Actually, numarray does support morphological array operations. See
the chapter on 'Multi-dimensional image processing
*
import numarray.nd_image as Filter
import PIL.Image as Image
im = Image.open(file_name)
array_dat = reshape(array(list(im.getdata())), im.size)
filt_array_dat = Filter.correlate(array_dat, my_filter)
et cetera...

Poking around in the PyOpenGL tarball... I can see that the wrapper
for the WGL pixel format function includes flags for rendering to a
bitmap and for hardware acceleration... so maybe I could get
hardware-accelerated off-screen rendering under win32.. but what about
linux?

Numeric.
But there's only one current, unlabeled, windows installer and there
seems to have been a change, some time back before version 0.7, in how
this question is dealt with. Can someone clarify?

The problem is that I chose an example function that's too simple.
Non-trivial functions aren't so polymorphic, unfortunately.

I can change that and everything else stays the same. However, I

a GeoTIFF file with PIL means poking
around in the PIL TIFF plugin file which I'm a little wary of doing.
Also, I don't see any clear description in the PIL documentation on
how to add specified TIFF keys to a saved file. Any words of wisdom
about either of these questions would be much
my purposes. If a couple
of lines of Python added to what I've already got will do the job, I'd
rather do that then compile and learn yet another API.
