[GFTYPE(1)](https://www.chedong.com/phpMan.php/man/GFTYPE/1/markdown)                              General Commands Manual                             [GFTYPE(1)](https://www.chedong.com/phpMan.php/man/GFTYPE/1/markdown)



## NAME
       gftype - translate a generic font file for humans to read

## SYNOPSIS
       **gftype** [**-i**] [**-m**] _gf_file_name_ [_output_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 **gftype** program translates a _gf_ (generic font) file output by, for example,  [**mf**(1)](https://www.chedong.com/phpMan.php/man/mf/1/markdown),  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_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. If no _output_file_name_ is specified, the output goes to _stdout_.

## OPTIONS
       The output file includes bitmap images of the characters, if **-i** is given on the command line,
       and a symbolic listing of the _gf_ commands, if **-m** is specified.

## ENVIRONMENT
       **gftype** 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.

## AUTHORS
       David  Fuchs  and  Don 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.
