Public Shared Function GetCommonDescription (stylusPointDescription As StylusPointDescription, stylusPointDescriptionPreserveInfo As StylusPointDescription) As StylusPointDescription

Parameters

stylusPointDescription: StylusPointDescription

The first StylusPointDescription to intersect.

stylusPointDescriptionPreserveInfo: StylusPointDescription

The second StylusPointDescription to intersect.

Returns

StylusPointDescription

A StylusPointDescription that contains the properties that are present in both of the specified StylusPointDescription objects.

Examples

The following example demonstrates how to find the common StylusPointDescription from two different StylusPointDescription objects.

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

StylusPointDescription1 and stylusPointDescriptionPreserveInfo may have a common property, yet the constraints specified in their respective StylusPointPropertyInfo objects differ. If the constraints differ, the GetCommonDescription method uses the StylusPointPropertyInfo from stylusPointDescriptionPreserveInfo.
