Inherits Collection(Of StylusPoint)

StylusPointCollection

Examples

The following example overrides the Stroke.DrawCore method to draw a circle at each StylusPoint comprising a Stroke. If the FitToCurve property is set to true, the GetBezierStylusPoints method returns the stylus points. Otherwise, the StylusPoints property returns the stylus points.

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

Remarks

A Stroke has a StylusPointCollection that contains StylusPoint objects collected from a stylus and digitizer. You can use the StylusPointCollection to customize the Stroke.

Constructors

StylusPointCollection()	Initializes a new instance of the StylusPointCollection class.
StylusPointCollection(IEnumerable<Point>)	Initializes a new instance of the StylusPointCollection class with specified points.

StylusPointCollection(Int32)	Initializes a new instance of the StylusPointCollection class that may initially contain the specified number of StylusPoint objects.
StylusPointCollection(StylusPointDescription, Int32)	Initializes a new instance of the StylusPointCollection class that is the specified size and contains the properties specified in the StylusPointDescription.
StylusPointCollection(StylusPointDescription)	Initializes a new instance of the StylusPointCollection class that contains the properties specified in the StylusPointDescription.

Properties

Count	Gets the number of elements actually contained in the Collection<T>. (Inherited from Collection<T>)
Description	Gets the StylusPointDescription that is associated with the StylusPoint objects in the StylusPointCollection.
Item[Int32]	Gets or sets the element at the specified index. (Inherited from Collection<T>)

SetItem(Int32, T)	Replaces the element at the specified index. (Inherited from Collection<T>)
ToHiMetricArray()	This API supports the product infrastructure and is not intended to be used directly from your code. Converts the property values of the StylusPoint objects into a 32-bit signed integer array.
ToString()	Returns a string that represents the current object. (Inherited from Object)

Operators

Explicit(StylusPointCollection to Point[])
