繞著中心點旋轉 Stroke 物件。

命名空間： Microsoft.Ink
組件： Microsoft.Ink (在 Microsoft.Ink.dll 中)

語法

'宣告
Public Sub Rotate ( _
    degrees As Single, _
    point As Point _
)
'用途
Dim instance As Stroke
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
)

參數

degrees
型別：System.Single
順時針旋轉的度數。

point
型別：System.Drawing.Point
做為旋轉中心的點 (使用「筆墨空間」座標)。

範例

在這個範例中，InkOverlay 物件的每個已選取的 Stroke 都會順時針旋轉 60 度。而且是繞著筆墨控制項的中心旋轉。

Dim inkControl As Control = mInkOverlay.AttachedControl
' get the center of the ink control
Dim centerPt As Point = New Point(inkControl.Width / 2, inkControl.Height / 2)
Using g As Graphics = inkControl.CreateGraphics()
    ' convert center point to ink space coordinates
    mInkOverlay.Renderer.PixelToInkSpace(g, centerPt)
End Using
For Each S As Stroke In mInkOverlay.Selection
    S.Rotate(60.0F, centerPt)
Next

Control inkControl = mInkOverlay.AttachedControl;
// get the center of the ink control
Point centerPt = new Point(inkControl.Width / 2, inkControl.Height / 2);
using (Graphics g = inkControl.CreateGraphics())
{
    // convert center point to ink space coordinates
    mInkOverlay.Renderer.PixelToInkSpace(g, ref centerPt);
}
foreach (Stroke S in mInkOverlay.Selection)
{
    S.Rotate(60.0f, centerPt);
}
