       --quiet
           Quiet module output

       --ui
           Force launching GUI dialog

   Parameters:
       map=name [required]
           Name of raster map to display

       lines=integer
           Number of lines to appear in the legend

       raster=name
           Name of input raster map to generate legend from

DESCRIPTION

       d.rast.leg shows a raster map along with its legend.  It first clears the  entire  screen,
       then  divides  it into a main (left) and a minor (right) frames, and displays a raster map
       in the main frame and the map legend in the minor frame. The  main  frame  remains  active
       when the program finishes.

NOTES

       The legend may be flipped with the -f flag.

       If  the  lines  parameter is not given then the legend frame will display as many lines as
       number of categories in the map, otherwise, it  will  display  the  first  lines  minus  1
       categories with the rest being truncated.

       The  user  may  adjust  the  lines  parameter  or  the  size  of graphics window to get an
       appropriate result.

       The user may specify a second raster map with the raster parameter from which  the  legend
       is  generated.  This  is  useful  to  visualize (time) series of raster maps with a common
       static legend instead of the default dynamic legend.

       To remove all frames when clearing the display, use d.erase -f.

EXAMPLE

       In this example, the polar diagram of the ’aspect’ angle map in the North Carolina  sample
       dataset location is generated:
       g.region raster=landclass96 -p
       d.rast.leg landclass96
