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
example, mf(1), to a device independent (DVI) file (that can then be
typeset 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 typeset diagonal lines, which otherwise have to be simulated
using horizontal and vertical rules. The default gray, title, and la-
bel 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
Metafont source file, or you can change the fonts online. An online di-
alog 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/slan-
timagen6 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 res-
olution is part of the extension, it would not make sense to append a
default 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 ex-
tension 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 equa-
tions (if any) are typeset. The value is given in TeX points. The de-
fault 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.
