I have three 2-D images chan01,chan02 and chan03. For some reason, I
can get a pretty picture if I do like this
IDL> tv,chan01 & tv,chan02,chan=2 & tv,chan03,chan=3
But if I just use "tv,
reform([[chan01],[chan02],]chan03]],3000,3000,3),true=3", the image in
chan01 is barely to be seen. The only thing bother me is that it seems
to me that the postscript (even z-buffer?) doesn't allow channel. And
I don't want to first draw on direct graphic window, then read out the
image and write to a ps file, which will reduce the resolution. Is
there other wasy to work around? Thanks!
