cad/py-gdstk - The NetBSD Packages Collection

Gdstk (GDSII Tool Kit) is a C++/Python library for creation and manipulation
of GDSII and OASIS files. It is also available as a Python module meant to be
a successor to Gdspy.

Key features for the creation of complex CAD layouts are included:

-  Boolean operations on polygons (AND, OR, NOT, XOR) based on clipping
   algorithm
-  Polygon offset (inward and outward rescaling of polygons)
-  Efficient point-in-polygon solutions for large array sets

Typical applications of Gdstk are in the fields of electronic chip design,
planar lightwave circuit design, and mechanical engineering.
