However, the key place where the readback is done for DRT is in WebViewImpl::paint, Source/WebKit/chromium/src/WebViewImpl.cpp. When running in DRT, the passed-in WebCanvas is non-NULL, and the readback is done.

Thanks for the detailed reply.

It seems that Qt's WebKit and DRT also have to be modified in the same way for a pixel-test.

I will try to patch this in the near future.
