WK2 Qt port uses WebCoordinatedSurface to share a bitmap between processes.
(It is a surface for Coordinated Graphics).

And it's backed by ShareableBitmapQt.

You can take a look at:
Source/WebKit2/Shared/CoordinatedGraphics/WebCoordinatedSurface
Source/WebKit2/Shared/qt/ShareableBitmapQt

Hi All,
      I have been going through the webkit 2 code. But I am not able to findout how the bitmaps are shared between the webprocess and the UI process. Can anybody point me to the appropriate class or share some details on it?

It depends on the port. Which port are you looking at?

(Mac WebKit2 uses remotely-hosted CoreAnimation layers, FWIW, so it’s kind of “magic” from WebKit2’s perspective).

You should look at and around the DrawingArea implementations.

Thanks and Regards,
Vishvesh
