Tablet.GetPropertyMetrics Method

Returns the metrics data for a known PacketProperty object.

Definition

Visual Basic .NET Public Function GetPropertyMetrics( _
ByVal id As Guid _
) As TabletPropertyMetrics
C# public TabletPropertyMetrics GetPropertyMetrics(
Guid id
);
Managed C++ public: TabletPropertyMetrics* GetPropertyMetrics(
Guid *id
);

Parameters

id System.Guid. The Guid Leave Site identifier for the PacketProperty that you are requesting.

Return Value

Microsoft.Ink.TabletPropertyMetrics. This method returns a TabletPropertyMetrics object for the requested property that is supported by the tablet.

Remarks

The properties for which you retrieve metrics may include the time that a packet was generated or the downward pressure of the pen tip on the tablet surface.

Examples
