more general filtering (e.g. band pass filters)

[apatlpo]

I've got the feeling this is not implemented yet, while scipy.signal.firwin allows in principle.
Does anybody confirm?

Yes, you can only do a low-pass filtering for the moment. I usually estimate the high-pass component by subtracting the low-pass component to the original field. Implementing high-pass filtering would just require to set 1 - low-pass kernel. The band-pass would require to make a composition of a high-pass and a low pass-kernel. Feel free to modify the code in xscale.window.linearfilters.Window.set and submit a pull request if you want this functionality added to xscale.

hi Guillaume, how about a lanczos "window" like you had added in oocgcm?
