python-gdsii 0.2.3

Usage

For most cases interface provided by Library class from gdsii.library should be enough. Here is a small example:

from gdsii.library import Library
from gdsii.elements import *

# read a library from a file
with open('file.gds', 'rb') as stream:
    lib = Library.load(stream)

# let's move the first structure to a new library
new_lib = Library(5, b'NEWLIB.DB', 1e-9, 0.001)
struc = lib.pop(0) # libraries and structures are derived from list class
new_lib.append(struc)

# let's also add some elements...
# Note: first and last points in the boundary should be the same
#       this is required by GDSII spec.
struc.append(Boundary(45, 0, [(-100000, -100000), (-100000, 0), (0,0), (0, -100000), (-100000, -100000)]))

# Save both files with different names...
with open('newfile1.gds', 'wb') as stream:
    lib.save(stream)

with open('newfile2.gds', 'wb') as stream:
    new_lib.save(stream)
