 ps.addAnnotation(PdfAnnotation.createText(copy, new Rectangle(50, 180, 70, 200), "Hello", "No Thanks", true, "Comment"));
 PdfContentByte under = ps.getUnderContent();
 under.addImage(img);
 PdfContentByte over = ps.getOverContent();
 over.beginText();
 over.setFontAndSize(bf, 18);
 over.setTextMatrix(30, 30);
 over.showText("total page " + totalPage);
 over.endText();
