NAME

        PS driver - driver to create PostScript files.
       (drivers)

DESCRIPTION

       The PS driver generates a PostScript file from GRASS display commands.  The driver is started as 'pseudo'
       monitor  (PS file instead) and when stopped, all output from previously used display commands are written
       to the PostScript file.

USAGE

   Environment variables
       Several environment variables affect the operation of the PS driver:
              GRASS_PSFILE
              name of output file. If it ends with ".eps" an EPS file will be created.
              GRASS_PAPER
              sets the screen dimensions and margins to  fit  a  standard  paper  size,  see  also  GRASS_WIDTH,
              GRASS_HEIGHT.
              GRASS_WIDTH
              defines the width of the screen, see also GRASS_HEIGHT
              GRASS_HEIGHT
              defines the height of the screen, see also GRASS_WIDTH
              GRASS_TRUECOLOR
              if TRUE, the PS driver generates color output, otherwise monochrome.
              GRASS_LANDSCAPE
              if  TRUE,  the  screen  is  rotated 90 degrees counter-clockwise so that a "landscape" screen fits
              better on "portrait" paper.
              GRASS_PS_HEADER
              if FALSE, the output is appended to any existing  file,  and  no  prolog  or  setup  sections  are
              generated.
              GRASS_PS_TRAILER
              if FALSE, no trailer section is generated.

   Example
       Start up the driver
       d.mon start=PS
        Display raster map and vector polygons
       d.rast somerastermap
       d.vect map=somevectormap color=red
         Stop  the  driver  subsequently.  This  will  write  a  file named map.ps to be created in your current
       directory:
       d.mon stop=PS

NOTES

       The resolution of the PS raster map is defined by the map extents. Use g.region -p to get the  number  of
       rows  and  cols  and  use the environment variables to set the PS size. If you would like a larger image,
       multiply both rows and cols by the same whole number to preserve the aspect ratio.

       GRASS_TRUECOLOR requires either PostScript level 2  or  level  1  plus  the  colorimage  and  setrgbcolor
       operators (this is the case for colour printers which pre-date level 2 PostScript).

       Only masked images (d.rast -o, d.rgb -o, d.his -n) require PostScript level 3.
