Remarks

A Stroke is the data object that is collected from a pointing device, such as a tablet pen or a mouse. 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>
