                x += (100 + presentation.getSlideSize().getSize().getWidth()/5);

            }
                x = 30;
                y += (100 + presentation.getSlideSize().getSize().getHeight()/6);

        }

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