function runPromise(x) {
var canvasnx = ''; var promisex = []; var height = 0; var promise = new Promise(function (resolve, reject) { var div = document.getElementById("ch_dndBoard1"); html2canvas(div, { useCORS: true, allowTaint: true, onrendered: function (canvasn) { var position = 0; var valuesx = []; canvasnx = canvasn; var extra_canvas = document.createElement("canvas"); var element = document.getElementById("paint_1"); var pagecount = element.getElementsByTagName('canvas').length; height = canvasn.height / pagecount; extra_canvas.setAttribute('width', canvasn.width); extra_canvas.setAttribute('height', height); var ctx = extra_canvas.getContext('2d'); console.log("canvasncanvasncanvasncanvasn", canvasn.toDataURL("image/jpeg", 1.0) ); for (var i = 0; i < pagecount; i++) { ctx.drawImage(canvasn, 0, position, canvasn.width, height, 0, 0, canvasn.width, height); // console.log("canvasxxxxxxxxxxx" , position , canvasn.width ,height ); position += (height); //position += (height + 5.125); var myImage = extra_canvas.toDataURL("image/jpeg", 1.0); valuesx.push(myImage); } resolve([valuesx, height]); } }); }); promise.then(function (values) { var orient = x.orientation; console.log(values); var pdf = new jsPDF(orient, 'pt', [canvasnx.width, values[1]]); console.log(values, "values.lengthvalues.length"); for (var i = 0; i < values[0].length; i++) { console.log("condition ", values[0][i]); pdf.addImage(values[0][i], 'JPEG', 0, 0, canvasnx.width, values[1]); pdf.addPage(); } var pageCount = pdf.internal.getNumberOfPages(); pdf.deletePage(pageCount); var pdf_data = btoa(pdf.output()); $.ajax({ type: "post", url: x.siteUrl, data: { pdf_data: pdf_data, login_user_id: x.loginId, project_id:x.projectId, newPdf: x.newPdf, original_pdf_name: x.originalName, client_name: x.clientName, user_name: x.userName, use_icons_json: x.icons_jsonData, use_comments_json: x.comments_jsonData,
