GFTODVI(1) General Commands Manual GFTODVI(1)
NAME
gftodvi - make proof sheets from generic font files
SYNOPSIS
gftodvi [-overflow-label-offset=real] [-verbose] gf_file_name
DESCRIPTION
This manual page is not meant to be exhaustive. The complete documenta-
tion for this version of TeX can be found in the info file or manual
Web2C: A TeX implementation.
The gftodvi program converts a generic font (gf) file output by, for ex-
ample, mf(1), to a device independent (DVI) file (that can then be type-
set using the same software that has already been written for TeX). The
characters in the gf file will appear one per page, with labels, titles,
and annotations as specified in Appendix H (Hardcopy Proofs) of The
Metafontbook.
gftodvi uses other fonts in addition to the main gf file. A `gray' font
is used to typeset the pixels that actually make up the character. (We
wouldn't want all the pixels to be simply black, since then labels, key
points, and other information would be lost.) A `title' font is used
for the information at the top of the page. A `label' font is used for
the labels on key points of the figure. A `slant' font is used to type-
set diagonal lines, which otherwise have to be simulated using horizon-
tal and vertical rules. The default gray, title, and label fonts are
gray, cmr8, and cmtt10, respectively; there is no default slant font.
To change the default fonts, you can give special commands in your Meta-
font source file, or you can change the fonts online. An online dialog
ensues if you end the gf_file_name with a `/'. For example,
gftodvi cmr10.300gf/
Special font substitution: grayfont black
OK; any more? grayfontarea /home/art/don/
OK; any more? slantfont /home/fonts/slantimagen6
OK; any more? <RET>
will use /home/art/don/black as the `gray' font and /home/fonts/slantim-
agen6 as the `slant' font (this name indicates a font for lines with
slope 1/6 at the resolution of an Imagen printer).
The gf_file_name on the command line must be complete. Because the reso-
lution is part of the extension, it would not make sense to append a de-
fault extension as is done with TeX or DVI-reading software. The output
file name uses the same root as the gf file, with the .dvi extension
added. For example, the input file cmr10.2602gf would become cmr10.dvi.
OPTIONS
The argument to -overflow-label-offset specifies the distance from the
right edge of the character bounding box at which the overflow equations
(if any) are typeset. The value is given in TeX points. The default is
a little over two inches.
Without the -verbose option, gftodvi operates silently. With it, a ban-
ner and progress report are printed on stdout.
ENVIRONMENT
gftodvi looks for gf_file_name using the environment variable GFFONTS.
If that is not set, it uses the variable TEXFONTS. If that is not set,
it uses the system default.
See tex(1) for the details of the searching.
