10 It is possible to have whitespace between a command line option and its
12 parameter.

15 grodvi is a driver for groff that produces TeX dvi format. Normally it
16 should be run by groff -Tdvi. This will run troff -Tdvi; it will also
17 input the macros /usr/share/groff/1.18.1.4/tmac/dvi.tmac; if the input
18 is being preprocessed with eqn it will also input
19 /usr/share/groff/1.18.1.4/font/devdvi/eqnchar.
20 The dvi file generated by grodvi can be printed by any correctly-writ‐
22 ten dvi driver. The troff drawing primitives are implemented using the
23 tpic version 2 specials. If the driver does not support these, the \D
24 commands will not produce any output.
25 There is an additional drawing command available:
27 \D'R dh dv'
29 Draw a rule (solid black rectangle), with one corner at the cur‐
30 rent position, and the diagonally opposite corner at the current
31 position +(dh,dv). Afterwards the current position will be at
32 the opposite corner. This produces a rule in the dvi file and
33 so can be printed even with a driver that does not support the
34 tpic specials unlike the other \D commands.
35 The groff command \X'anything' is translated into the same command in
37 the dvi file as would be produced by \special{anything} in TeX; any‐
38 thing may not contain a newline.
39 For inclusion of EPS image files, grodvi loads pspic.tmac automati‐
41 cally, providing the PSPIC macro. Please check grops (1) for a
42 detailed description of this macro.
43 Font files for grodvi can be created from tfm files using tfmtodit(1).
45 The font description file should contain the following additional com‐
46 mands:
47 internalname name
49 The name of the tfm file (without the .tfm extension) is
50 name.
51 checksum n The checksum in the tfm file is n.
53 designsize n The designsize in the tfm file is n.
55 These are automatically generated by tfmtodit.
57 The default color for \m and \M is black. Currently, the drawing color
59 for \D commands is always black, and fill color values are translated
60 to gray.
61 In troff the \N escape sequence can be used to access characters by
63 their position in the corresponding tfm file; all characters in the tfm
64 file can be accessed this way.
65
67 -d Do not use tpic specials to implement drawing commands. Hori‐
68 zontal and vertical lines will be implemented by rules. Other
69 drawing commands will be ignored.
70 -v Print the version number.
72 -wn Set the default line thickness to n thousandths of an em. If
74 this option isn't specified, the line thickness defaults to
75 0.04 em.
76 -Fdir Prepend directory dir/devname to the search path for font and
78 device description files; name is the name of the device, usu‐
79 ally dvi.

82 There are styles called R, I, B, and BI mounted at font positions 1 to
83 4. The fonts are grouped into families T and H having members in each
84 of these styles:
85 TR CM Roman (cmr10)
87 TI CM Text Italic (cmti10)
89 TB CM Bold Extended Roman (cmbx10)
91 TBI CM Bold Extended Text Italic (cmbxti10)
93 HR CM Sans Serif (cmss10)
95 HI CM Slanted Sans Serif (cmssi10)
97 HB CM Sans Serif Bold Extended (cmssbx10)
99 HBI CM Slanted Sans Serif Bold Extended (cmssbxo10)
101 There are also the following fonts which are not members of a family:
103 CW CM Typewriter Text (cmtt10)
105 CWI CM Italic Typewriter Text (cmitt10)
107 Special fonts are MI (cmmi10), S (cmsy10), EX (cmex10), and, perhaps
109 surprisingly, TR, TI, and CW, due to the different font encodings of
110 text fonts. For italic fonts, CWI is used instead of CW.
111 Finally, the symbol fonts of the American Mathematical Society are
113 available as special fonts SA (msam10) and SB (msbm10). These two
114 fonts are not mounted by default.
115 Using the option -mec (loading the file ec.tmac) EC and TC fonts are
117 used. The design of the EC family is very similar to that of the CM
118 fonts; additionally, they give a much better coverage of groff symbols.
119 Note that ec.tmac must be called before any language-specific files; it
120 doesn't take care of hcode values.
121
123 /usr/share/groff/1.18.1.4/font/devdvi/DESC
124 Device description file.
125 /usr/share/groff/1.18.1.4/font/devdvi/F
127 Font description file for font F.
128 /usr/share/groff/1.18.1.4/tmac/dvi.tmac
130 Macros for use with grodvi.
131 /usr/share/groff/1.18.1.4/tmac/ec.tmac
133 Macros to switch to EC fonts.
134
136 Dvi files produced by grodvi use a different resolution (57816 units
137 per inch) to those produced by TeX. Incorrectly written drivers which
138 assume the resolution used by TeX, rather than using the resolution
139 specified in the dvi file will not work with grodvi.
140 When using the -d option with boxed tables, vertical and horizontal
142 lines can sometimes protrude by one pixel. This is a consequence of
143 the way TeX requires that the heights and widths of rules be rounded.
