IStylusSyncPlugin.Packets Method
Assembly: Microsoft.Ink (in microsoft.ink.dll)
'Declaration Sub Packets ( _ sender As RealTimeStylus, _ data As PacketsData _ ) 'Usage Dim instance As IStylusSyncPlugin Dim sender As RealTimeStylus Dim data As PacketsData instance.Packets(sender, data)
void Packets ( RealTimeStylus sender, PacketsData data )
function Packets (
sender : RealTimeStylus,
data : PacketsData
)
Not applicable.
Parameters
- sender
The RealTimeStylus object that called this method.
- data
Information about the stylus movement.
You can modify the packet data by calling the inherited SetData method of the PacketsData object contained in the data parameter.
Note: |
|---|
| An ArgumentExceptionArgumentException exception is thrown by the SetData method if the length of the array in the value parameter is not a multiple of the value of the inherited PacketPropertyCount property. |
You can cancel the packets by calling the SetData method with the value parameter set to null (Nothing in Microsoft Visual Basic .NET).
This C# example is excerpted from the RealTimeStylus Plug-in Sample. The example implements a Packets method that draws a small circle in the location of each new packet received.
public void Packets(RealTimeStylus sender, PacketsData data) { // For each new packet received, extract the x,y data // and draw a small circle around the result. for (int i = 0; i < data.Count ; i += data.PacketPropertyCount) { // Packet data always has x followed by y followed by the rest Point point = new Point(data[i], data[i+1]); // Since the packet data is in Ink Space coordinates, we need to convert to Pixels... point.X = (int)Math.Round((float)point.X * (float)myGraphics.DpiX/2540.0F); point.Y = (int)Math.Round((float)point.Y * (float)myGraphics.DpiY/2540.0F); // Draw a circle corresponding to the packet myGraphics.DrawEllipse(Pens.Green, point.X - 2, point.Y - 2, 4, 4); } }
