An alternative to RGBA format for CefRenderHandler::OnPaint

[aligre]

Hello

In the callback CefRenderHandler::OnPaint, the input buffer is in BGRA format and, when the transparency is enabled, the BGR values are alpha premultiplied.
Also the origin of this buffer is upper-left.
In our application, textures are expected (by the visualization layer of code) to have an bottom-left origin and not to be alpha-premultiplied.
This constraint forces us to flip the buffer and, fortunatly rarely, to unmultiply by alpha coefficient.

Is there a way to specify to CEF to return a bottom-left not premultiplied buffer ?

Not sure but I think this kind of question has been already posted and the answer was no.
In that case, does an evolution of CEF possible in that way?

Thanks

ps : Of course, if this is not possible at all, we'll try to modify our visualization layer of code to accept CEF buffer format

It’s not currently supported by CEF. Adding this option would require support in Chromium as a prerequisite.
