Hi, Can anyone explain to me how to get the four values from the imlib2 egg procedure (imlib:pixel/rgba img x y)? It seems to only return the first value, but it's supposed to return four values.

That's the problem, I don't know what to use.I've tried call-with-values and receive, but both give me errors, mostly because I have no idea what I'm doing.Receive expects (name1 name2 ...) valexp body, but this produces an error since name1 is not a command.
