Returns the stylus points the Stroke uses when FitToCurve is 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
Returns
A StylusPointCollection that contains the stylus points along the spine of a Stroke when FitToCurve is true
.
Examples
The following example demonstrates how to draw a circle at each StylusPoint of a Stroke. If the FitToCurve property is set to true
, the GetBezierStylusPoints is used to get the stylus points. Otherwise, the StylusPoints property is used.
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
The GetBezierStylusPoints method returns a new StylusPointCollection that contains the stylus points that the Stroke uses when the FitToCurve property on the DrawingAttributes property is set to true
. To get the stylus points that are used when FitToCurve is set to false
, use the StylusPoints property.
