        PDFRenderer renderer = new PDFRenderer(doc);
        int pageCount = doc.getNumberOfPages();
        for (int i = 0; i < pageCount; i++) {
            BufferedImage image = renderer.renderImageWithDPI(i, 144); // Windows native DPI
            // BufferedImage srcImage = resize(image, 240, 240);//产生缩略图
            ImageIO.write(image, "png", new File("C:\Users" + "\" + "wb" + "_" + (i + 1) + "." + "png"));
        }
    } catch (IOException e) {
        e.printStackTrace();
