gftype(1) General Commands Manual gftype(1)
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.
