gdstk.read_gds

gdstk.read_gds(infile, unit=0, tolerance=0, filter=None) → gdstk.Library

Import a library from a GDSII stream file.

Parameters:

  • infile (str or pathlib.Path) – Name of the input file.

  • unit (number) – If greater than zero, convert the imported geometry to the this unit.

  • tolerance (number) – Default tolerance for loaded paths. If zero or negative, the library rounding size is used (precision / unit).
