How to: Draw Text to a Visual

.NET Framework 3.0

The following example shows how to draw text to a DrawingVisual using a DrawingContext object. A drawing context is returned by calling the RenderOpen method of a DrawingVisual object. You can draw graphics and text into a drawing context.

To draw text info the drawing context, use the DrawText method of a DrawingContext object. When you are finished drawing content into the drawing context, call the Close method to close the drawing context and persist the content.

Example

// Create a DrawingVisual that contains text.
private DrawingVisual CreateDrawingVisualText()
{
    // Create an instance of a DrawingVisual.
    DrawingVisual drawingVisual = new DrawingVisual();

    // Retrieve the DrawingContext from the DrawingVisual.
    DrawingContext drawingContext = drawingVisual.RenderOpen();

    // Draw a formatted text string into the DrawingContext.
    drawingContext.DrawText(
       new FormattedText("Click Me!",
          CultureInfo.GetCultureInfo("en-us"),
          FlowDirection.LeftToRight,
          new Typeface("Verdana"),
          36, Brushes.Black),
          new Point(200, 116));

    // Close the DrawingContext to persist changes to the DrawingVisual.
    drawingContext.Close();

    return drawingVisual;
}
