名稱	Description
GetEraseResult(IEnumerable<Point>)	回傳超出指定範圍的電流 Stroke 區段。
GetEraseResult(Rect)	回傳超出指定矩形的電流 Stroke 區段。
GetEraseResult(IEnumerable<Point>, StylusShape)	經指定路徑切割後，回傳電流Stroke的區段StylusShape。

GetEraseResult(IEnumerable<Point>)

回傳超出指定範圍的電流 Stroke 區段。

public:
 System::Windows::Ink::StrokeCollection ^ GetEraseResult(System::Collections::Generic::IEnumerable<System::Windows::Point> ^ lassoPoints);

public System.Windows.Ink.StrokeCollection GetEraseResult(System.Collections.Generic.IEnumerable<System.Windows.Point> lassoPoints);

member this.GetEraseResult : seq<System.Windows.Point> -> System.Windows.Ink.StrokeCollection

Public Function GetEraseResult (lassoPoints As IEnumerable(Of Point)) As StrokeCollection

參數

lassoPoints

IEnumerable<Point>

一個類型陣列 Point ，指定要刪除的區域。

傳回

StrokeCollection

StrokeCollection A 包含超出指定範圍的電流Stroke段。

範例

以下範例移除了位於指定範圍內的墨水。

Point[] myPoints = new Point[] {
    new Point(100, 100),
    new Point(200, 100),
    new Point(200, 200),
    new Point(100, 200)};

StrokeCollection eraseResults = aStroke.GetEraseResult(myPoints);

// inkCanvas1 is the InkCanvas on which we update the strokes
inkCanvas1.Strokes.Remove(aStroke);
inkCanvas1.Strokes.Add(eraseResults);

Dim myPoints() As System.Windows.Point = _
              {New System.Windows.Point(100, 100), _
               New System.Windows.Point(200, 100), _
               New System.Windows.Point(200, 200), _
               New System.Windows.Point(100, 200)}

Dim eraseResults As StrokeCollection = aStroke.GetEraseResult(myPoints)

' inkCanvas1 is the InkCanvas on which we update the strokes
inkCanvas1.Strokes.Remove(aStroke)
inkCanvas1.Strokes.Add(eraseResults)

備註

該 GetEraseResult 方法回傳包含 StrokeCollection 代表 中 Stroke 位於 lassoPoints之外的段的筆劃。 GetEraseResult 不會改變原始 Stroke的 。

此 GetClipResult 方法將前兩點連接起來 lassoPoints ，形成套索。

GetEraseResult(Rect)

回傳超出指定矩形的電流 Stroke 區段。

public:
 System::Windows::Ink::StrokeCollection ^ GetEraseResult(System::Windows::Rect bounds);

public System.Windows.Ink.StrokeCollection GetEraseResult(System.Windows.Rect bounds);

member this.GetEraseResult : System.Windows.Rect -> System.Windows.Ink.StrokeCollection

Public Function GetEraseResult (bounds As Rect) As StrokeCollection

參數

bounds

Rect

Rect A則指定要刪除的區域。

傳回

StrokeCollection

StrokeCollection A 包含超出指定Stroke範圍的電流Rect區段。

範例

以下範例移除了位於指定範圍內的墨水。

Rect myRect = new Rect(100, 100, 100, 100);

StrokeCollection eraseResults = aStroke.GetEraseResult(myRect);

// inkCanvas1 is the InkCanvas on which we update the strokes
inkCanvas1.Strokes.Remove(aStroke);
inkCanvas1.Strokes.Add(eraseResults);

Dim myRect As New Rect(100, 100, 100, 100)

Dim eraseResults As StrokeCollection = aStroke.GetEraseResult(myRect)

' inkCanvas1 is the InkCanvas on which we update the strokes
inkCanvas1.Strokes.Remove(aStroke)
inkCanvas1.Strokes.Add(eraseResults)

備註

該 GetEraseResult 方法回傳包含 StrokeCollection 代表 中 Stroke 位於 bounds之外的段的筆劃。 GetEraseResult 不會改變原始 Stroke的 。

GetEraseResult(IEnumerable<Point>, StylusShape)

經指定路徑切割後，回傳電流Stroke的區段StylusShape。

public:
 System::Windows::Ink::StrokeCollection ^ GetEraseResult(System::Collections::Generic::IEnumerable<System::Windows::Point> ^ eraserPath, System::Windows::Ink::StylusShape ^ eraserShape);

public System.Windows.Ink.StrokeCollection GetEraseResult(System.Collections.Generic.IEnumerable<System.Windows.Point> eraserPath, System.Windows.Ink.StylusShape eraserShape);

member this.GetEraseResult : seq<System.Windows.Point> * System.Windows.Ink.StylusShape -> System.Windows.Ink.StrokeCollection

Public Function GetEraseResult (eraserPath As IEnumerable(Of Point), eraserShape As StylusShape) As StrokeCollection

參數

eraserPath

IEnumerable<Point>

一個型別 Point 為 的陣列，指定切割 的 Stroke路徑。

eraserShape

StylusShape

StylusShape A則指定橡皮擦的形狀。

傳回

StrokeCollection

StrokeCollection A 包含經指定路徑切割後的電流Stroke段的複製品。

範例

以下範例示範如何擦除與指定路徑相交的墨水。

Point[] myPoints = new Point[] {
    new Point(100, 100),
    new	Point(200, 100),
    new	Point(200, 200),
    new	Point(100, 200)};

EllipseStylusShape myStylus = new EllipseStylusShape(5.0, 5.0, 0.0);

StrokeCollection eraseResults = aStroke.GetEraseResult(myPoints, myStylus);

// inkCanvas1 is the InkCanvas on which we update the strokes
inkCanvas1.Strokes.Remove(aStroke);
inkCanvas1.Strokes.Add(eraseResults);

Dim myPoints() As System.Windows.Point = _
                      {New System.Windows.Point(100, 100), _
                       New System.Windows.Point(200, 100), _
                       New System.Windows.Point(200, 200), _
                       New System.Windows.Point(100, 200)}

Dim myStylus As New EllipseStylusShape(5.0, 5.0, 0.0)

Dim eraseResults As StrokeCollection = aStroke.GetEraseResult(myPoints, myStylus)

' inkCanvas1 is the InkCanvas on which we update the strokes
inkCanvas1.Strokes.Remove(aStroke)
inkCanvas1.Strokes.Add(eraseResults)

備註

此 GetEraseResult 方法使用 eraserShape 敲擊測試筆 eraserPath 觸，回傳代表切割段的 a StrokeCollection 。 GetEraseResult 不會改變原始 Stroke的 。
