I have a Webkit DOMElement, a div for example. Now I want a renderized NSImage or NSBitmapImageRep of it.

It's like a screenshot of a DOMElement.

Public API choices:

-[NSView cacheDisplayInRect:toBitmapImageRep:]
-[NSBitmapImageRep initWithFocusedViewRect:]

Private WebKit method:

-[DOMElement renderedImage]

renderedImage didn't work, in my case. My DOMElement is a SVG group . It returns a NSImage without any representations. – Ratata Tata Dec 13 '10 at 18:48
I update my Webkit version. Now, private method works, thanks! – Ratata Tata Dec 14 '10 at 00:22
Believe `-renderedImage` was added in Safari/WebKit 4 if that helps. – Mike Abdullah Dec 14 '10 at 10:52
How do you update the webkit version and how do you know what version do you have? – Petruza Aug 21 '11 at 04:59
WebKit updates are delivered as part of Safari or OS updates. Probably he installed Safari 4.1 or 5.0 – Mike Abdullah Sep 04 '11 at 21:28
