I'll paste an excerpt of the last source I've seen from you:
def GenerateRing(x,y, N): Generates square rings around a point in data
which has 300 columns(x) and 3000 rows(y)
indices = 
for i in xrange(-N, N):
radius = .5
points = 
for cy in xrange(0, data.height):
for cx in xrange(0, data.width):
if data[cy,cx] == (0.0,0.0,0.0):
centre = data[cy, cx]
change = True
for ring_number in xrange(1, 100):
change = False
new_indices = GenerateRing(cx, cy, ring_number)
When that GenerateRing() is first called, cy will be zero, cx the same,
and ring_number will be 1.
So some of the tuples in the returned list will have negative ints. You
don't check for that either.
I still think that data.height and data.width aren't the right limits to
