Definisi

Ruang nama:

System.Windows.Ink

Rakitan:

PresentationCore.dll

Mengembalikan poin stylus yang Stroke digunakan saat FitToCurve adalah true.

public:
 System::Windows::Input::StylusPointCollection ^ GetBezierStylusPoints();

public System.Windows.Input.StylusPointCollection GetBezierStylusPoints ();

member this.GetBezierStylusPoints : unit -> System.Windows.Input.StylusPointCollection

Public Function GetBezierStylusPoints () As StylusPointCollection

Mengembalikan

StylusPointCollection

StylusPointCollection yang berisi titik stylus di sepanjang tulang Stroke belakang ketika FitToCurve adalah true.

Contoh

Contoh berikut menunjukkan cara menggambar lingkaran di setiap StylusPointStroke. FitToCurve Jika properti diatur ke true, GetBezierStylusPoints digunakan untuk mendapatkan titik stylus. Jika tidak, StylusPoints properti digunakan.

protected override void DrawCore(DrawingContext context, DrawingAttributes overrides)
{
    // Draw the stroke. Calling base.DrawCore accomplishes the same thing.
    Geometry geometry = GetGeometry(overrides);
    context.DrawGeometry(new SolidColorBrush(overrides.Color), null, geometry);

    StylusPointCollection points;

    // Get the stylus points used to draw the stroke.  The points used depends on
    // the value of FitToCurve.
    if (this.DrawingAttributes.FitToCurve)
    {
        points = this.GetBezierStylusPoints();
    }
    else
    {
        points = this.StylusPoints;
    }

    // Draw a circle at each stylus point.
    foreach (StylusPoint p in points)
    {
        context.DrawEllipse(null, new Pen(Brushes.Black, 1), (Point)p, 5, 5);
    }
}

Protected Overrides Sub DrawCore(ByVal context As DrawingContext, _
        ByVal overridedAttributes As DrawingAttributes)

    ' Draw the stroke. Calling base.DrawCore accomplishes the same thing.
    Dim geometry As Geometry = GetGeometry(overridedAttributes)
    context.DrawGeometry(New SolidColorBrush(overridedAttributes.Color), Nothing, geometry)

    Dim points As StylusPointCollection

    ' Get the stylus points used to draw the stroke.  The points used depends on
    ' the value of FitToCurve.
    If Me.DrawingAttributes.FitToCurve Then
        points = Me.GetBezierStylusPoints()
    Else
        points = Me.StylusPoints
    End If

    ' Draw a circle at each stylus point.
    Dim p As StylusPoint
    For Each p In points
        context.DrawEllipse(Nothing, New Pen(Brushes.Black, 1), CType(p, Point), 5, 5)
    Next p

End Sub

Keterangan

Metode GetBezierStylusPoints mengembalikan yang baru StylusPointCollection yang berisi titik stylus yang Stroke digunakan saat FitToCurve properti pada DrawingAttributes properti diatur ke true. Untuk mendapatkan titik stylus yang digunakan saat FitToCurve diatur ke false, gunakan StylusPoints properti .
