[GRASSLIST:538] i.composite and d.rgb

Hi all,

I want to use a color composite in order to select
signature sites. The thing is, when I create the color
composite with i.composite the colors comes too dark,
differente from when I display them with d.rgb. The 3
images used have a grey.eq color table...

Thanks

Daniel

d.rgb uses the map's colour table, i.composite doesn't.

Try using r.rescale.eq to equalise the actual category values rather
than the colour table.
