Ejemplos

En el ejemplo siguiente se muestra cómo usar dos DrawingAttributes objetos para simular mediante un lápiz y un resaltador en el mismo InkCanvas. La propiedad del StylusTip resaltador se establece en Rectángulo.

En el ejemplo se supone que el elemento raíz del archivo "XAML" es un DockPanel denominado root. También supone que hay un Button llamado btnToggleHighlighter y que el Click evento se ha conectado al controlador de eventos.

InkCanvas inkCanvas1 = new InkCanvas();
DrawingAttributes inkDA;
DrawingAttributes highlighterDA;
bool useHighlighter = false;

// Add an InkCanvas to the window, and allow the user to 
// switch between using a green pen and a purple highlighter 
// on the InkCanvas.
private void WindowLoaded(object sender, EventArgs e)
{
    inkCanvas1.Background = Brushes.DarkSlateBlue;
    inkCanvas1.DefaultDrawingAttributes.Color = Colors.SpringGreen;

    root.Children.Add(inkCanvas1);

    // Set up the DrawingAttributes for the pen.
    inkDA = new DrawingAttributes();
    inkDA.Color = Colors.SpringGreen;
    inkDA.Height = 5;
    inkDA.Width = 5;
    inkDA.FitToCurve = false;

    // Set up the DrawingAttributes for the highlighter.
    highlighterDA = new DrawingAttributes();
    highlighterDA.Color = Colors.Orchid;
    highlighterDA.IsHighlighter = true;
    highlighterDA.IgnorePressure = true;
    highlighterDA.StylusTip = StylusTip.Rectangle;
    highlighterDA.Height = 30;
    highlighterDA.Width = 10;

    inkCanvas1.DefaultDrawingAttributes = inkDA;
}

// Create a button called switchHighlighter and use 
// SwitchHighlighter_Click to handle the Click event.  
// The useHighlighter variable is a boolean that indicates
// whether the InkCanvas renders ink as a highlighter.

// Switch between using the 'pen' DrawingAttributes and the 
// 'highlighter' DrawingAttributes.
void SwitchHighlighter_Click(Object sender, RoutedEventArgs e)
{
    useHighlighter = !useHighlighter;
    
    if (useHighlighter)
    {
        switchHighlighter.Content = "Use Pen";
        inkCanvas1.DefaultDrawingAttributes = highlighterDA;
    }
    else
    {
        switchHighlighter.Content = "Use Highlighter";
        inkCanvas1.DefaultDrawingAttributes = inkDA;
    }
}
