Yes, but only if there are no closed loops in the skeleton (i.e. the original
shape does not have holes).
Just imagine the skeleton of a doughnut (a circle). In this case its perimeter
should be the skeleton length (and by dividing by two one will underestimate
it by half). Of course this is an extreme situation, but better be aware of
it beforehand.
I have a semi-working version of Particles8_Plus that measures lines lengths.
If anybody wants to test/validate it (with skeletons of known sizes?) let me
know.
