- NAME
- gftodvi - make proofsheets from generic font files
-
- SYNOPSIS
- gftodvi [gf_file_name]
-
- DESCRIPTION
- The gftodvi program converts a generic font (GF) file output
- by, for example, mf(1), to a device independent (DVI) file
- that can be typeset using the same software as for TeX out-
- put. The characters in the GF file will appear one per page,
- with labels, titles, and annotations as specified in Appen-
- dix 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 io.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. (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 add on 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 io.2602gf would become io.dvi.
-
- ENVIRONMENT VARIABLES
- gftodvi uses the environment variable GFFONTS to search for
- the GF file. If GFFONTS is not set, it uses the current
- directory.

-
-
-
-
- The TEXFONTS environment variable is used to find the TFM
- files that the program needs. If TEXFONTS is not set, the
- system default TeX:fonts is used. See tex(1) for the details
- of the searching.
-
- FILES
- TeX:fonts/{gray.tfm,...} the default fonts
-
- TeX:mfinputs/{gray.mf,...} the Metafont sources

- AUTHORS
- Donald Knuth wrote the program. It was published as part of
- the METAFONTware technical report, available from the TeX
- Users Group. Paul Richards originally ported it to Unix.
