List<PDPage> pages = pdDoc.getDocumentCatalog().getAllPages();

if(pages.size()>0){

PDJpeg img = new PDJpeg(pdDoc, in);
PDPageContentStream stream = new PDPageContentStream( pdDoc, pages.get(0));
stream.drawImage(img, 60, 60);
stream.close();
}

PDPageContentStream stream = new PDPageContentStream( pdDoc, pages.get(0));

PDPageContentStream stream = new PDPageContentStream( pdDoc, pages.get(0), true, true);
