That API is more about desktop zooming. I wouldn't really recommend
using it as a model for zooming on a mobile platform.

Hello everyone,
I was trying to zoom a web page (text + images) through WebKit API:
frame->setZoomFactor(). The call forces WebKit to recalculate the
page layout and send repaints to the application via Chrome Client.
What I have noticed is that zooming takes considerable time and that
effect becomes more evident running on an embedded platform. The
number of repaint calls that are routed to the application through
Chrome Client are far more than for the case when the page is
displayed without zooming.
As a result, from the user point of view, the zooming operation
takes considerable time that is proportional to the content length
of the page being displayed. For instance if BBC mobile is
displayed, the page is zoomed quickly from zoom factor of 1.0 to
1.2. However, for edition.cnn.com, it takes quite a few seconds to
complete and there are far more repaint calls sent to the
application. Is this the normal behavior? Is there a way to get this
done in a much quicker way, even for sites with more content? Any
suggestion in this regard will be greatly appreciated. Thanks.
Regards,
Javed
