plugin for intersection counting

[Karolin Lange]

Hello all!

I wanted to ask if somebody knows where to find a Test line system for
intersection counting?
For example like the "isotropic curvilinear test system" of Merz,
1967(with unit square containing a hemicircle)or
the "short line multipurpose test system" of Weibel,1966

I would be grateful if you can help me.
