NAME
    grodvi - convert groff output to TeX dvi format

SYNOPSIS
    grodvi [ -dv ] [ -wn ] [ -Fdir ] [ 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 /usr/share/groff/1.18.1/tmac/dvi.tmac; if the input is
    being  preprocessed  with   eqn   it  will  also  input
    /usr/share/groff/1.18.1/font/devdvi/eqnchar.

    The dvi file generated by grodvi can be printed by any correctly-writ-
    ten 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 cur-
    rent 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; any-
    thing may not contain a newline.

    For inclusion of EPS image files, grodvi loads  pspic.tmac automati-
    cally, providing the PSPIC macro.  Please check grops (1) for a
    detailed description of this macro.

    Font files for grodvi can be created from tfm files using tfmtodit(1).
    The font description file should contain the following additional com-
    mands:

    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.

OPTIONS
    -d   Do not use tpic specials to implement drawing commands.  Hori-
    zontal 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. If
    this option isn't specified, the  line thickness defaults to
    0.04 em.

    -Fdir Prepend directory dir/devname to the search path for font and
    device description files; name is the name of the  device, usu-
    ally dvi.

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), 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 (loading the file ec.tmac) EC and TC fonts are
    used. 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.

    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.
