GRODVI(1) General Commands Manual GRODVI(1)
grodvi - convert groff output to TeX DVI format
grodvi [ -dlv ] [ -Fdir ] [ -ppapersize ] [ -wn ] [ files... ]
It is possible to have whitespace between a command-line option and
its parameter.
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/local/share/groff/1.22.3/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.
-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.
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 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.
GROFF_FONT_PATH
A list of directories in which to search for the devname
directory in addition to the default ones. See troff(1) and
groff_font(5) for more details.
/usr/local/share/groff/1.22.3/font/devdvi/DESC
Device description file.
/usr/local/share/groff/1.22.3/font/devdvi/F
Font description file for font F.
/usr/local/share/groff/1.22.3/tmac/dvi.tmac
Macros for use with grodvi.
/usr/local/share/groff/1.22.3/tmac/ec.tmac
Macros to switch to EC fonts.
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.
