重现代码参考:

Code: Select all

Presentation ppt = new Presentation();
            ppt.loadFromStream(in, FileFormat.AUTO);

            // all slides
            for (int i = 0; i < ppt.getSlides().size(); i++) {
                ISlide slide = ppt.getSlides().get(i);
                // 转为缩略图，按照目标宽高等比例转化
                BufferedImage img = slide.saveAsImage();
                ByteArrayOutputStream os = new ByteArrayOutputStream();
                ImageIO.write(img, THUMBNAIL_FORMAT, os);
                byte [] byttes = i, os.toByteArray();
