How to crop a 2D tessellation?

[mlucasq]

Hi Romain / Neper devs,

I'm using neper -T -transform 'crop(...)' to crop tessellations, and I’ve had success doing this in 3D using:

-transform 'crop(cube(xmin, xmax, ymin, ymax, zmin, zmax))'

Now I’m trying to do the same in 2D, using:

crop = "crop(square({xmin},{xmax},{ymin},{ymax}))"

But Neper throws an error (or doesn’t crop), and I couldn’t find any documentation about square(...) being supported as a crop primitive in 2D.

Questions:

1. Is there a supported way to crop a 2D tessellation using the -transform 'crop(...)' method?
2. If not, is there a workaround? (e.g. using cube(..., zmin, zmax) with a 2D tessellation in the XY plane?)

Thanks a lot!

Best,
Lucas
