GFTODVI(1)GFTODVI(1)NAMEgftodvi - make proof sheets from generic font files
SYNOPSISgftodvi [ -overflow-label-offset=real ] [ -verbose ] [
gf_file_name ]
DESCRIPTION
This manual page is not meant to be exhaustive. The com-
plete documentation 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 out-
put 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 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 Metafont 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/slantimagen6 as the `slant' font (this name
indicates a font for lines with slope 1/6 at the resolu-
tion of an Imagen printer).
The gf_file_name on the command line must be complete.
(The program prompts you for it if you don't give it.)
Because the resolution 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
defaults to 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 dis-
tance 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 banner and progress report are printed on std-
out.
ENVIRONMENTgftodvi looks for gf_file_name using the environment vari-
able 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.
