Dear all, The names proposed seem all intuitive and improving over the old nomenclature. Nevertheless, I'd point that the expression: |(x − Xi )| + |(y − Yi )| ≤ dist actually defines a circle, not a diamond (this is obvious when dist is, say, larger than 5). And indeed it is a circle that we are expecting here. So in this particular case the method name could need some more work. On a further release of the manual some illustration of these different types of neighbourhoods, with different dist values could be helpful. Regards, Luís
