DESCRIPTION

d.rast.leg is a GRASS script which clears the entire screen, divides it into a main (left) and a minor (right) frames, and then displays a raster map in the main frame and the map legend in the minor frame. The main frame remains active when the program finishs.

NOTES

The legend may be flipped with the -f flag.

If the num_of_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 num_of_lines minus 1 categories with the rest being truncated.

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

The user may specify a second raster map with the rast 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".
