RGB from 3 grayscale images under IDL [message #6790]

Hi all,

I've got three seperate grayscale images that i'd like to combine
to form a RGB color image. This is easily done in ENVI when loading
the file but under IDL it is not as obvious. Or is it?

three 300x300 arrays (8bit)

I started out with

image=byarr(300,300,3) ; define a single array
read_gif,'red.gif',image(0)
read_gif,'blue.gif',image(1)
read_gif,'green.gif',image(2)

Here's where I'm stuck. What parameters need I use to display
this as a RGB with TV? Is there a better/easier way to go about
this?

Thanks,
Scott
