Which Python version? Under Python 3 this should probably happen automatically, try: cdef object[int, ndim=1, mode="c"] arr = yourarray Not sure about Python 2.6+ For Python 2.5- an array.pxd must be written. It is not difficult, one simply follows the pattern in numpy.pxd (by implementing __getbuffer__ and filling in the Py_buffer struct). If somebody ends up doing this, please submit it for inclusion in Python. Here's some docs: http://wiki.cython.org/docs/specialmethods http://wiki.cython.org/enhancements/buffer http://docs.python.org/c-api/buffer.html > Similar Question regarding a good way of using PIL images directly > (without copying) ? Are there examples? I don't think so. I believe the story is the same (one must make an Image.pxd implementing __getbuffer__ on the behalf of PIL). However IIRC the "full" mode must be used (i.e. images are stored as arrays of pointers to arrays), so it is slightly more complicated to get the details rest. -- Dag Sverre _______________________________________________ Cython-dev mailing list [email protected] http://codespeak.net/mailman/listinfo/cython-dev
