Strokes.ScaleToRectangle 方法

项目
11/04/2008

根据指定的 Rectangle 结构缩放 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 ScaleToRectangle ( _
    scaleRectangle As Rectangle _
)
用法
Dim instance As Strokes
Dim scaleRectangle As Rectangle

instance.ScaleToRectangle(scaleRectangle)

public void ScaleToRectangle(
    Rectangle scaleRectangle
)

public:
void ScaleToRectangle(
    Rectangle scaleRectangle
)

public void ScaleToRectangle(
    Rectangle scaleRectangle
)

public function ScaleToRectangle(
    scaleRectangle : Rectangle
)

参数

scaleRectangle
类型：System.Drawing.Rectangle
作为缩放 Strokes 集合的依据的 Rectangle 结构（采用墨迹空间 坐标）

备注

对 Strokes 集合进行缩放和转换，让 Stroke 集合的边界框与该矩形匹配。

示例

在此示例中，InkOverlay 对象的 Strokes 集合将进行缩放以适合原始边界框的左半边。首先，通过使用 BoundingBoxMode 枚举的 CurveFit 值确定边界框的边界，并调用 GetBoundingBox 方法获得 Strokes 集合的边框。然后，创建具有原始边框一半宽度的新边框并传递给 ScaleToRectangle 方法。

' 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(BoundingBoxMode.CurveFit)
    Dim halfRectangle As Rectangle = _
            New Rectangle(bounds.Left, bounds.Top, bounds.Width / 2, bounds.Height)
    allStrokes.ScaleToRectangle(halfRectangle)
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(BoundingBoxMode.CurveFit);
    Rectangle halfRectangle = 
        new Rectangle(bounds.Left, bounds.Top, bounds.Width / 2, bounds.Height);
    allStrokes.ScaleToRectangle(halfRectangle);
}
