6 PS driver - driver to create PostScript files
7 (drivers)
8
10 The PS driver generates a PostScript file from GRASS display commands.
11 The driver is started as 'pseudo' monitor (PS file instead) and when
12 stopped, all output from previously used display commands are written
13 to the PostScript file.
14
16 Environment variables
17 Several environment variables effect the operation of the PS driver:
18
19 GRASS_PSFILE
20 name of output file. If it ends with ".eps" an EPS file will be cre‐
21 ated.
22
23 GRASS_PAPER
24 sets the screen dimensions and margins to fit a standard paper size,
25 see also GRASS_WIDTH, GRASS_HEIGHT.
26
27 GRASS_WIDTH
28 defines the width of the screen, see also GRASS_HEIGHT
29
30 GRASS_HEIGHT
31 defines the height of the screen, see also GRASS_WIDTH
32
33 GRASS_TRUECOLOR
34 if "TRUE", the PS driver generates color output, otherwise mono‐
35 chrome.
36
37 GRASS_LANDSCAPE
38 if "TRUE", the screen is rotated 90 degrees counter-clockwise so that
39 a "landscape" screen fits better on "portrait" paper.
40
41 GRASS_PS_HEADER
42 if "FALSE", the output is appended to any existing file, and no pro‐
43 log or setup sections are generated.
44
45 GRASS_PS_TRAILER
46 if "FALSE", no trailer section is generated.

48 Example
49
50 d.mon start=PS
51 Display raster map and vector polygons
52
53 d.rast somerastermap
54 d.vect map=somevectormap color=red
55 Stop the driver subsequently. This will write a file named map.ps to
56 be created in your current directory:
57 d.mon stop=PS
58
59
61 The resolution of the PS raster map is defined by the map extents. Use
62 g.region -p to get the number of rows and cols and use the environment
63 variables to set the PS size. If you would like a larger image, multi‐
64 ply both rows and cols by the same whole number to preserve the aspect
65 ratio.
66
67 GRASS_TRUECOLOR requires either PostScript level 2 or level 1 plus the
68 colorimage and setrgbcolor operators (this is the case for colour
69 printers which pre-date level 2 PostScript).
70
71 Only masked images (d.rast -o, d.rgb -o, d.his -n) require PostScript
72 level 3.
