I tried something which might be helpful tho not a complete solution.
Set pastemode to difference.
create a copy of image and translate 2 pixels in both x and y dimension.
copy original image over the copy and a good part of the circle will show up on a "black"
background.
You might then be able to find something to complete the missing parts (where adjacent pixels were the same).
