StylusPoint.PressureFactor Property
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Gets or sets the pressure factor of the stylus on the screen.
Namespace: System.Windows.Input
Assembly: System.Windows (in System.Windows.dll)
Syntax
'Declaration
Public Property PressureFactor As Single
public float PressureFactor { get; set; }
Property Value
Type: System.Single
The pressure factor of the stylus on the screen. The default is 0.5.
Exceptions
| Exception | Condition |
|---|---|
| ArgumentOutOfRangeException | PressureFactoris set to a value that is less than 0 or greater than 1.0. |
Remarks
The permitted range is 0 to 1.0. Values obtained from input will always be within this range. Setting the value to outside this range causes an exception to be thrown.
The value is a factor of the total possible pressure.
The typical scenario for this property is to modify the DrawingAttributes based on the PressureFactor captured in a StylusPoint obtained from user input. Notice that while PressureFactor comes from individual points, DrawingAttributes must apply to an entire Stroke.
XAML Attribute Usage
<StylusPoint PressureFactor="double"/>
Examples
The following code example demonstrates how to get the member Y property. This is part of a larger example available in StylusPoint class overview.
'StylusPoint objects are collected from the MouseEventArgs and added to MyStroke
Private Sub MyIP_MouseMove(ByVal sender As Object, ByVal e As MouseEventArgs)
If (Not (MyStroke) Is Nothing) Then
MyStroke.StylusPoints.Add(e.StylusDevice.GetStylusPoints(MyIP))
XTB.Text = ("" + e.StylusDevice.GetStylusPoints(MyIP)(0).X)
YTB.Text = ("" + e.StylusDevice.GetStylusPoints(MyIP)(0).Y)
PressureTB.Text = ("" + e.StylusDevice.GetStylusPoints(MyIP)(0).PressureFactor)
End If
End Sub
//StylusPoint objects are collected from the MouseEventArgs and added to MyStroke
private void MyIP_MouseMove(object sender, MouseEventArgs e)
{
if (MyStroke != null)
{
MyStroke.StylusPoints.Add(e.StylusDevice.GetStylusPoints(MyIP));
XTB.Text = "" + e.StylusDevice.GetStylusPoints(MyIP)[0].X;
YTB.Text = "" + e.StylusDevice.GetStylusPoints(MyIP)[0].Y;
PressureTB.Text = "" + e.StylusDevice.GetStylusPoints(MyIP)[0].PressureFactor;
}
}
