Awesome functionality, thanks a lot for the pointer!
That actually already answers the second question that I had: how to
convert text to curves ;)
(I was at a fab lab earlier today and the initial text (from
lmt_followtext) did not come through before, while this does.)
But now I have the third question: how can I avoid changing text size,
so that it does NOT fit the full length of the curve, but use a
consistent size instead?
I can of course shorten the curve and only keep an arc, but I would
like to typeset 20 different words on an arc while keeping the font
size consistent.
Thanks a lot,
Mojca
