#1732: r.colors feature request (add flag to copy categories without having to run
r.category separately)

Often times when I use the r.colors function to copy colors from an
existing rater color table, I repeat the process using the r.category
function to copy the associated categories.

It would be nice to have a flag in r.colors that allows the user to copy
the categories at the same time from the selected raster layer instead of
having to run r.colors and r.category separately.

Changes (by hamish):

  * keywords: => r.colors, r.category
  * version: unspecified => svn-trunk
  * cpu: Unspecified => All

Comment:

I suggest this is best dealt with using a wrapper script, rather than
adding cat label support to r.colors and color support to r.cats, etc., ad
infinitum.

regards,
Hamish

Comment(by hamish):

maybe adding an option to copy-everything from another raster to
r.support?

Comment(by neteler):

There is also r.colors.out in GRASS 7.

You question is a bit unclear (to me), any use case?
