is there a good way to invert a black and white graphic in inkscape.
As an example, take
and invert the upper or the lower graphic.
I tried to add a layer and use exclusive-or with a black box overlay, but I it
did not do at all what I was hoping for (xor between black and white).
Is there a good way to do that without changing the color of every item?
I am an inkscape beginner, so every advice is welcome :-)
