PostScript DISPLAY DRIVER
Table of contents
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.
