Exemplos

O exemplo a seguir demonstra como criar um novo StylusPointCollection que usa um diferente StylusPointDescription.

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)
                    });

// Create a StylusPointCollection that uses description1 as its
// StylusPointDescription.
StylusPointCollection points = new StylusPointCollection(description1);

StylusPointDescription description2 =   
      new StylusPointDescription(new StylusPointPropertyInfo[]
                    {
                        new StylusPointPropertyInfo(StylusPointProperties.X),
                        new StylusPointPropertyInfo(StylusPointProperties.Y),
                        new StylusPointPropertyInfo(StylusPointProperties.NormalPressure),
                        new StylusPointPropertyInfo(StylusPointProperties.ButtonPressure),
                        new StylusPointPropertyInfo(StylusPointProperties.BarrelButton)
                    });

// Find the common StylusPointDescription between description1
// and description2.  Get a StylusPointCollection that uses the
// common StylusPointDescription.
StylusPointDescription common =
    StylusPointDescription.GetCommonDescription(description1, description2);

StylusPointCollection points2 = points.Reformat(common);

Dim description1 As New StylusPointDescription( _
    New StylusPointPropertyInfo() {New StylusPointPropertyInfo(StylusPointProperties.X), _

                                   New StylusPointPropertyInfo(StylusPointProperties.XTiltOrientation), _
                                   New StylusPointPropertyInfo(StylusPointProperties.YTiltOrientation), _
                                   New StylusPointPropertyInfo(StylusPointProperties.BarrelButton)})

' Create a StylusPointCollection that uses description1 as its
' StylusPointDescription.
Dim points As New StylusPointCollection(description1)

Dim description2 As New StylusPointDescription( _
    New StylusPointPropertyInfo() {New StylusPointPropertyInfo(StylusPointProperties.X), _

                                   New StylusPointPropertyInfo(StylusPointProperties.BarrelButton)})

' Find the common StylusPointDescription between description1
' and description2.  Get a StylusPointCollection that uses the

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

Dim points2 As StylusPointCollection = points.Reformat(common)

Comentários

subsetToReformatTo é um StylusPointDescription que descreve um subconjunto de valores pertencentes à Description propriedade . Use o GetCommonDescription método para obter um StylusPointDescription que intersecione o Description do atual StylusPointCollection.

O Reformat método retorna um StylusPointCollection que contém os mesmos StylusPoint objetos que os que pertencem ao atual StylusPointCollection. Os StylusPoint objetos no novo StylusPointCollection usam subsetToReformatTo como o StylusPointDescription.

Observação

Reformat usa as restrições do StylusPointPropertyInfo da Description propriedade , mesmo que as restrições em subsetToReformatTo sejam diferentes. Por exemplo, se subsetToReformatTo usa os valores 0 e 1023 para NormalPressure , enquanto Description usa os valores 0 e 255. Reformat retorna um StylusPointDescription usando os valores, 0 e 255.
