Sorry again... this should be

ESF[ (x*4) + (Distance(Pixel[x][y], Centroid[y]) * 4) % 1) += ...

i.e. I should multiply the distance from the edge center by 4, and then take only the fractionary part.

This way, if the pixel is an integer number of pixels away from the edge center, it will end up in the "first bin";
if it's an integer number of pixels away, plus 0.25, it will end up in the "second bin", and so on.


I hope this time I've got it right :-)
