I am trying to generate pdf on client-side using jsPDF library. My code looks like
<script type="text/javascript" src="libs/base64.js"></script>
<script type="text/javascript" src="libs/sprintf.js"></script>
<script type="text/javascript" src="jspdf.js"></script>

doc.setFontSize(40);
doc.text(30, 20, 'Hello world!');
doc.output('datauri');
doc.addImage(imgData, 'JPEG', 15, 40, 200, 114);
</script>
but it seems to print text only and no image.
What is the problem here?
if you want to add a png image, you have to get the latest jspdf.js and add the support png libraries
<script type="text/javascript" src="libs/png_support/zlib.js"></script>
<script type="text/javascript" src="libs/png_support/png.js"></script>
<script type="text/javascript" src="jspdf.plugin.addimage.js"></script>
<script type="text/javascript" src="jspdf.plugin.png_support.js"></script>
<script type="text/javascript" src="jspdf.js"></script>
then in the script, change the format to 'PNG'
<script>
var doc = new jsPDF();
var imgData = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAMgAAABy...
doc.setFontSize(40);
doc.text(30, 20, 'Hello world!');
doc.addImage(imgData, 'PNG', 15, 40, 200, 114);
doc.output('datauri');
</script>
Include the following file to your HTML:
<script src="Scripts/jspdf/png_support/zlib.js"></script>
<script src="Scripts/jspdf/png_support/png.js"></script>
<script src="Scripts/jspdf/FileSaver.js"></script>
<script src="Scripts/jspdf/jspdf.js"></script>
<script src="Scripts/jspdf/jspdf.plugin.addimage.js"></script>
<script src="Scripts/jspdf/jspdf.plugin.png_support.js"></script>
You can get all these files from https://github.com/MrRio/jsPDF
FileSaver.js from libs/FileSaver.js zlib.js and png.js from libs/png_support.js
If you don't need to save pdf file, you can exclude FileSaver.js.
When it alerts missing some functions, opening dist/jspdf.debug.js, search for it name to find particular module containing it and include it in above list(after jspdf.js file).
call doc.output
after building the doc:
doc.addImage(imgData, 'JPEG', 15, 40, 200, 114);
doc.output('datauri');
