部分ppt使用Presentation Java的截图功能会卡死

[liheyuan]

一部分ppt会卡死，只能截前面几页，后面就卡死不动了，版本8.1.2，商业授权 (之前邮件发过授权号了)
我的是openjdk 1.8，Linux

如下重现代码

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();
            }
