|

The whole screenshot is created with JavaScript. The only server interaction that is happening on this page is the proxy for loading the external pages/images into JSONP/CORS enabled page and onwards onto the JavaScript renderer script.
|
||||
There are a lot of problems of loading external pages, even with a proxy, and as such many pages will not render at all. If you wish to try the script properly, I recommend you get a copy of the source from <a href="https://github.com/niklasvh/html2canvas">here</a> instead.
