        new Point2D.Float(1f, 0f)
), 0.4f));

Create style

Style style = new Style()
        .setBlur(20f)
        .setBorder(new StyleBorder(20)
                .setBorderWidth(1.5f)

                        new Point2D.Float(0, 0),
                        new Point2D.Float(1, 1)
                ))
                .setDropShadow(new StyleDropShadow(
                        new Color(0, 0, 0),

                        new Point2D.Float(0, 0),
                        new Point2D.Float(1, 1)
                ), 0.1f)
        );
