Параметры

id
Тип: System.Guid
The Guid identifier from the PacketProperty object that is used to select which packet data is set. Use the PacketDescription property to determine the defined properties for this Stroke object.

packetValues
Тип: array<System.Int32[]
The array of packet data values. The method fails if any of the values in the array exceed the minimum or maximum value of the property. To determine the range of values in the property, call the GetPacketDescriptionPropertyMetrics method.

Возвращаемое значение

Тип: System.Int32
Returns the actual number of packets set.

Заметки

All packets are modified.

This method throws an exception if the packetValues array is the incorrect length.

Примеры

In this example, each selected Stroke object of an InkOverlay object is modified so that the NormalPressure packet always increases or remains constant throughout the points of the stroke.

Using the GetPacketValuesByProperty method, the NormalPressure packet values for the Stroke object are obtained and sorted into ascending order. The sorted values are then reapplied to the stroke using the SetPacketValuesByProperty method.

Try
    For Each S As Stroke In mInkOverlay.Selection
        ' get the NormalPressure values
        Dim npValues() As Integer = S.GetPacketValuesByProperty(PacketProperty.NormalPressure)
        ' sort them
        Array.Sort(npValues)
        ' set the NormalPressure values
        S.SetPacketValuesByProperty(PacketProperty.NormalPressure, 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 NormalPressure values
        int[] npValues = S.GetPacketValuesByProperty(PacketProperty.NormalPressure);
        // sort them
        Array.Sort(npValues);
        // set the NormalPressure values
        S.SetPacketValuesByProperty(PacketProperty.NormalPressure, 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
}
