GRODVI(1)GRODVI(1)NAMEgrodvi - convert groff output to TeX dvi format
SYNOPSISgrodvi [ -dv ] [ -wn ] [ -Fdir ] [ files... ]
It is possible to have whitespace between a command line option and its
parameter.
DESCRIPTIONgrodvi is a driver for groff that produces TeX dvi format. Normally it
should be run by groff -Tdvi. This will run gtroff -Tdvi; it will also
input the macros /freeware/gnu-tools/share/groff/1.17.2/tmac/dvi.tmac;
if the input is being preprocessed with geqn it will also input /free‐
ware/gnu-tools/share/groff/1.17.2/font/devdvi/eqnchar.
The dvi file generated by grodvi can be printed by any correctly-writ‐
ten dvi driver. The troff drawing primitives are implemented using the
tpic version 2 specials. If the driver does not support these, the \D
commands will not produce any output.
There is an additional drawing command available:
\D'R dh dv'
Draw a rule (solid black rectangle), with one corner at the cur‐
rent position, and the diagonally opposite corner at the current
position +(dh,dv). Afterwards the current position will be at
the opposite corner. This produces a rule in the dvi file and
so can be printed even with a driver that does not support the
tpic specials unlike the other \D commands.
The groff command \X'anything' is translated into the same command in
the dvi file as would be produced by \special{anything} in TeX; any‐
thing may not contain a newline.
Font files for grodvi can be created from tfm files using tfmtodit(1).
The font description file should contain the following additional com‐
mands:
internalname name
The name of the tfm file (without the .tfm extension) is
name.
checksum n The checksum in the tfm file is n.
designsize n The designsize in the tfm file is n.
These are automatically generated by tfmtodit.
In troff the \N escape sequence can be used to access characters by
their position in the corresponding tfm file; all characters in the tfm
file can be accessed this way.
OPTIONS-d Do not use tpic specials to implement drawing commands. Hori‐
zontal and vertical lines will be implemented by rules. Other
drawing commands will be ignored.
-v Print the version number.
-wn Set the default line thickness to n thousandths of an em.
-Fdir Prepend directory dir/devdvi to the search path for font and
device description files.

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