Answer 1

这是转换的方法public static List<String> pdfToImagePath(String filePath){
        List<String> list = new ArrayList<>();
        String fileDirectory = filePath.substring(0,filePath.lastIndexOf("."));//获取去除后缀的文件路径
 
        String imagePath;
        File file = new File(filePath);
        try {
            File f = new File(fileDirectory);
            if(!f.exists()){
                f.mkdir();
            }
            PDDocument doc = PDDocument.load(file);
            PDFRenderer renderer = new PDFRenderer(doc);
            int pageCount = doc.getNumberOfPages();
            for(int i=0; i<pageCount; i++){
                // 方式1,第二个参数是设置缩放比(即像素)
                // BufferedImage image = renderer.renderImageWithDPI(i, 296);
                // 方式2,第二个参数是设置缩放比(即像素)
                BufferedImage image = renderer.renderImage(i, 1.25f);  //第二个参数越大生成图片分辨率越高，转换时间也就越长
                String uuid = UUID.randomUUID().toString().replaceAll("-", "");
                imagePath = "E:/PDFToImg" + "/"+uuid+"_"+(i+1)+".jpg";
                ImageIO.write(image, "PNG", new File(imagePath));
                list.add(imagePath);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return list;
    }
