Updates the packet data for the specified stroke.

Namespace: System.Windows.Ink.AnalysisCore
Assembly: IACore (in IACore.dll)

Syntax

'Declaration
Public Sub UpdateStrokeData ( _
    strokeId As Integer, _
    strokePacketData As Integer(), _
    strokePacketDescription As Guid() _
)
'Usage
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 function UpdateStrokeData(
    strokeId : int, 
    strokePacketData : int[], 
    strokePacketDescription : Guid[]
)

Parameters

strokeId
Type: System.Int32

The stroke identifier.

strokePacketData
Type: array<System.Int32[]

An array containing the packet data for the stroke.

strokePacketDescription
Type: array<System.Guid[]

An array containing the packet property identifiers.

Remarks

strokePacketData contains packet data for all of the points in the stroke. strokePacketDescription contains the globally unique identifiers (GUIDs) that describe the types of packet data included for each point in the stroke. For a complete list of available packet properties, see the Microsoft.Ink.PacketProperty class.

This method does not update the ink analyzer's DirtyRegion.

If the specified stroke is not associated with the ink analyzer, this method returns without updating the ink analyzer.

Examples

The following example defines a method, theInkAnalyzerBase_UpdateStrokesCacheBase, that handles the UpdateStrokesCacheBase event of an InkAnalyzerBase. This method retrieves stroke data from an Microsoft.Ink.Ink object, theInk. In practice, if your application is using a Microsoft.Ink.Ink object to store stroke data, your application should use the derived Microsoft.Ink.InkAnalyzer class.
