Is i开发者_开发问答t possible to save rendered canvas back to a file in Google Chrome?

I have tried this:

canvas.getAsFile('foo.jpg','image/jpeg')

Doesn't work.

This works only in Firefox:

canvas.mozGetAsFile('foo.jpg')

Of course I can and probably will just send raw base64 encoded string to server and decode it there.

But if it's possible to do it on client-side, i would prefer doing it there.
