NAME

       grodvi - convert groff output to TeX DVI format

SYNOPSIS

       grodvi [-dl] [-F dir] [-p papersize] [-w n] [file ...]

       grodvi --help

       grodvi -v
       grodvi --version

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/1.22.4/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.

OPTIONS

       Whitespace is permitted between a command-line option and its argument.

       -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.

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 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.

ENVIRONMENT

       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.

FILES

       /usr/share/groff/1.22.4/font/devdvi/DESC
              Device description file.

       /usr/share/groff/1.22.4/font/devdvi/F
              Font description file for font F.

       /usr/share/groff/1.22.4/tmac/dvi.tmac
              Macros for use with grodvi.

       /usr/share/groff/1.22.4/tmac/ec.tmac
              Macros to switch to EC fonts.

BUGS

       Dvi files produced by grodvi use a different resolution (57816 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.
