Alright, it looks like it is working now. Here is what I did to rebuild
and re-install PIL from scratch:
# rm -rf /usr/local/lib/python2.7/site-packages/PIL*
# rm -rf /src/Imaging-1.1.7
# cd /src
# tar -xvzf Imaging-1.1.7.tar.gz
# cd Imaging-1.1.7
# python2.7 setup.py build_ext -i
# python2.7
This uses numpy, for a centroid algorithm you can do this:
data is your array of values within the box
ul means upper left of your box
xind = ul[1]+np.indices(np.shape(data))[1]
yind = ul[0]+np.indices(np.shape(data))[0]
x = (xind*data).sum()/float(data.sum())
y =

or via Mercurial, from https://bitbucket.org/effbot/pil-2009-raclette
I've decided to abandon the planned 1.1.8 release, including the rough
and still unreleased 3.X

Is there any doc that describes what does or doesn't work under 3.X?
