grodvi - groff output driver for TeX DVI format
grodvi [-dl] [-F dir] [-p paper-format] [-w n] [file ...]
grodvi --help
grodvi -v
grodvi --version
The GNU roff DVI output driver translates the output of into TeX
DVI format. Normally, grodvi is invoked by when the latter is
given the “-T dvi” option. (In this installation, ps is the
default output device.) Use groff's -P option to pass any
options shown above to grodvi. If no file arguments are given,
or if file is “-”, grodvi reads the standard input stream.
Output is written to the standard output stream.
The DVI file generated by grodvi can interpreted by any correctly
written DVI driver. troff drawing primitives are implemented
using tpic version 2 specials. If the driver does not support
these, \D escape sequences will not produce any output.
Encapsulated PostScript (EPS) files can be easily included; use
the PSPIC macro. pspic.tmac is loaded automatically by dvi.tmac.
See
The default color used by the \m and \M escape sequences is
black. Currently, the stroke color for \D drawing escape
sequences is black; fill color values are translated to gray.
In groff, as in AT&T troff, the \N escape sequence can be used to
access any glyph in the current font by its position in the
corresponding TFM file.
By design, the DVI format doesn't care about the physical
dimensions of the output medium. Instead, grodvi emits the
equivalent to TeX's \special{papersize=width,length} on the first
page; dvips (or another DVI driver) then sets the page size
accordingly. If either the page width or length is not positive,
no papersize special is output.
A device control escape sequence \X'anything' is translated to
the same DVI file instructions as would be produced by
\special{anything} in TeX; anything cannot contain a newline.
Typefaces
grodvi supports the standard four styles: R (roman), I (italic),
B (bold), and BI (bold-italic). Fonts are grouped into families
T and H having members in each style. “CM” abbreviates “Computer
Modern”.
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)
The following fonts are not members of a family.
CW CM Typewriter Text (cmtt10)
CWI CM Italic Typewriter Text (cmitt10)
Special fonts include MI (cmmi10), S (cmsy10), EX (cmex10), SC
(cmtex10, only for CW), and, perhaps surprisingly, TR, TI, and
CW, because TeX places some glyphs in text fonts that troff
generally does not. 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). They
are are not mounted by default.
The troff option -mec loads the ec.tmac macro file, employing the
EC and TC fonts instead of CM. These are designed similarly to
the Computer Modern fonts; further, they provide Euro \[Eu] and
per mille \[%0] glyphs. ec.tmac must be loaded before any
language-specific macro files because it does not set up the
codes necessary for automatic hyphenation.
Font description files
Use to create groff font description files from TFM (TeX font
metrics) files. The font description file should contain the
following additional directives, which tfmtodit generates
automatically.
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 design size in the TFM file is n.
Drawing commands
grodvi supports an additional drawing command.
\D'R dh dv'
Draw a rule (solid black rectangle) with one corner at the
drawing position, and the diagonally opposite corner at
the drawing position +(dh,dv), which becomes the new
drawing position afterward. This command produces a rule
in the DVI file and so can be printed even with a driver
that does not support tpic specials, unlike the other \D
commands.
--help displays a usage message, while -v and --version show
version information; all exit afterward.
-d Do not use tpic specials to implement drawing commands.
Horizontal and vertical lines are implemented by rules.
Other drawing commands are ignored.
-F dir Prepend directory dir/devname to the search path for font
and device description files; name is the name of the
device, usually dvi.
-l Use landscape orientation rather than portrait.
-p paper-format
Set physical dimensions of output medium, overriding the
papersize, paperlength, and paperwidth directives in the
DESC file. paper-format can be any argument accepted by
the papersize directive; see
-w n Draw rules (lines) with a thickness of n thousandths of an
em. The default thickness is 40 (0.04 em).
GROFF_FONT_PATH
lists directories in which to search for devdvi, grodvi's
directory of device and font description files. See and
/usr/local/share/groff/1.23.0/font/devdvi/DESC
describes the dvi output device.
/usr/local/share/groff/1.23.0/font/devdvi/F
describes the font known as F on device dvi.
/usr/local/share/groff/1.23.0/tmac/dvi.tmac
defines font mappings, special characters, and colors for
use with the dvi output device. It is automatically
loaded by troffrc when the dvi output device is selected.
/usr/local/share/groff/1.23.0/tmac/ec.tmac
configures the dvi output device to use the EC and TC font
families instead of CM (Computer Modern).
DVI files produced by grodvi use a different resolution (57,816
units per inch) from 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.
