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	 mono-
	      chrome.
	      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,	multi-
       ply  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.
