What I want is to create a vector drawing program with layers, but to avoid using transparency / opacity, I want to draw each shape from lowest layer to highest layer onto a single bitmap. For the filling, I want to floodfill the shape. My issue is that, if I have a shape that is drawn then floodfilled, then the next shape overlaps it a bit and that new shape's border is the same as the other one's then floodfill will only partially fill it. Is there a way given a shape's coordinates that I can find the actual bounds for floodfill rather than use a target color? Thanks
