invalid initialization

[llorz]

Hi Botffy,

Thanks for your great work.

I have a very quick question: I was trying to use your code to generate a straight skeleton for the following outline:
poly = [(36.88, 343.19), (36.88, 161.06), (115.81, 161.06), (115.81, 137.2), (184.98, 137.2), (184.98, 6.1279), (282.67, 6.1279), (282.67, 386.26), (163.67, 386.26), (163.67, 343.19)]

Here is how the output skeleton looks like:

i.e., no inside skeleton was computed. But I feel the input outline is valid. I am not sure what is wrong. Can you please help to check in this case?

Thanks a lot!
