。

point
型 : System.Drawing.Point
インク空間座標において、回転の基準とするポイント。

例

この例では、InkOverlay オブジェクトの Strokes コレクションが時計回りに 60 度回転されます。回転は、Strokes コレクションの境界ボックスの中心を基準に行われます。

' Access to the Strokes property returns a copy of the Strokes object.
' This copy must be implicitly (via using statement) or explicitly
' disposed of in order to avoid a memory leak.
Using allStrokes As Strokes = mInkOverlay.Ink.Strokes
    Dim bounds As Rectangle = allStrokes.GetBoundingBox()
    ' create a point at the center of bounding box
    Dim center As Point = New Point(bounds.Left + (bounds.Width / 2), bounds.Top + (bounds.Height / 2))
    allStrokes.Rotate(60.0F, center)
End Using

// Access to the Strokes property returns a copy of the Strokes object.
// This copy must be implicitly (via using statement) or explicitly
// disposed of in order to avoid a memory leak.
using (Strokes allStrokes = mInkOverlay.Ink.Strokes)
{
    Rectangle bounds = allStrokes.GetBoundingBox();
    // create a point at the center of bounding box
    Point center = new Point(bounds.Left+(bounds.Width/2), bounds.Top+(bounds.Height/2));
    allStrokes.Rotate(60.0f, center);
