StylusPoint Structure

StylusPoint Structure

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Represents a single point collected while the user is entering ink strokes with the stylus or mouse.

Namespace:  System.Windows.Input
Assembly:  System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.

public struct StylusPoint
<StylusPoint .../>

The StylusPoint type exposes the following members.

Public methodStylusPointInitializes a new instance of the StylusPoint class.

Public propertyPressureFactorGets or sets the pressure factor of the stylus on the screen.
Public propertyXGets or sets the value for the x-coordinate of the StylusPoint.
Public propertyYGets or sets the value for the y-coordinate of the StylusPoint.

Public methodEqualsIndicates whether this instance and a specified object are equal. (Inherited from ValueType.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from ValueType.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns the fully qualified type name of this instance. (Inherited from ValueType.)

The StylusPoint structure represents a single point. All StylusPoint objects contain properties that indicate the (x, y) coordinates and the pressure.


You can get the relevant PressureFactor only if the device supports it. Otherwise, PressureFactor will have a default value of 0.5.

Multiple StylusPoint objects typically make up a Stroke object. The Stroke object stores the stylus points in the StylusPoints property.

The following code example displays the x-coordinate, y-coordinate, and pressure data of each stylus point as they are added to a stroke.

public Page()

Stroke MyStroke;

//A new stroke object, MyStroke, is created and is added to the StrokeCollection object
//of the InkPresenter, MyIP
private void MyIP_MouseLeftButtonDown(object sender, MouseEventArgs e)
    StylusPointCollection MyStylusPointCollection = new StylusPointCollection();
    MyStroke = new Stroke(MyStylusPointCollection);


//StylusPoint objects are collected from the MouseEventArgs and added to MyStroke
private void MyIP_MouseMove(object sender, MouseEventArgs e)
    if (MyStroke != null)
        XTB.Text = "" + e.StylusDevice.GetStylusPoints(MyIP)[0].X;
        YTB.Text = "" + e.StylusDevice.GetStylusPoints(MyIP)[0].Y;
        PressureTB.Text = "" + e.StylusDevice.GetStylusPoints(MyIP)[0].PressureFactor;

//MyStroke is completed
private void MyIP_LostMouseCapture(object sender, MouseEventArgs e)
    MyStroke = null;

private void SetBoundary()
    RectangleGeometry MyRectangleGeometry = new RectangleGeometry();
    MyRectangleGeometry.Rect = new Rect(0, 0, MyIP.ActualHeight, MyIP.ActualWidth);
    MyIP.Clip = MyRectangleGeometry;
