GRODVI(1) GRODVI(1)
NAME
grodvi - convert groff output to TeX dvi format
SYNOPSIS
grodvi [ -dv ] [ -wn ] [ -Fdir ] [ 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
/usr/share/groff/1.18.1.1/tmac/dvi.tmac; if the input is being preprocessed with
eqn it will also input /usr/share/groff/1.18.1.1/font/devdvi/eqnchar.
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 spe-
cials. If the driver does not support these, the \D commands will not produce any
output.
There is an additional drawing command available:
\Dâ€â€™R dh dvâ€â€™
Draw a rule (solid black rectangle), with one corner at the current posi-
tion, and the diagonally opposite corner at the current position +(dh,dv).
Afterwards the current position will be at the opposite corner. This pro-
duces 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 \Xâ€â€™anythingâ€â€™ is translated into the same command in the dvi file
as would be produced by \special{anything} in TeX; anything may not contain a new-
line.
For inclusion of EPS image files, grodvi loads pspic.tmac automatically, providing
the PSPIC macro. Please check grops (1) for a detailed description of this macro.
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 com-
mands 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.
OPTIONS
-d Do not use tpic specials to implement drawing commands. Horizontal and ver-
tical 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. If this option
isn’t specified, the line thickness defaults to 0.04 em.
-Fdir Prepend directory dir/devname to the search path for font and device
description files; name is the name of the device, usually dvi.
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), 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 (loading the file ec.tmac) EC and TC fonts are used. 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.
FILES

/usr/share/groff/1.18.1.1/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 some-
times protrude by one pixel. This is a consequence of the way TeX requires that
the heights and widths of rules be rounded.
