Exemplos

O exemplo a seguir demonstra como localizar o comum StylusPointDescription de dois objetos diferentes StylusPointDescription .

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)

Comentários

StylusPointDescription1 e stylusPointDescriptionPreserveInfo podem ter uma propriedade comum, mas as restrições especificadas em seus respectivos StylusPointPropertyInfo objetos diferem. Se as restrições forem diferentes, o GetCommonDescription método usará o StylusPointPropertyInfo de stylusPointDescriptionPreserveInfo.
