At this moment I've got AI Remove Background working, using IOPaint that runs locally on my laptop. It still needs some fine tuning, but it works.

Now I am working on 'inpaint' (filling a selection with a generated background). I am struggling now how to make a mask from a selection. The GIMP API has many procedures, but just copying a selection seems not to be easy. Is there anyone who has some experience with this?


P.S. I am new to Gimp Forum, so maybe I missed earlier questions/discussions like this.

Layer > Mask > Add layer mask, chose "Selection"

Sorry, I must have been unclear. I want to create a mask from a selection using python code. I would very much like to know which gimp procedures to use for achieving this. I am thinking of edit_copy and edit_paste_new_image, but the first has a drawable is argument and the second an image. So maybe it's not straightforward.
