Any way to "negatively" stroke a selection?

[marigolden]

I have a cartoon picture that came with an outline. I want to thin the outline either by making the inner color areas bigger or the outline thinner, it doesn't matter. Is it possible to some way negatively stroke a selection? I tried to put a minus sign in the pixel line width section but it just auto-set to 0.

Try this:

- Select the inside of the outline
- Select>To path, and remove the selection
- Add a transparent layer
- Edit>Stroke line and stroke with twice the required removed width, using the color inside the outline
