export GRASS_RENDER_IMMEDIATE=ps
TRUE, the screen is rotated 90 degrees
counter-clockwise so that a "landscape" screen fits better on
"portrait" paper.
FALSE, the output is appended to any existing file,
and no prolog or setup sections are generated.
FALSE, no trailer section is generated.
export GRASS_RENDER_IMMEDIATE=ps export GRASS_RENDER_TRUECOLOR=TRUE g.region raster=elevation d.rast elevation d.vect roadsmajor color=red
map.ps in your current directory.
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.
