88. Scale

We have two rectangle, red and green, at same location and with same size. However the green is scaled down 50% in both x and y directions.

The pivot point corresponds to center left of the rectangles (50, 75). This point will not change position during the scaling.

public class Ex88 extends Application {

        Application.launch(args);
    }

    @Override
    public void start(Stage stage) {
        Rectangle rect1 = new Rectangle(50, 50, 100, 50);
        rect1.setFill(Color.rgb(255, 0, 0, 0.5));

        Rectangle rect2 = new Rectangle(50, 50, 100, 50);
        rect2.setFill(Color.rgb(0, 255, 0, 0.5));
        
        Scale scale = new Scale(0.5, 0.5, 50, 75);
        rect2.getTransforms().add(scale);
        
        Group root = new Group(rect1, rect2);
        Scene scene = new Scene(root,300,200);
        
        stage.setScene(scene);
        stage.setTitle("Example 88. Scale");
        stage.show();
