How can I control the resolution of outpainting?

[IamTirion]

Or is it possible to do that?

Configuration of the outpainting size is not (yet) possible and currently fixed to 30% of the original image dimension in which you want to expand in. See code here: https://github.com/lllyasviel/Fooocus/blob/main/modules/async_worker.py#L528-L545
