Thanks very much for your response Martin but I don't understand it. I don't
have three vars called R G and B. I just have a number which was retuned
from getPixel. Am I being stupid? I can't see how I should do what you
sugest. Pease explain a little further.

to go from a 24 bit number to 3x8 bit colour components you can just shift
it
and mask the bits you need :
var r=color 16 0xFF
var g=color 8 0xFF
var b=color 0xFF
that should do the job.

Hi Guys,
I'm having some problems with getting the brightness of a color returned
from get pixel. get pixel returns an RGB color as a number which means I
was
expecting something like three groups of three numbers 255 255 255 or
similar. what I am actually getting back is of this form 14540754 one
digit
short.
