    //Create screenshot of body
    html2canvas(document.body, {scale: 2,scrollY: 0,height: window.outerHeight + window.innerHeight, windowHeight: window.outerHeight + window.innerHeight, }).then(canvas => {

       document.getElementById("pdfObj").height = canvas.height / 4;
       document.getElementById("pdfObj").data = output;
