Methods

Name Description
CheckAccess Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)
ClearValue Clears the local value of a dependency property. (Inherited from DependencyObject.)
Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
GetAnimationBaseValue Returns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
GetBounds Retrieves the bounding box for the Stroke object.
GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
GetType Gets the Type of the current instance. (Inherited from Object.)
GetValue Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
HitTest Indicates whether a specified StylusPointCollection intersects with a Stroke object.
MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
ReadLocalValue Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
SetValue Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
ToString Returns a string that represents the current object. (Inherited from Object.)

Remarks

A Stroke is the data object that is collected from a pointing device, such as a tablet pen or your finger. The Stroke can be created and manipulated programmatically, and can be represented visually on an ink-enabled element, such as the InkPresenter. A Stroke contains information about both its position and appearance. The StylusPoints property is a collection of StylusPoint objects that specifies the geometry of the Stroke. The DrawingAttributes property specifies a stroke's appearance.

Examples

The following code example shows how can create a static stroke using XAML.

<Canvas>
    <InkPresenter x:Name="MyIP" Height="100" Width="200" Background="Transparent">
        <InkPresenter.Strokes>
            <StrokeCollection>
                <Stroke>
                    <Stroke.DrawingAttributes>
                        <DrawingAttributes Color="Red" OutlineColor="Black" Width="5" Height="5"/>
                    </Stroke.DrawingAttributes>
                    <Stroke.StylusPoints>
                        <StylusPoint X="50" Y="50"/>
                        <StylusPoint X="55" Y="55"/>
                        <StylusPoint X="60" Y="60"/>
                        <StylusPoint X="65" Y="65"/>
                        <StylusPoint X="70" Y="70"/>
                        <StylusPoint X="75" Y="75"/>
                    </Stroke.StylusPoints>
                </Stroke>
            </StrokeCollection>
        </InkPresenter.Strokes>
    </InkPresenter>
</Canvas>
