NAME¶
PS driver - driver to create PostScript files.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 driverNOTES¶
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, 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.SEE ALSO¶
