Hi Ian,
ok, I looked at the PyX source code now. Apparently it now wants three
arguments (none of which are optional now), so it should be something like
para.normpath_selfintersections(mypath.normpath(), 0.01, 0.01)
assuming that the eps_comparepairs should be similar to the epsilon.
Hopefully that works.
Best,
Georg
