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
  - 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
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.
