Description         top

       grodvi is a driver for groff that produces TeX DVI format.
       Normally it should be run via “groff -Tdvi”.  This will run “‐
       troff -Tdvi”, read the macros in /usr/local/share/groff/1.23.0/
       tmac/dvi.tmac, and pipe the output to grodvi.

       The DVI file generated by grodvi can be printed by any correctly-
       written DVI driver.  troff drawing primitives are implemented
       using 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.  See groff_tmac(5) for
       a detailed description.

       Font files for grodvi can be created from TFM (TeX font metrics)
       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

       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 groff, as in AT&T 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         top

       --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 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.

              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).

       -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         top

       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

              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.  ec.tmac must be called before any
       language-specific files; it doesn't take care of .hcode values.

Environment         top

Bugs         top

       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

       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.
