gftodvi - make proof sheets from generic font files
This manual page is not meant to be exhaustive. The complete documentation for
this version of TeX can be found in the info file or manual Web2C: A TeX
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
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
, 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,
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
as the `slant' font (this name indicates a
font for lines with slope 1/6 at the resolution of an Imagen printer).
on the command line must be complete. 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 uses the same root as the gf
file, with the .dvi
added. For example, the input file cmr10.2602gf
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

banner and progress report are printed on stdout
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.
