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.   In‐
       stead,  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 speci‐
              fied, 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, per‐
       haps 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  de‐
       sign 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-spe‐
       cific 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  pro‐
       trude  by  one  pixel.   This  is  a consequence of the way TeX requires that the heights and
       widths of rules be rounded.
