傳回超出指定界限之目前 Stroke 的區段。
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>
Point 型別的陣列,指定要清除的區域。
傳回
StrokeCollection,包含超出指定界限之目前 Stroke 的區段。
範例
下列範例會移除指定界限內的筆跡。
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
方法會 GetEraseResult 傳 StrokeCollection 回 ,其中包含代表 外部 lassoPoints
之 區段的 Stroke 筆劃。 GetEraseResult 不會變更原始 Stroke 的 。
方法 GetClipResult 會連接 中的 lassoPoints
第一個和最後一個點,以建立套索。
適用於
GetEraseResult(Rect)
傳回超出指定矩形之目前 Stroke 的區段。
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
傳回
StrokeCollection,包含超出指定 Stroke 界限之目前 Rect 的區段。
範例
下列範例會移除指定界限內的筆跡。
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
方法會 GetEraseResult 傳 StrokeCollection 回 ,其中包含代表 外部 bounds
之 區段的 Stroke 筆劃。 GetEraseResult 不會變更原始 Stroke 的 。
適用於
GetEraseResult(IEnumerable<Point>, StylusShape)
傳回在由指定路徑使用指定之 Stroke 對其仔細分析後的目前 StylusShape 區段。
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>
- eraserShape
- StylusShape
指定橡皮擦形狀的 StylusShape。
傳回
StrokeCollection,包含由指定路徑對其仔細分析後的目前 Stroke 區段複本。
範例
下列範例示範如何清除與指定路徑交集的筆跡。
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
方法 GetEraseResult 會使用 eraserShape
來沿著點擊測試筆劃 eraserPath
,並傳回 StrokeCollection 代表已剖析區段的 。 GetEraseResult 不會變更原始 Stroke 。
