     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
     gtroff -Tdvi;   it   will   also   input   the   macros   in

     The dvi file generated by grodvi can be printed by any  cor-
     rectly-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 pro-
     duce any output.

     There is an additional drawing command available:

     [rs]D'R dh dv'
          Draw a rule (solid black rectangle), with one corner at
          the  current position, and the diagonally opposite cor-
          ner 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 spe-
          cials unlike the other \D commands.

     The groff command [rs]X'anything'  is  translated  into  the
     same  command  in  the  dvi  file  as  would  be produced by
     [rs]special{anything} in TeX; anything  may  not  contain  a

     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.

User Commands                                           GRODVI(1)

     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  char-
     acters  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 dimen-
     sions  of  the  output  medium.   Instead,  grodvi emits the
     equivalent to TeX's  [rs]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.

          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 paper-
          size, 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 Soci-
     ety  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)  pro-
     vides  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.

          Device description file.

          Font description file for font F.

          Macros for use with grodvi.

          Macros to switch to EC fonts.

     Dvi  files  produced  by  grodvi  use a different resolution
     (57816 units per inch) to those  produced  by  TeX.   Incor-
     rectly  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.
