### Description

```GRODVI(1)                   General Commands Manual                  GRODVI(1)

NAME
grodvi - convert groff output to TeX dvi format

SYNOPSIS
grodvi [ -dlv ] [ -Fdir ] [ -ppapersize ] [ -wn ] [ files... ]

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

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/1.22.3/tmac/dvi.tmac.

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.

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 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.

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 \spe-
cial{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.  Hori-
zontal 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, usu-
ally dvi.

-l     Specify landscape orientation.

-ppapersize
Specify paper dimensions.  This overrides the papersize, paper-
length, 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.

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:

TR     CM Roman (cmr10)
TI     CM Text Italic (cmti10)
TB     CM Bold Extended Roman (cmbx10)
TBI    CM Bold Extended Text Italic (cmbxti10)
HR     CM Sans Serif (cmss10)
HI     CM Slanted Sans Serif (cmssi10)
HB     CM Sans Serif Bold Extended (cmssbx10)
HBI    CM Slanted Sans Serif Bold Extended (cmssbxo10)

There are also the following fonts which are not members of a family:

CW     CM Typewriter Text (cmtt10)
CWI    CM Italic Typewriter Text (cmitt10)

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

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.

ENVIRONMENT
GROFF_FONT_PATH
A list of directories in which to search for the devname direc-
tory in addition to the default ones.  See troff(1) and
groff_font(5) for more details.

FILES
/usr/share/groff/1.22.3/font/devdvi/DESC
Device description file.

/usr/share/groff/1.22.3/font/devdvi/F
Font description file for font F.

/usr/share/groff/1.22.3/tmac/dvi.tmac
Macros for use with grodvi.

/usr/share/groff/1.22.3/tmac/ec.tmac
Macros to switch to EC fonts.

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.
