What would your feature do ?

Hello guys! There's a small issue when I want to swap a face to PNG images (with RGBA) By default SD WebUI cuts Alpha-channel when you postprocess the image via Extras Tab

E.g.: I load the image with transparency and want to swap the face So I get the following result:

As we can see the alpha channel is lost

With this little fix we can operate with all 4 channels of the input image - and the result is:

If there's no any other specific reason to convert the input to the RGB for Extras (except RGB mode needs for restorers) - I can add the PR

Proposed workflow

1. Go to the Extras Tab
2. Load PNG (of some person) with transparency
3. Try to swap the face via ReActor
4. Get the result with transparency as well

Ideally a PR should be made upstream. It should also be verified it doesn't break any functionality with non-RGBA images. https://github.com/AUTOMATIC1111/stable-diffusion-webui/pulls

There is this very significant comment there from the author...

Gourieff commented 2 days ago ... 3. Insightface doesn't work with Alpha-channel as well :( It needs BGR as the input...

I don't think this is an issue for sd-webui-forge (yet).

EDIT

I shall eat my hat, as this issue is from the author of ReActor (LOL!)

stoked that it seems like ReActor may be able to process layerdiffuse output!
