[Skunkworks] Convert Html + SVG to Canvas/png on the Client Side

Hello people, Has anyone tried converting Html + SVG to Canvas or PNG on the clients. I want to save a section of a page that have both a map/chart plus the html contents in that region. I have tried this plugins without any success 1. https://github.com/niklasvh/html2canvas => this works quite well to save a html but it omits the SVGs. 2. https://code.google.com/p/canvg/ => saves svgs effectively but not html.
