and print screen/screenshot

问题:

Is there any way to print screen and get the clipboard data into an html5 canvas element?

In other words, is there a way to read print screened clipboard data (pixels, probably) with javascript?

Or once again this is the case where javascript cannot get such data?

If any of the questions has the answer value of yes, I'd like to know a bit more details.

Thanks in advance!

You want to capture the screen and display it in canvas. Please see following link

No, there is not, for security reasons.

The only thing that comes close is Mozilla's drawWindow command which only works locally.

Looks like there is a way, it's Chrome only, but it works flawlessly.

I hope it's only a matter of time until other browsers implement similar features, but yeah, there is a way. Plus, this could be tweaked to do almost anything.
