Wie füge ich Textknoten in JavaFX einen Unschärfeeffekt hinzu?

public class TextBlurEffect extends Application {
   public void start(Stage stage) throws FileNotFoundException {
      //Creating a text object
      String str = "Welcome to Tutorialspoint";
      Text text = new Text(30.0, 80.0, str);
      //Setting the font
      Font font = Font.font("Brush Script MT", FontWeight.BOLD,
      FontPosture.REGULAR, 65);
      text.setFont(font);
      //Setting the color of the text
      text.setFill(Color.BROWN);
      //Setting the width and color of the stroke
      text.setStrokeWidth(2);
      text.setStroke(Color.BLUE);
      //Setting the blur effect to the text
      GaussianBlur blur = new GaussianBlur();
      text.setEffect(blur);
      //Setting the stage
      Group root = new Group(text);
      Scene scene = new Scene(root, 595, 150, Color.BEIGE);
      stage.setTitle("Blur Effect");
      stage.setScene(scene);
      stage.show();
   }
   public static void main(String args[]){
      launch(args);
   }
}
