PROGRAM:

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 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 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 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 resolution of an
Imagen printer).

The gf_file_name 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 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 banner 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.
