Stroke.GetEraseResult Método

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

Parâmetros

Retornos

StrokeCollection

Um StrokeCollection que contém os segmentos do Stroke atual que estão fora dos limites especificados.

Exemplos

O exemplo a seguir remove a tinta que está dentro dos limites especificados.

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)

Comentários

O GetEraseResult método retorna um StrokeCollection que contém traços que representam os segmentos que Stroke estão fora de lassoPoints. GetEraseResult não altera o original Stroke.

O GetClipResult método conecta o primeiro e o último pontos lassoPoints para criar o laço.

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

Parâmetros

Retornos

StrokeCollection

Um StrokeCollection que contém os segmentos do Stroke atual que estão fora dos limites do Rect especificado.

Exemplos

O exemplo a seguir remove a tinta que está dentro dos limites especificados.

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)

Comentários

O GetEraseResult método retorna um StrokeCollection que contém traços que representam os segmentos que Stroke estão fora de bounds. GetEraseResult não altera o original Stroke.

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

Parâmetros

Retornos

StrokeCollection

Um StrokeCollection que contém cópias dos segmentos do Stroke atual após ele ser apresentado pelo caminho especificado.

Exemplos

O exemplo a seguir demonstra como apagar a tinta que cruza um caminho especificado.

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)

Comentários

O GetEraseResult método usa eraserShape para testar o traço e eraserPath retorna um StrokeCollection que representa segmentos dissecados. GetEraseResult não altera o original Stroke.
