Значение поля

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

Заметки

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

Примеры

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

Using the GetPacketValuesByProperty method, the NormalPressure packet values for the first half of the Stroke object are obtained. The values are then set to the minimum 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)
        ' we want to get half of the NormalPressure values
        Dim halfWayPt As Integer = S.PacketCount / 2
        ' get the NormalPressure values for the first half of the packets
        Dim npValues() As Integer = S.GetPacketValuesByProperty(PacketProperty.NormalPressure, 0, halfWayPt)
        ' set the NormalPressure values to min
        For k As Integer = 0 To npValues.Length - 1
            npValues(k) = metrics.Minimum
        Next
        ' set the NormalPressure values for the first half of the packets
        S.SetPacketValuesByProperty(PacketProperty.NormalPressure, 0, halfWayPt, 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);
        // we want to get half of the NormalPressure values
        int halfWayPt = S.PacketCount / 2;
        // get the NormalPressure values for the first half of the packets
        int[] npValues = S.GetPacketValuesByProperty(PacketProperty.NormalPressure, 0, halfWayPt);
        // set the NormalPressure values to min
        for (int k = 0; k < npValues.Length; k++)
        {
            npValues[k] = metrics.Minimum;
        }
        // set the NormalPressure values for the first half of the packets
        S.SetPacketValuesByProperty(PacketProperty.NormalPressure, 0, halfWayPt, npValues);
