Тип: Microsoft.Ink.TabletPropertyMetrics
Returns the metrics for a given packet description type.
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);
}
}
catch (ArgumentException)
{
// This exception will be raised if PacketProperty.NormalPressure is not supported
// This will be the case if creating strokes with a mouse
}
