jsPDF plugin issue & solution

Dynamic Content Issue

jsPDF provides script functions to add text and images in pdf object, but aligning them in the pdf file is very critical. As we need to mention top and left positions for elements, dynamic content creates issues due to its content height.

CSS Availability

jsPDF support very less css attributes like setFontSize, setTextColor, setFontStyle etc.


To resolve both issues we would suggest using another jquery plugin html2canvas. Html2canvas plugin enables us to capture screen from the current page. The plugin provides result in base64 format that can be added to jsPDF. Sample code is provided with an example below.

Code Sample Live Example
		var pdf = new jsPDF();
			letterRendering: 1, allowTaint : true,useCORS: true,
			onrendered: function (canvas) {
				var _imgData = canvas.toDataURL("image/jpeg");
				pdf.addImage(_imgData, 'JPEG', 4, 0);"download.pdf");
