The following works for me for Chrome and Firefox:

html2canvas(document.body, {
      proxy: "server.js",
      useCORS: true,
      onrendered: function(canvas) {
        document.body.appendChild(canvas);
      }
    });

where server.js is https://github.com/niklasvh/html2canvas-proxy-nodejs There are other proxies available for PHP and Python that I haven't tried yet. I cannot post both but if you google "html2canvas proxy" you'll be able to find the others if you need them.

  • I use html2canvas (from html2canvas.hertzen.com) to capture screenshot. I got this strange error like this: The code of my webpage is put on one host, say Host A. If my webpage contains an image on another host, say Host B, then I hit this error: Cross-origin image load denied by Cross-Origin Resource Sharing policy However, the confusing part is that if Host B is facebook (my image is a direct link to facebook https://fbcdn-profile-a.akamaihd.net/hprofile-ak-ash4/372701_100000684388457_1551561655_q.jpg) then the error disappear. – HoangHieu Aug 04 '13 at 09:12
