NAME

   d.rast.num   -  Overlays cell category values on a raster map displayed
   in the active graphics frame.

KEYWORDS

   display, map annotations, raster

SYNOPSIS

   d.rast.num
   d.rast.num --help
   d.rast.num  [-af]   map=name    [text_color=name]     [grid_color=name]
   [precision=integer]    [font=string]    [path=name]    [charset=string]
   [--help]  [--verbose]  [--quiet]  [--ui]

   Flags:
   -a
       Align grids with raster cells

   -f
       Get text color from cell color value

   --help
       Print usage summary

   --verbose
       Verbose module output

   --quiet
       Quiet module output

   --ui
       Force launching GUI dialog

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

   text_color=name
       Text color
       Either a standard color name or R:G:B triplet
       Default: black

   grid_color=name
       Grid color
       Either a standard color name, R:G:B triplet, or "none"
       Default: gray

   precision=integer
       Number of significant digits (floating point only)
       Options: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
       Default: 1

   font=string
       Font name

   path=name
       Path to font file

   charset=string
       Text encoding (only applicable to TrueType fonts)

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".

EXAMPLE

   A) Distance from the streams network (North Carolina sample dataset):
   g.region raster=streams_derived -p
   r.grow.distance input=streams_derived distance=dist_from_streams
   d.rast.num dist_from_streams -a
   Euclidean  distance from the streams network in meters (detail, numbers
   shown with d.rast.num)
