Examples
The following example demonstrates how to change the stylus points in the OnStylusDown method. To create a StylusPlugIn that restricts ink to a certain area, see the StylusPlugIn overview.
protected override void OnStylusDown(RawStylusInput rawStylusInput)
{
// Run the base class before modifying the data
base.OnStylusDown(rawStylusInput);
// Get the StylusPoints that have come in
StylusPointCollection stylusPoints = rawStylusInput.GetStylusPoints();
// Modify the (X,Y) data to move the points
// inside the acceptable input area, if necessary
for (int i = 0; i < stylusPoints.Count; i++)
{
StylusPoint sp = stylusPoints[i];
if (sp.X < 50) sp.X = 50;
if (sp.X > 250) sp.X = 250;
if (sp.Y < 50) sp.Y = 50;
if (sp.Y > 250) sp.Y = 250;
stylusPoints[i] = sp;
}
// Copy the modified StylusPoints back to the RawStylusInput
rawStylusInput.SetStylusPoints(stylusPoints);
}
Protected Overrides Sub OnStylusDown(ByVal rawStylusInput As RawStylusInput)
' Run the base class before we modify the data
MyBase.OnStylusDown(rawStylusInput)
' Get the StylusPoints that have come in
Dim stylusPoints As StylusPointCollection = rawStylusInput.GetStylusPoints()
' Modify the (X,Y) data to move the points
' inside the acceptable input area, if necessary.
Dim i As Integer
For i = 0 To stylusPoints.Count - 1
Dim sp As StylusPoint = stylusPoints(i)
If sp.X < 50 Then
sp.X = 50
End If
If sp.X > 250 Then
sp.X = 250
End If
If sp.Y < 50 Then
sp.Y = 50
End If
If sp.Y > 250 Then
sp.Y = 250
End If
stylusPoints(i) = sp
Next i
' Copy the modified StylusPoints back to the RawStylusInput
rawStylusInput.SetStylusPoints(stylusPoints)
End Sub
