        // TODO Auto-generated method stub
        ReaderTextService rts = new ReaderTextService();
        for(List<WordWithTextPositions> l : rts.readWordWithTextPositions("/Users/hhhtide/Desktop/PDF_Extract/Data/table1.pdf")) {
              for(WordWithTextPositions wwtp : l) {
                  for(TextPosition tp : wwtp.getTextPositions()) {
                    System.out.println("word:" + tp.getUnicode().toString() + " X:" + tp.getX());
                  }
              }
