IInkAnalyzer::UpdateStrokesData method
Updates the packet data for the specified strokes.
Syntax
HRESULT UpdateStrokesData(
[in] ULONG ulStrokeIdsCount,
[in] LONG *plStrokeIds,
[in] ULONG ulStrokePacketDescriptionCount,
[in] GUID *pStrokePacketDescriptionGuids,
[in] ULONG *pulPacketDataCountPerStroke,
[in] LONG *plStrokePacketData
);
Parameters
-
ulStrokeIdsCount [in]
-
The number of strokes to update.
-
plStrokeIds [in]
-
An array containing the stroke identifiers.
-
ulStrokePacketDescriptionCount [in]
-
The number of properties in each packet.
-
pStrokePacketDescriptionGuids [in]
-
An array containing the packet property identifiers.
-
pulPacketDataCountPerStroke [in]
-
An array containing the number of packets in each stroke.
-
plStrokePacketData [in]
-
An array containing the packet data for the strokes.
Return value
For a description of the return values, see Classes and Interfaces - Ink Analysis.
Remarks
the plStrokePacketData parameter contains packet data for all of the strokes. The pStrokePacketDescriptionGuids parameter contains the globally unique identifiers (GUIDs) that describe the types of packet data included for each point in each stroke. For a complete list of available packet properties, see PacketPropertyGuids Constants.
Only strokes with the same packet descriptions can be updated in a single call to IInkAnalyzer::UpdateStrokesData Method.
This method does not update the ink analyzer's dirty region (see IInkAnalyzer::GetDirtyRegion Method).
If a specified stroke is not associated with the IInkAnalyzer, this method ignores the identifier.
If none of the specified strokes identify a stroke associated with the IInkAnalyzer, this method returns without updating the IInkAnalyzer.
This method returns an error code when plStrokeIds is NULL.
