gplugins.klayout.dataprep.regions.RegionCollection

class gplugins.klayout.dataprep.regions.RegionCollection(gdspath, cell_name: str | None = None)

A RegionCollection can load a GDS file and make layer operations on it.

It is a dictionary of layers with Region objects.

Parameters:

• gdspath – to read GDS from.

• cell_name – optional top cell name to edit (defaults to the top cell of the layout if None).

d = RegionCollection(gdspath)
d[LAYER.SLAB90] += 2 # grow slab by 2um
d[LAYER.SLAB90] -= 2 # shrink slab by 2um
d[LAYER.SLAB90].smooth(1000) # smooth slab by 1um points
d[LAYER.DEEP_ETCH] = d[LAYER.SLAB90] # copy layer
d[LAYER.SLAB90].clear() # clear slab150
d.write_gds("out.gds", keep_original=True)

__init__(gdspath, cell_name: str | None = None) → None
