[WinError 32] The process cannot access the file because it is being used by another process

[ArimanBlack]

The error appears on windows machines with python 3.10 installed because the code tries to a delete file while pillow still holds it's open.

src/twain.py:2048

Image.open(bmppath).save(filepath)
os.remove(bmppath)

change to:

                with Image.open(bmppath) as im:
                    im.save(filepath)
                    im.close()
                    os.remove(bmppath)

I tried to create a pull request for it but I don't have enough rights
