public System.Windows.Input.StylusPointCollection GetStylusPoints (System.Windows.IInputElement relativeTo);
member this.GetStylusPoints : System.Windows.IInputElement -> System.Windows.Input.StylusPointCollection
Public Function GetStylusPoints (relativeTo As IInputElement) As StylusPointCollection

Parameters

relativeTo
IInputElement

The IInputElement to which the (x,y) coordinates in the StylusPointCollection are mapped.

Examples

The following example demonstrates how to get StylusPoint objects from the current StylusDevice.

StylusDevice currentStylus = Stylus.CurrentStylusDevice;
StylusPointDescription description1 =
      new StylusPointDescription(new StylusPointPropertyInfo[]
                    {
                        new StylusPointPropertyInfo(StylusPointProperties.X),
                        new StylusPointPropertyInfo(StylusPointProperties.Y),
                        new StylusPointPropertyInfo(StylusPointProperties.NormalPressure),
                        new StylusPointPropertyInfo(StylusPointProperties.XTiltOrientation),
                        new StylusPointPropertyInfo(StylusPointProperties.YTiltOrientation),
                        new StylusPointPropertyInfo(StylusPointProperties.BarrelButton)
                    });

StylusPointDescription description2 = currentStylus.GetStylusPoints(inkCanvas1).Description;

StylusPointDescription description3 = 
    StylusPointDescription.GetCommonDescription(description1, description2);

StylusPointCollection points = currentStylus.GetStylusPoints(inkCanvas1, description3);

Dim currentStylus As StylusDevice = Stylus.CurrentStylusDevice

Dim description1 As New StylusPointDescription(New StylusPointPropertyInfo() _
    {New StylusPointPropertyInfo(StylusPointProperties.X), _
     New StylusPointPropertyInfo(StylusPointProperties.Y), _
     New StylusPointPropertyInfo(StylusPointProperties.NormalPressure), _
     New StylusPointPropertyInfo(StylusPointProperties.XTiltOrientation), _
     New StylusPointPropertyInfo(StylusPointProperties.YTiltOrientation), _
     New StylusPointPropertyInfo(StylusPointProperties.BarrelButton)})

Dim description2 As StylusPointDescription = currentStylus.GetStylusPoints(inkCanvas1).Description

Dim description3 As StylusPointDescription = _
                        StylusPointDescription.GetCommonDescription(description1, description2)

Dim points As StylusPointCollection = currentStylus.GetStylusPoints(inkCanvas1, description3)

Remarks

subsetToReformatTo must be compatible with the Description property of the StylusPointCollection used by the GetStylusPoints(IInputElement) method. Use the GetCommonDescription method to get a StylusPointDescription before calling the GetStylusPoints(IInputElement, StylusPointDescription) method.
