NAME¶

gftype - verify and translate a generic font (gf) bitmap file to plain text

SYNOPSIS¶

gftype [-i] [-m] gf_file[gf] [output_file]

DESCRIPTION¶

The gftype program translates a gf (generic font) bitmap file output by, typically, mf(1), to a file that humans can read. It also serves as a gf file-validating program (i.e., if gftype can read it, it's correct) and as an example of a gf-reading program for other software that wants to read gf files.

The gf_file on the command line must include the resolution, but can omit the suffix "gf". If no output_file is specified, the output goes to stdout.

OPTIONS¶

See tex(1) for details of command-line parsing.

-images

Includes ASCII art images of the characters in the output.

-mnemonics

Include a symbolic listing of the gf commands in the output.

The standard -help and -version options are also supported.

ENVIRONMENT¶

The program looks for gf_file using the environment variables GFFONTS, GLYPHFONTS, and TEXFONTS, in that order. If none are set, it uses the system default. See the Kpathsea manual at https://tug.org/kpathsea for the details of the searching.
