[webkit-dev] get the bits of the complete page

[zaheer ahmad]

hi,
iam working on the gtk port of webkit and have a need to get the
bitmap of the entire page without actually rendering it. Is there an
easy way to get in the current implementation.  one of the ways i
thought was to create a cairo surface over a memory buffer (instead of
the drawing window in webkit_page_expose_event) and pass it to the
scrollview::paint with a complete rectangle. Not sure if this is the
right track to solve this issue (also this could be performance/memory
intensive)

Any inputs would be greatly helpful.

thanks,
Zaheer

hi,
The patch does not reposition the changed document to the top of the frame
view and also does not alter the documents width/height. The same behavior
is seen with transforms from html pages(e..g scaled content goes out of the
window)
Are these known issues?

Setting the transform origin (style->setTransformOriginX(Length(0,Fixed));)
should fix the first problem.  A force layout with changed width/height for
the renderview should solve the second problem. not sure if this is the
right thing to do.
let us know your comments.

thanks,
Zaheer
