Re: [webkit-dev] Canvas API in Webkit
Hi Dont really know for which platform/port of webkit u want to do this. If its a gtk port u can use a cairo for doing the same . If its s60 (if at all u r experimenting) then using CFbsBitmapDevice context u can create a memory bitmap and then draw it onto graphics context. Webkit also does same kind of operation when it renders its contents on webview. So webkit already does it ... u just need to find way to manipulate. Please correct me if i am wrong on this :) Thanks & Regards Niilesh On Sat, Dec 27, 2008 at 9:49 AM, Lucius Fox wrote: > > > On Thu, Dec 25, 2008 at 12:09 PM, Darin Adler wrote: >> >> On Dec 24, 2008, at 7:48 PM, Lucius Fox wrote: >> >>> Thanks.

Not the desktop version of Safari, but yes, the mobile Safari has something like this. I think the Nokia browser does too. Can you please tell me how if that is true and how is that implement? Well, those browsers aren't open source, so there's no real way for you to find out how they implemented the feature. I think it's safe to assume that they draw the web pages into a bitmap and then shrink the image. It certainly has nothing to do with the HTML element in either case. -- Darin ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
Re: [webkit-dev] Canvas API in Webkit
Thanks. I think Safari has a 'history' feature or Nokia S60 browser which shows each url in history as a preview image'. Can you please tell me how if that is true and how is that implement?

That sounds like a good idea for an extension for canvas.
