            fr = new FileReader(file_name);
            PdfWriter.getInstance(document, System.out);

            document.add(new Paragraph("\n"));
            //Converting the Html content to htmldataelements which we will use this in next steps
            ArrayList htmlContentList = HTMLWorker.parseToList(fr, null);

            //fetch the html content line by line and adding the content to pdf document.
            for (int htmlDataCntr = 0; htmlDataCntr < htmlContentList.size(); htmlDataCntr++) {
             Element htmlDataElement = (Element) htmlContentList.get(htmlDataCntr);
                if(htmlDataElement!=null){
