  NameDescription
Public methodCheckAccessDetermines whether the calling thread has access to this object. (Inherited from DependencyObject.)
Public methodClearValueClears the local value of a dependency property. (Inherited from DependencyObject.)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
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.)

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.

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>
