Compute always works on the 'data' component so with your
Print("rd"), tell it to only print the 'data' component. This will
help limit what you are looking at in the message window. So the
order of the modules to use the colors for data is Mark -> Compute ->
Print.

Hi David,
Ok, but how do I display the output from the Compute module? I tried
using Display or Print ("rd"), yet I cannot tell where the computations
end up?
Thanks for your help,
Kelly

Images do not necessarily have data. When they are Imported, they
have colors. If you "Mark" colors, then the colors become the 'data'
component and you can work on them. You may then want to "Compute"
with an expression of a.0 to extract only one of the colors from the
3-vector color component.
