Rendering HTML elements to <canvas>

Is there a way to have an arbitrary HTML element rendered in a canvas (and then access its buffer...).

Solution

  • You won't get real HTML rendering to <canvas> per se currently, because canvas context does not have functions to render HTML elements.

    There are some emulations:

    html2canvas project http://html2canvas.hertzen.com/index.html (basically a HTML renderer attempt built on Javascript + canvas)

    HTML to SVG to <canvas> might be possible depending on your use case:

    Also if you are using Firefox you can hack some extended permissions and then render a DOM window to <canvas>
