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.
Why not just return a list and make it simple?
The call to (imlib:pixel img x y) should return the r, g, b, a values
of the
pixel. Just calling it produces r. The others are there, but how do
I get
them?
confused....

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. This may be more of a scheme
question than an imlib2 question, but either way I can't seem to get it
to work.
Are you using RECEIVE or LET-VALUES?
Cheers,
