I don't get it. The setSample methods aren't disambiguated by the types of the coordinate arguments -- there's just int int int int, int int int float, and int int int double overloads, so the exact right one should be inferrable if the final argument is known to be a double (and the WritableRaster itself is hinted). It being a primitive local double really ought to suffice, and certainly specifying that the middle arguments are ints shouldn't logically have any effect. Well, except to add a bit of overhead with three additional calls to RT.intCast that really ought to be avoidable. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
