NAME    [Toc]    [Back]

       grodvi - convert groff output to TeX dvi format

SYNOPSIS    [Toc]    [Back]

       grodvi [ -dv ] [ -wn ] [ -Fdir ] [ files...  ]

DESCRIPTION    [Toc]    [Back]

       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
       /usr/share/tmac/tmac.dvi; if the input  is  being  preprocessed
     with     eqn     it     will     also     input

       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        not  produce any output.

       There is an additional drawing command available:

      '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

       The groff command'anything' is translated into the same
       command in the dvi file as  would  be  produced  by pe-
       cial{anything} in TeX; anything may not contain a newline.

       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.

       In  troff  the   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

OPTIONS    [Toc]    [Back]

       -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.

       -v     Print the version number.

       -wn    Set  the default line thickness to n thousandths of
              an em.

       -Fdir  Search directory dir/devdvi  for  font  and  device
              description files.

FILES    [Toc]    [Back]

              Device description file.

       /usr/share/groff_font/devdvi/ F
              Font description file for font F.

              Macros for use with grodvi.

BUGS    [Toc]    [Back]

       Dvi  files  produced  by grodvi use a different resolution
       (57816 units per inch) to 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.
