demo：
final PDDocument load = PDDocument.load(file,
MemoryUsageSetting.setupTempFileOnly(-1)
.setTempDir(new File("D:\\fcs\\test")));
int numberOfPages = load.getNumberOfPages();
for (int i = 0; i < numberOfPages; i++) {
final int finalI = i;
PDFRenderer renderer = new PDFRenderer(load);
renderer.setSubsamplingAllowed(true);
int pageIndex = finalI;
float scale = 2.0f;
try {
BufferedImage bufferedImage =
renderer.renderImage(pageIndex, scale, ImageType.RGB);
File file1 = new
File("D:\\fcs\\test/test/imagepdfbox" + pageIndex + ".jpg");
ImageIO.write(bufferedImage, "jpg",file1);
} catch (Exception e) {
System.out.println(e);
