PostScript DISPLAY DRIVER

Table of contents

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:

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.
