Is np.invert(intwave) an XOR operation?

[Jyny]

I'm look at invert function in rattlesnake.py https://github.com/loehnertz/rattlesnake/blob/master/rattlesnake.py#L312

according to numpy document np.invert is a bitwise NOT operation https://numpy.org/doc/stable/reference/generated/numpy.invert.html

this confuse me what the relation between two operation here?
