    Hi,
    I've had an import error with some of my code, specifically with
    nxutils (I need
    it for using points_inside_poly).

    In [1]: import matplotlib.nxutils as nx
    ---------------------------------------------------------------------------
    ImportError                               Traceback (most recent
    call last)
    /home/jscandal/<ipython-input-1-c56b9729b42e> in <module>()
    ----> 1 import matplotlib.nxutils as nx

    ImportError: No module named nxutils

    I built mpl from trunk and tried also version 1.1 from my distro,
    but neither
    seems to have nxutils. I still find the examples in the docs using
    it, though,
    so I am confused.
    Has nxutils been replaced or removed?

    Thanks

    Jorge


Last I heard, it was supposed to be deprecated in master (although it 
was accidentially removed at one point).  Indeed, it appears to be 
missing from the current master.  The deprecation process must be 
followed! Personally, I think such removal is short-sighted (nxutil's 
functions are much faster than their python counter-parts).
I agree that the deprecation process should have been followed better.  
However, I'm not sure what you mean by them being faster than their 
Pyhton counterparts.  Both functions in nxutils are replaced by 
functions in _path.cpp, which are also written in C++ but are more 
complete and don't have broken corner cases.  They may be slightly 
slower  because they have a few more checks and handle Bezier curves, 
but they are not significantly slower.
