속성 값

형식: System.Int32
수신한 in-air 패킷의 수입니다.

설명

in-air 패킷은 Cursor 개체가 태블릿 컨텍스트의 물리적 감지 범위(영역) 안에 들어올 때 발생합니다.

예제

이 예제에서 InkCollectorNewInAirPacketsEventHandler 인스턴스는 InkCollectorNewInAirPacketsEventArgs 개체를 통해 전달된 마지막 패킷의 X 및 Y 값을 가져옵니다. 패킷 데이터의 처음 두 위치는 항상 X 및 Y 값이 차지합니다.

Private Sub mInkObject_NewInAirPackets2(ByVal sender As Object, ByVal e As InkCollectorNewInAirPacketsEventArgs)
    Dim DescriptorsPerPacket As Integer = 0
    ' determine how many descriptors there are per packet
    ' you could also obtain this value using:
    '   e.PacketData.Length / e.PacketCount
    ' but if you need to know which particular properties
    ' are supported (beyond X and Y which are always placed first)
    ' you will need to query e.Cursor.Tablet.IsPacketPropertySupported()
    For Each G As Guid In mInkObject.DesiredPacketDescription
        If (e.Cursor.Tablet.IsPacketPropertySupported(G)) Then
            DescriptorsPerPacket += 1
        End If
    Next

    Dim LastX As Integer = e.PacketData(DescriptorsPerPacket * (e.PacketCount - 1))
    Dim LastY As Integer = e.PacketData((DescriptorsPerPacket * (e.PacketCount - 1)) + 1)
End Sub

private void mInkObject_NewInAirPackets2(object sender, InkCollectorNewInAirPacketsEventArgs e)
{
    int DescriptorsPerPacket = 0;
    // determine how many descriptors there are per packet
    // you could also obtain this value using:
    //   e.PacketData.Length / e.PacketCount
    // but if you need to know which particular properties
    // are supported (beyond X and Y which are always placed first)
    // you will need to query e.Cursor.Tablet.IsPacketPropertySupported()

    foreach (Guid G in mInkObject.DesiredPacketDescription)
    {
        if (e.Cursor.Tablet.IsPacketPropertySupported(G))
        {
            DescriptorsPerPacket++;
        }
    }

    int LastX = e.PacketData[DescriptorsPerPacket * (e.PacketCount - 1)];
    int LastY = e.PacketData[(DescriptorsPerPacket * (e.PacketCount - 1)) + 1];
