        shape = presentation.getSlides().get(0).getShapes().appendShape(ShapeType.RECTANGLE, new Rectangle2D.Double(290, 300, 150, 100));
        shape.getFill().setFillType(FillFormatType.GRADIENT);
        shape.getFill().getGradient().getGradientStops().append(0, KnownColors.LIGHT_SKY_BLUE);
        shape.getFill().getGradient().getGradientStops().append(1, KnownColors.ROYAL_BLUE);
        shape.getShapeStyle().getLineColor().setColor(Color.white);

        //添加一个向上的箭头，并设置渐变填充
        shape = presentation.getSlides().get(0).getShapes().appendShape(ShapeType.BENT_UP_ARROW, new Rectangle2D.Double(515, 300, 130, 100));

        shape.getShapeStyle().getLineColor().setColor(Color.white);

        //保存文档
        presentation.saveToFile("AddShapes.pptx", FileFormat.PPTX_2010);
