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.
The script renders the current page as a canvas image, by reading the DOM and the different styles applied to the elements.
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 to get the content to the same origin.
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.
The library should work fine on the following browsers (with Promise
polyfill):
As each CSS property needs to be manually built to be supported, there are a number of properties that are not yet supported.
The html2canvas library utilizes Promise
s and expects them to be available in the global context. If you wish to
support older browsers that do not natively support Promise
s, please include a polyfill such as
es6-promise before including html2canvas
.
To render an element
with html2canvas, simply call:
html2canvas(element[, options]);
The function returns a Promise containing the <canvas>
element. Simply add a promise fulfillment handler to the promise using then
:
html2canvas(document.body).then(function(canvas) {
document.body.appendChild(canvas);
});

If you wish to contribute to the project, please send the pull requests to the develop branch. Before submitting any changes, try and test that the changes work with all the support browsers. If some CSS property isn't supported or is incomplete, please create appropriate tests for it as well before submitting any code changes.
