NPAPI或javascript的屏幕截图

Question

I'm writing an npapi plugin. I was wondering if there is a way to capture the browser screen from my plugin using either npapi or javascript.

Any help would be appreciated.

Thanks

没有办法用JavaScript做到这一点，但是您可以用本机代码做到这一点，不是吗？

Answer 2

Someone on the FireBreath mailing list recently created a plugin with FireBreath that does this on windows; he was using it with selenium for automation testing, I believe. He had mentioned possibly making it open source; I'd consider posting a question to the FireBreath list and see if he's willing to share.

In Mozilla you can achieve this by using Canvas.prototype.drawWindow() . But access to this method is allowed only to privileged code, ie extensions.
