description
grodvi
is a driver for groff that produces TeX dvi format.
Normally it should be run by groff -Tdvi.
This will run troff -Tdvi; it will also
input the macros in
/usr/share/groff/1.22.1/tmac/dvi.tmac.
The dvi file
generated by grodvi can be printed by any
correctly-written 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 current 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;
anything may not contain a newline.
For inclusion
of EPS image files, -Tdvi loads
pspic.tmac automatically, providing the PSPIC
macro. Please check groff_tmac(5) for a detailed
description.
Font files for
grodvi can be created from tfm files using
tfmtodit(1). The font description file should contain
the following additional commands:
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.
The default
color for \m and \M is black. Currently, the
drawing color for \D commands is always black, and
fill color values are translated to gray.
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.
By design, the
DVI format doesn’t care about physical dimensions of
the output medium. Instead, grodvi emits the
equivalent to TeX’s
\special{papersize=width,length}
on the first page; dvips (and possibly other DVI
drivers) then sets the page size accordingly. If either the
page width or length is not positive, no papersize special
is output.
options
-d
Do not use tpic specials to
implement drawing commands. Horizontal and vertical lines
will be implemented by rules. Other drawing commands will be
ignored.
-Fdir
Prepend directory dir/devname to
the search path for font and device description files;
name is the name of the device, usually
dvi.
-l
Specify landscape orientation.
-ppapersize
Specify paper dimensions. This
overrides the papersize, paperlength, and
paperwidth commands in the DESC file; it
accepts the same arguments as the papersize command
(see groff_font(5) for details).
-v
Print the version number.
-wn
Set the default line thickness to n thousandths
of an em. If this option isn’t specified, the line
thickness defaults to 0.04 em.

Special fonts are MI (cmmi10), S (cmsy10),
EX (cmex10), SC (cmtex10, only for CW), and,
perhaps surprisingly, TR, TI, and CW, due to
the different font encodings of text fonts. For italic fonts,
CWI is used instead of CW.
Finally, the symbol fonts of the American Mathematical Society
are available as special fonts SA (msam10) and SB
(msbm10). These two fonts are not mounted by default.
Using the option -mec (which loads the file
ec.tmac) provides the EC and TC fonts. The design of the
EC family is very similar to that of the CM fonts; additionally,
they give a much better coverage of groff symbols. Note that
ec.tmac must be called before any language-specific files;
it doesn’t take care of hcode values.

There are also the following fonts which are not members of a
family:
usage
There are styles called R, I, B, and
BI mounted at font positions 1 to 4. The fonts are
grouped into families T and H having members
in each of these styles:
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.
