I have a background layer (gray in the example) and on top of that a foreground layer with black line art. I converted the line art to a path (using Path -> Trace Bitmap).
How do I prevent the background from shining through, like in the example? Clearly you should not see the fence through the person.
I made an new layer, manually traced the outline of the foreground (person), and put that shape in the "shine through protection" layer. That kind of works, until I change / move / resize the foreground picture. So I am wondering if there is an easier / better way of doing this.
I cannot just select a white fill because the traced path is on the drawn lines, not the area included by these lines. The picture below shows a red fill and black stroke for the foot:
So maybe I am doing the tracing wrong.
