AW: Know RGB from color index

[etchekov]

I was searching in my files - here is one more way (PLUA 1) to extract the rgb - values



function GetRGB(var)

    local qr, qg, qb

    qr=floor(var/65536)

    qg=floor((var-qr*65536)/256)

    qb=var-qr*65536-qg*256

    return qr,qg,qb

end


very best regards

Emil

Betreff: [plua] Know RGB from color index

My question is, exactly as title says, is there any way to know the R,
G and B values of a color given its index?

Thank you very much for your help, from technical to comprehensive
info - even a plua 1 solution, what i've looking for! Thanks again.

And in the function i see "return"... Is useful to know that... So i
can assign the function like any other? I've programmed for some years
in plua 1, since plua 1.0, and i didn't know about the return
clause... Hoh!
