Thank you Stefan and Anne for such quick replies.
I am writing a gimp plugin, and if anybody is interested in how do that --
there are only about 10-20 examples that I"ve found -- this plugin is
attempting to do raster-to-vector conversion on the bluest pixels. It outputs

Hi all,
The generalised ufuncs branch was made available before SciPy'08. We
solicited comments on its implementation and structuring, but received
very little feedback. Unless there are any further comments from the
community, I propose that we merge it.
It is unfortunate that we have so many

Are you sure you have numpy installed ? What version do you have ?

Howdy,
I'm trying to run some scripts associated with a paper I was reading. They use
the matplotlib to generate figures which in turn calles numpy. I'm new to
python, but I'm very familiar with perl. I'm getting the following error, and
I'm not quite sure what is causing it. Can anyone here offer
Hi,
I have this silly color filter that Stefan gave me:
def vanderwalt(image, f):
"""colorfilter, thanks to Stefan van der Walt"""
RED, GRN, BLU = 0, 1, 2
bluemask = (image[...,BLU] > f*image[...,GRN]) & \
(image[...,BLU] > f*image[...,RED])
return bluemask
