Und warum ist translateX und translateY in meiner Szene schlecht positioniert? Ich beginne mit der Koordinate x = 100 y = 200 in reell meine reelle Koordinate y = -24,8 ... warum? Ich brauche echte Koordinaten, wann ist mein ImageView?

    primaryStage.setTitle("Title");
    Group root = new Group();
    Scene scene = new Scene(root, 800, 600, Color.WHITE);

   // border.prefHeightProperty().bind(scene.heightProperty());
    //border.prefWidthProperty().bind(scene.widthProperty());
    Image im = new Image("Images/universe.jpg", 800, 600, true, true);
    ImageView iv = new ImageView(im);

    Image iv1 = new Image("Images/Asteroid.png", 60, 50, false, false);
    ImageView iv2 = new ImageView(iv1);
    iv2.setX(100);
    iv2.setY(200);

    Path p = new Path();
    p.getElements().add(new MoveTo(100, 200));
    p.getElements().add(new LineTo(200, 400));
    PathTransition pt = new PathTransition(Duration.millis(10000), p);
    pt.setNode(iv2);
    root.getChildren().add(iv2);   
    DoubleProperty xValue = new SimpleDoubleProperty();
    xValue.bind(iv2.translateXProperty());
    xValue.addListener(new ChangeListener() {

        @Override
        public void changed(ObservableValue ov, Object t, Object t1) {
         //   System.out.println((double) t1);
        }
    });
       DoubleProperty yValue = new SimpleDoubleProperty();
    yValue.bind(iv2.translateYProperty());
    yValue.addListener(new ChangeListener() {

        @Override
        public void changed(ObservableValue ov, Object t, Object t1) {
            System.out.println((double) t1);
        }
    });
    pt.play();
    primaryStage.setScene(scene);
    primaryStage.show();
}
