        var top_left_margin = 35;
        var PDF_Width = HTML_Width + (top_left_margin * 2);
        var PDF_Height = (PDF_Width * 1.2) + (top_left_margin * 2);
        var canvas_image_width = HTML_Width;
        var canvas_image_height = HTML_Height;

        var totalPDFPages = Math.ceil(HTML_Height / PDF_Height) - 1;
     
        html2canvas(section, { allowTaint: true }).then(function (canvas) {
          var imgData = canvas.toDataURL('image/png');
          var imgWidth = 210;
          var pageHeight = 299;
          var imgHeight = canvas.height * imgWidth / canvas.width;
          var heightLeft = imgHeight;
          var top_left_margin = 15;
          var doc = new jspdf.jsPDF();
          var position = 0;
     
          doc.addImage(imgData, 'PNG',0, position, imgWidth, imgHeight+30);
          heightLeft -= pageHeight;
    
          while (heightLeft >= 0) {
              position = heightLeft - imgHeight; 
              doc.addPage();
              doc.addImage(imgData, 'PNG',0,position, imgWidth, imgHeight+30);
