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 effect 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  environ-
       ment  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.
