I was trying out various filters when I came across
-fx_slice_luminosity in GIMP.
At first glance, I assumed that each activated slice would generate a separate layer, similar to what split details or luminosity masks scripts would do. Instead, it generates two layers: a duplicate of the base layer and a layer that is the sum of all the activated slices. Is that the expected behavior?
I would find utility in the inclusion of an option to output a layer per slice; and perhaps in having more than 4 slices, but that would add more arguments to this monstrosity:
I don't know about that .
