The script allows you to take "screenshots" of webpages or parts of it, directly on the users browser. The screenshot is based on the DOM and as such may not be 100% accurate to the real representation as it does not make an actual screenshot, but builds the screenshot based on the information available on the page.
It does **not require any rendering from the server**, as the whole image is created on the **client's browser**. However, as it is heavily dependent on the browser, this library is *not suitable* to be used in nodejs.
It doesn't magically circumvent any browser content policy restrictions either, so rendering cross-origin content will require a [proxy](https://github.com/niklasvh/html2canvas/wiki/Proxies) to get the content to the [same origin](http://en.wikipedia.org/wiki/Same_origin_policy).
The script is still in a **very experimental state**, so I don't recommend using it in a production environment nor start building applications with it yet, as there will be still major changes made.
