Значение поля

Тип: System.Int32
The maximum value that the tablet reports for this property.

Заметки

For example, a tablet reporting x-values from 0 to 9000 has a logical maximum of 9000.

Примеры

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.

Try
    For Each S As Stroke In mInkOverlay.Selection
        ' get the PacketProperty.NormalPressure metrics for the stroke
        Dim metrics As TabletPropertyMetrics = S.GetPacketDescriptionPropertyMetrics(PacketProperty.NormalPressure)
        ' get the starting point
        Dim startPt As Integer = S.PacketCount / 2
        ' get the NormalPressure values starting at startPt
        Dim npValues() As Integer = S.GetPacketValuesByProperty(PacketProperty.NormalPressure, startPt)
        ' set the NormalPressure values to max
        For k As Integer = 0 To npValues.Length - 1
            npValues(k) = metrics.Maximum
        Next
        ' set the NormalPressure values starting at startPt
        S.SetPacketValuesByProperty(PacketProperty.NormalPressure, startPt, npValues)
    Next

Catch ex As ArgumentException
    ' This exception will be raised if PacketProperty.NormalPressure is not supported
    ' This will be the case if creating strokes with a mouse
End Try

try
{
    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);
    }
}

    // This exception will be raised if PacketProperty.NormalPressure is not supported
