InkAnalyzerBase.UpdateStrokeData 方法

项目
11/04/2008

更新指定笔画的数据包数据。

命名空间： System.Windows.Ink.AnalysisCore
程序集： IACore（在 IACore.dll 中）

语法

声明
Public Sub UpdateStrokeData ( _
    strokeId As Integer, _
    strokePacketData As Integer(), _
    strokePacketDescription As Guid() _
)
用法
Dim instance As InkAnalyzerBase
Dim strokeId As Integer
Dim strokePacketData As Integer()
Dim strokePacketDescription As Guid()

instance.UpdateStrokeData(strokeId, strokePacketData, _
    strokePacketDescription)

public void UpdateStrokeData(
    int strokeId,
    int[] strokePacketData,
    Guid[] strokePacketDescription
)

public:
void UpdateStrokeData(
    int strokeId, 
    array<int>^ strokePacketData, 
    array<Guid>^ strokePacketDescription
)

public void UpdateStrokeData(
    int strokeId,
    int[] strokePacketData,
    Guid[] strokePacketDescription
)

public function UpdateStrokeData(
    strokeId : int, 
    strokePacketData : int[], 
    strokePacketDescription : Guid[]
)

参数

strokeId
类型：System.Int32
笔画标识符。

strokePacketData
类型：array<System.Int32[]
包含笔画数据包数据的数组。

strokePacketDescription
类型：array<System.Guid[]
包含数据包属性标识符的数组。

备注

strokePacketData 包含笔画中所有点的数据包数据。strokePacketDescription 包含用于描述笔画中每个点所包含的数据包数据类型的全局唯一标识符 (GUID)。有关可用数据包属性的完整列表，请参见 Microsoft.Ink.PacketProperty 类。

此方法不更新墨迹分析器的 DirtyRegion。

如果指定笔画不与墨迹分析器相关联，则此方法返回但不更新墨迹分析器。

示例

下面的示例定义 theInkAnalyzerBase_UpdateStrokesCacheBase 方法，该方法处理 InkAnalyzerBase 的 UpdateStrokesCacheBase 事件。此方法从 Microsoft.Ink.Ink 对象 theInk 中检索笔画数据。实际上，如果应用程序要使用 Microsoft.Ink.Ink 对象存储笔画数据，则应用程序应使用派生的 Microsoft.Ink.InkAnalyzer 类。
