[Numpy-discussion] What protocol to use now?
Tue Dec 8 12:34:12 CST 2009
There was just a question on the wxPython list about how to optimize
some drawing of data in numpy arrays. Currently, wxPython uses
PySequenceGetItem to iterate through an array, so you can imagine there
is a fair bit of overhead in that.
But what to use?
We don't want to require numpy, so using the numpy API directly is out.
Using the buffer interface makes it too hard to catch user errors.
The array interface was made for this sort of thing, but is deprecated:
Is the new PEP 3118 protocol now (as of version 1.4) supported by numpy,
at least for export? At the moment, a one-way street is OK for this
