Answer 1

This is the html2canvas bug report.

I was able to fix the Uncaught Error: IndexSizeError: DOM Exception 1 by patching the html2canvas.js file.

by this:

var imgData = canvas.getContext("2d").getImageData(bounds.left, bounds.top, bounds.width, bounds.height);
ctx.putImageData(imgData, 0, 0);
