Hi,

Is it possible to take two FlatFields representing rgba values and combine 
them using alpha composition into a third FlatField?

e.g. f1(r, g, b, a) + f2(r, g, b, a) --> f3(r, g, b, a) ?

This could be computed manually, but is there Visad method for doing this 
sort of thing?

thanks,

Brad Buchsbaum
