Ubuntu Manpage: grodvi - convert groff output to TeX dvi format

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/1.22.2/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/1.22.2/font/devdvi/DESC
              Device description file.

       /usr/share/groff/1.22.2/font/devdvi/F
              Font description file for font F.

       /usr/share/groff/1.22.2/tmac/dvi.tmac
              Macros for use with grodvi.

       /usr/share/groff/1.22.2/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.
