TabletPropertyMetrics Structure

Defines the range and resolution of a packet property.

Namespace:  Microsoft.Ink
Assembly:  Microsoft.Ink (in Microsoft.Ink.dll)

public struct TabletPropertyMetrics

You create a TabletPropertyMetrics structure when you call either the Tablet.GetPropertyMetrics or Stroke.GetPacketDescriptionPropertyMetrics method.

In this example, each selected Stroke object of an InkOverlay object is modified so that each point of the second half of the stroke contains the maxium allowed NormalPressure packet value.

Using the GetPacketValuesByProperty method, the NormalPressure packet values for the second half of the Stroke object are obtained. The values are then set to the maximum allowed (as obtained via the GetPacketDescriptionPropertyMetrics method), and reapplied to the stroke using the SetPacketValuesByProperty method.

    foreach (Stroke S in mInkOverlay.Selection)
        // get the PacketProperty.NormalPressure metrics for the stroke
        TabletPropertyMetrics metrics = S.GetPacketDescriptionPropertyMetrics(PacketProperty.NormalPressure);
        // get the starting point 
        int startPt = S.PacketCount / 2;
        // get the NormalPressure values starting at startPt 
        int[] npValues = S.GetPacketValuesByProperty(PacketProperty.NormalPressure, startPt);
        // set the NormalPressure values to max 
        for (int k = 0; k < npValues.Length; k++)
            npValues[k] = metrics.Maximum;
        // set the NormalPressure values starting at startPt
        S.SetPacketValuesByProperty(PacketProperty.NormalPressure, startPt, npValues);
catch (ArgumentException)
    // This exception will be raised if PacketProperty.NormalPressure is not supported 
    // This will be the case if creating strokes with a mouse
