项目
10/28/2008

围绕中心点旋转 Strokes 集合。

命名空间： Microsoft.Ink
程序集： Microsoft.Ink（在 Microsoft.Ink.dll 中）

语法

声明
Public Sub Rotate ( _
    degrees As Single, _
    point As Point _
)
用法
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
)

参数

degrees
类型：System.Single
顺时针旋转的度数。

point
类型：System.Drawing.Point
围绕其旋转的点，采用墨迹空间 坐标。

示例

在此示例中，InkOverlay 对象的 Strokes 集合顺时针旋转 60 度。旋转围绕 Strokes 集合边界框的中心进行。

' 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);
