Tablet.GetPropertyMetrics Method

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 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
