- raster=name
- Name of input raster map to generate legend from
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.
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.
In this example, the polar diagram of the 'aspect' angle map in the
North Carolina sample dataset is generated:
g.region raster=landclass96 -p
d.rast.leg landclass96
