addftinfo - add information to troff font files for use with groff

 

NAME

        addftinfo - add information to troff font files for use with groff
 

SYNOPSIS

        addftinfo [ -v ] [ -param value...  ] res unitwidth font
 

DESCRIPTION

        addftinfo  reads a troff font file and adds some additional font-metric
        information that is used by the groff system.  The font file  with  the
        information  added  is written on the standard output.  The information
        added is guessed using some parametric information about the  font  and
        assumptions about the traditional troff names for characters.  The main
        information added is the heights and depths of characters.  The res and
        unitwidth  arguments should be the same as the corresponding parameters
        in the DESC file; font is the name of the file describing the font;  if
        font ends with I the font will be assumed to be italic.
 

OPTIONS

        -v prints the version number.
 
        All  other options changes one of the parameters that is used to derive
        the heights and depths.  Like the existing quantities in the font file,
        each  value  is in inches/res for a font whose point size is unitwidth.
        param must be one of:
 
        x-height
               The height of lowercase letters without ascenders such as x.
 
        fig-height
               The height of figures (digits).
 
        asc-height
               The height of characters with ascenders, such as b, d or l.
 
        body-height
               The height of characters such as parentheses.
 
        cap-height
               The height of uppercase letters such as A.
 
        comma-depth
               The depth of a comma.
 
        desc-depth
               The depth of characters with descenders, such as p,q, or y.
 
        body-depth
               The depth of characters such as parentheses.
 
        addftinfo makes no attempt to use the specified parameters to guess the
        unspecified  parameters.   If  a parameter is not specified the default
        will be used.  The defaults are chosen to have  the  reasonable  values
        for a Times font.

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
