DESCRIPTION

       d.rast.num overlays cell category values onto a  raster  map  layer  displayed  on  the  user's  graphics
       monitor.   Category  values  will  be displayed in the text color given and scaled to fit within a single
       cell. A grid outlining each map cell will also be overlain in a user-specified color, unless it has  been
       set to "none".

       If  no  grid  color is given the default will be used. If no map layer is specified, the program will use
       whatever raster map layer is currently displayed in the active frame on the graphics monitor.

       If the -f flag is given the displayed number will take on the color of the base map in that cell.

NOTES

       The user is advised to set the current region to a relatively small area (i.e., less than 100 rows by 100
       columns); otherwise, the individual cells being displayed will be small and the category value associated
       with each will be difficult to see.  No data cells are indicated with "Null".
