NAME

grodvi - convert groff output to TeX dvi format . .

SYNOPSIS

grodvi [ -dv ] [ I -w n ] [ I -F dir ] [ R files ... ]
It is possible to have whitespace between a command line option and its parameter. . .

DESCRIPTION

grodvi is a driver for groff that produces dvi format. . Normally it should be run by R groff -Tdvi . . This will run R troff -Tdvi ; it will also input the macros R /usr/share/groff/1.18.1/tmac/dvi.tmac ; if the input is being preprocessed with eqn it will also input R /usr/share/groff/1.18.1/font/devdvi/eqnchar . .
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 \[rs]D commands will not produce any output. .
There is an additional drawing command available: .
I \[rs]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 \[rs]D commands. .
The groff command I \[rs]X' anything ' is translated into the same command in the dvi file as would be produced by I \[rs]special{ anything } in ; anything may not contain a newline. .
For inclusion of EPS image files, grodvi loads pspic.tmac automatically, 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 commands: . I internalname  name The name of the tfm file (without the .tfm extension) is R name . .
I checksum  n
The checksum in the tfm file is R n . .
I designsize  n
The designsize in the tfm file is R n . .
These are automatically generated by tfmtodit. .
The default color for \[rs]m and \[rs]M is black. . Currently, the drawing color for \[rs]D commands is always black, and fill color values are translated to gray. .
In troff the \[rs]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. . Horizontal and vertical lines will be implemented by rules. . Other drawing commands will be ignored. .
-v
Print the version number. .
I -w n
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. .
I -F dir
Prepend directory B dir /dev name to the search path for font and device description files; name is the name of the device, usually R dvi . . .

USAGE

There are styles called R R , R I , R 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, R TR , R TI , and R CW , due to the different font encodings of text fonts. . For italic fonts, CWI is used instead of R 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 R 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. . .

BUGS

Dvi files produced by grodvi use a different resolution (57816 units per inch) to those produced by . . Incorrectly written drivers which assume the resolution used by , rather than using the resolution specified in the dvi file will not work with R 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 requires that the heights and widths of rules be rounded. . .
