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.
