PostScript DISPLAY DRIVER

       PS display driver to create PostScript files.

DESCRIPTION

       The PS driver generates a PostScript file from GRASS display commands.

USAGE

   Environment variables
       The PS driver can be enabled by setting GRASS_RENDER_IMMEDIATE variable, eg.
       export GRASS_RENDER_IMMEDIATE=ps
       Several environment variables affect the operation of the PS driver:

           •   GRASS_RENDER_WIDTH=xxx
               the width of the image map (default is 640).

           •   GRASS_RENDER_HEIGHT=yyy
               the height of the image map (default is 480).

           •   GRASS_RENDER_TRUECOLOR=[TRUE|FALSE]
               sets true-color support. Default is FALSE.

           •   GRASS_RENDER_FILE
               name of output file. If it ends with ".eps" an EPS file will be created.

           •   GRASS_RENDER_PS_PAPER
               sets the screen dimensions and margins to fit a standard paper size, see also GRASS_RENDER_WIDTH,
               GRASS_RENDER_HEIGHT.

           •   GRASS_RENDER_PS_LANDSCAPE
               if  TRUE,  the  screen  is rotated 90 degrees counter-clockwise so that a "landscape" screen fits
               better on "portrait" paper.

           •   GRASS_RENDER_PS_HEADER
               if FALSE, the output is appended to any existing file,  and  no  prolog  or  setup  sections  are
               generated.

           •   GRASS_RENDER_PS_TRAILER
               if FALSE, no trailer section is generated.

   Example
       export GRASS_RENDER_IMMEDIATE=ps
       export GRASS_RENDER_TRUECOLOR=TRUE
       g.region raster=elevation
       d.rast elevation
       d.vect roadsmajor color=red
       This writes a file named map.ps in your current directory.

NOTES

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

       GRASS_RENDER_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).

       Masked images (d.rast, d.rgb, d.his -n) require PostScript level 3.
