public static System.Windows.Input.StylusPointDescription GetCommonDescription (System.Windows.Input.StylusPointDescription stylusPointDescription, System.Windows.Input.StylusPointDescription stylusPointDescriptionPreserveInfo);

static member GetCommonDescription : System.Windows.Input.StylusPointDescription * System.Windows.Input.StylusPointDescription -> System.Windows.Input.StylusPointDescription

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

参数

stylusPointDescription

StylusPointDescription

要相交的第一个 StylusPointDescription。

stylusPointDescriptionPreserveInfo

StylusPointDescription

要相交的第二个 StylusPointDescription。

返回

StylusPointDescription

一个 StylusPointDescription ，它包含两个指定 StylusPointDescription 对象中存在的属性。

示例

以下示例演示如何从两个不同的StylusPointDescription对象中查找公共 StylusPointDescription 的 。

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)

注解

StylusPointDescription1 和 stylusPointDescriptionPreserveInfo 可能具有通用属性，但各自 StylusPointPropertyInfo 对象中指定的约束不同。 如果约束不同，则 GetCommonDescription 方法使用 StylusPointPropertyInfo 中的 stylusPointDescriptionPreserveInfo。
