How to: Draw Text to a Visual
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;
}
