NAME

       grodvi - convert groff output to TeX dvi format

SYNOPSIS

       grodvi [ -dlv ] [ -Fdir ] [ -ppapersize ] [ -wn ] [ files... ]

       It is possible to have whitespace between a command line option and its
       parameter.

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/1.21/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

       -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/1.21/font/devdvi/DESC
              Device description file.

       /usr/share/groff/1.21/font/devdvi/F
              Font description file for font F.

       /usr/share/groff/1.21/tmac/dvi.tmac
              Macros for use with grodvi.

       /usr/share/groff/1.21/tmac/ec.tmac
              Macros to switch to EC fonts.

BUGS

       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.
