PostScript DISPLAY DRIVER

6       PS display driver to create PostScript files.
7

DESCRIPTION

9       The PS driver generates a PostScript file from GRASS display commands.
10

USAGE

12   Environment variables
13       The  PS  driver  can be enabled by setting GRASS_RENDER_IMMEDIATE vari‐
14       able, eg.
15       export GRASS_RENDER_IMMEDIATE=ps
16       Several environment variables affect the operation of the PS driver:
17
18           •   GRASS_RENDER_WIDTH=xxx
19               the width of the image map (default is 640).
20
21           •   GRASS_RENDER_HEIGHT=yyy
22               the height of the image map (default is 480).
23
24           •   GRASS_RENDER_TRUECOLOR=[TRUE|FALSE]
25               sets true-color support. Default is FALSE.
26
27           •   GRASS_RENDER_FILE
28               name of output file. If it ends with ".eps" an EPS file will be
29               created.
30
31           •   GRASS_RENDER_PS_PAPER
32               sets  the screen dimensions and margins to fit a standard paper
33               size, see also GRASS_RENDER_WIDTH, GRASS_RENDER_HEIGHT.
34
35           •   GRASS_RENDER_PS_LANDSCAPE
36               if TRUE, the screen is rotated 90 degrees counter-clockwise  so
37               that a "landscape" screen fits better on "portrait" paper.
38
39           •   GRASS_RENDER_PS_HEADER
40               if  FALSE,  the output is appended to any existing file, and no
41               prolog or setup sections are generated.
42
43           •   GRASS_RENDER_PS_TRAILER
44               if FALSE, no trailer section is generated.
45
46   Example
47       export GRASS_RENDER_IMMEDIATE=ps
48       export GRASS_RENDER_TRUECOLOR=TRUE
49       g.region raster=elevation
50       d.rast elevation
51       d.vect roadsmajor color=red
52       This writes a file named map.ps in your current directory.
53

NOTES

55       The resolution of the output files is defined  by  current  region  ex‐
56       tents.  Use  g.region -p to get the number of rows and cols and use the
57       environment variables to set the image size. If you would like a larger
58       image, multiply both rows and cols by the same whole number to preserve
59       the aspect ratio.
60
61       GRASS_RENDER_TRUECOLOR requires either PostScript level 2  or  level  1
62       plus  the  colorimage  and  setrgbcolor operators (this is the case for
63       colour printers which pre-date level 2 PostScript).
64
65       Masked images (d.rast, d.rgb, d.his -n) require PostScript level 3.
