TypeError: unsupported operand type(s) for <<: 'float' and 'int'

awesome repo!!

I am getting the above error when running a fairly large and complex concave polygon with a hole ( full trace is below ).

updating lines 455 and 456 to force the result to an int seems to be sufficient
x = int(32767 * (x - minX) // size)
y = int(32767 * (y - minY) // size)

Hi @RoboDonut,
can you provide by any chance the data you've used when getting this error?

Yep, had the same issue and using int(32767 * (x - minX) // size) resolved it. The // operator doesn't give an int when one of the operators is a float it seems.

@js-on
i think this was the file i was working with at the time
alabama_smsa.zip

Hey, is this poblem also in the Pypi released version? If yes, please checkout this issue - #1 (comment)
