[GRASS-dev] color tables

[Helena Mitasova]

I often get a question why there aren't images of color tables in  
GRASS GUI
along with their names. Is this technically feasible? Or it is  
already there and I just
don't see it?

I am thinking about adding them to the r.colors man page, but first I  
would like to ask
whether somebody has done this already (or has a script to do it).
I was thinking about running something like this through all color  
tables

set GRASS_WIDTH=50 and GRASS_HEIGHT=100
r.colors elev co=ryg
d.colortable elev
d.out.file ryg_col
d.erase
convert -rotate 90 ryg_col
