for (int pageCount = 1; pageCount <= 3; pageCount++) {
// Create stream object to save the output image
try (ByteArrayOutputStream imageStream = new ByteArrayOutputStream()) {
// Create JpegDevice object where second argument indicates the quality of
// resultant image
JpegDevice jpegDevice = new JpegDevice(200);
// Convert a particular page and save the image to stream
jpegDevice.process(pdfDocument.getPages().get_Item(pageCount), imageStream);
