DESCRIPTION

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 in /usr/share/groff/1.22.2/tmac/dvi.tmac.
18
19       The dvi file generated by grodvi can be printed by any  correctly-writ‐
20       ten dvi driver.  The troff drawing primitives are implemented using the
21       tpic version 2 specials.  If the driver does not support these, the  \D
22       commands will not produce any output.
23
24       There is an additional drawing command available:
25
26       \D'R dh dv'
27              Draw a rule (solid black rectangle), with one corner at the cur‐
28              rent position, and the diagonally opposite corner at the current
29              position  +(dh,dv).   Afterwards the current position will be at
30              the opposite corner.  This produces a rule in the dvi  file  and
31              so  can  be printed even with a driver that does not support the
32              tpic specials unlike the other \D commands.
33
34       The groff command \X'anything' is translated into the same  command  in
35       the  dvi  file  as would be produced by \special{anything} in TeX; any‐
36       thing may not contain a newline.
37
38       For inclusion of EPS image files, -Tdvi loads pspic.tmac automatically,
39       providing  the  PSPIC macro.  Please check groff_tmac(5) for a detailed
40       description.
41
42       Font files for grodvi can be created from tfm files using  tfmtodit(1).
43       The  font description file should contain the following additional com‐
44       mands:
45
46       internalname name
47                     The name of the tfm file (without the .tfm extension)  is
48                     name.
49
50       checksum n    The checksum in the tfm file is n.
51
52       designsize n  The designsize in the tfm file is n.
53
54       These are automatically generated by tfmtodit.
55
56       The default color for \m and \M is black.  Currently, the drawing color
57       for \D commands is always black, and fill color values  are  translated
58       to gray.
59
60       In  troff  the  \N  escape sequence can be used to access characters by
61       their position in the corresponding tfm file; all characters in the tfm
62       file can be accessed this way.
63
64       By design, the DVI format doesn't care about physical dimensions of the
65       output medium.  Instead, grodvi emits the  equivalent  to  TeX's  \spe‐
66       cial{papersize=width,length}  on  the  first  page; dvips (and possibly
67       other DVI drivers) then sets the page size accordingly.  If either  the
68       page width or length is not positive, no papersize special is output.
69

OPTIONS

71       -d     Do  not  use tpic specials to implement drawing commands.  Hori‐
72              zontal and vertical lines will be implemented by  rules.   Other
73              drawing commands will be ignored.
74
75       -Fdir  Prepend  directory  dir/devname  to the search path for font and
76              device description files; name is the name of the  device,  usu‐
77              ally dvi.
78
79       -l     Specify landscape orientation.
80
81       -ppapersize
82              Specify  paper dimensions.  This overrides the papersize, paper‐
83              length, and paperwidth commands in the DESC file; it accepts the
84              same  arguments  as the papersize command (see groff_font(5) for
85              details).
86
87       -v     Print the version number.
88
89       -wn    Set the default line thickness to n thousandths of  an  em.   If
90              this  option  isn't  specified,  the  line thickness defaults to
91              0.04 em.
92

USAGE

94       There are styles called R, I, B, and BI mounted  at  font  positions  1
95       to 4.   The  fonts  are grouped into families T and H having members in
96       each of these styles:
97
98              TR     CM Roman (cmr10)
99              TI     CM Text Italic (cmti10)
100              TB     CM Bold Extended Roman (cmbx10)
101              TBI    CM Bold Extended Text Italic (cmbxti10)
102              HR     CM Sans Serif (cmss10)
103              HI     CM Slanted Sans Serif (cmssi10)
104              HB     CM Sans Serif Bold Extended (cmssbx10)
105              HBI    CM Slanted Sans Serif Bold Extended (cmssbxo10)
106
107       There are also the following fonts which are not members of a family:
108
109              CW     CM Typewriter Text (cmtt10)
110              CWI    CM Italic Typewriter Text (cmitt10)
111
112       Special fonts are MI (cmmi10), S (cmsy10), EX  (cmex10),  SC  (cmtex10,
113       only  for  CW),  and,  perhaps surprisingly, TR, TI, and CW, due to the
114       different font encodings of text fonts.  For italic fonts, CWI is  used
115       instead of CW.
116
117       Finally,  the  symbol  fonts  of  the American Mathematical Society are
118       available as special fonts SA (msam10)  and  SB  (msbm10).   These  two
119       fonts are not mounted by default.
120
121       Using  the  option  -mec (which loads the file ec.tmac) provides the EC
122       and TC fonts.  The design of the EC family is very similar to  that  of
123       the  CM  fonts; additionally, they give a much better coverage of groff
124       symbols.  Note that ec.tmac must be called before any language-specific
125       files; it doesn't take care of hcode values.

BUGS

147       Dvi  files  produced  by grodvi use a different resolution (57816 units
148       per inch) to those produced by TeX.  Incorrectly written drivers  which
149       assume  the  resolution  used  by TeX, rather than using the resolution
150       specified in the dvi file will not work with grodvi.
151
152       When using the -d option with boxed  tables,  vertical  and  horizontal
153       lines  can  sometimes  protrude by one pixel.  This is a consequence of
154       the way TeX requires that the heights and widths of rules be rounded.
