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();
}
