I see what you're suggesting, a thickener/thinner tool that takes a
parameter from the background. That would be nice to have, but for
the first cut of a complex scene it would require going over the
whole thing in a manner that seems a bit like busy work to me. I
think you could thicken/thin all the selected paths using a
background and some threshold/gamma/radius type parameters. Then
fine tune it either with the existing thickener/thinner tool or a
background sensitive thickener/thinner tool like the one you're
Do you use a graphics tablet? I'm thinking of getting one, but
right now I only use a mouse, and I find the whole calligraphy /
engraving area kind of futzy with a mouse, I suspect it's quicker /
easier with a pen. Also I wonder if there'd be performance issues
with the approach you're suggesting, in terms of how fast the tool
is moved over the area of interest and how well the machine can keep
up with altering the paths - that wouldn't be an issue with the less

Thinking more about it I agree, other places where I was thinking
you might use it there are more efficient ways.
