        presentation.loadFromFile("C:\\Users\\Administrator\\Desktop\\input.pptx");

        //获取第一张幻灯片
        ISlide slide= presentation.getSlides().get(0);

        Map map = new HashMap();

        //将需要被替换和用于替换的文本以键值的形式添加到Map
        map.put("#姓名#","小明");

        map.put("#地址#","成都市");
        map.put("#电话#","028-12345678");
