NAME
grodvi - convert groff output to TeX dvi format
SYNOPSIS

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 specials.
If the driver does not support these, the
[rs]D
commands will not produce any output.
There is an additional drawing command available:
[rs]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
[rs]D
commands.
The groff command
[rs]X'anything'
is translated into the same command in the dvi file as would be
produced by
[rs]special{anything}
in TeX;
anything
may not contain a newline.
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:
u+2n
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
[rs]m
and
[rs]M
is black.
Currently, the drawing color for
[rs]D
commands is always black, and fill color values are translated to gray.
In
troff
the
[rs]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 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.
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.

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.
