NAME

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

SYNOPSIS

       addftinfo [-asc-height n] [-body-depth n] [-body-height n] [-cap-height n]
                 [-comma-depth n] [-desc-depth n] [-fig-height n] [-x-height n] res unitwidth
                 font

       addftinfo --help

       addftinfo -v
       addftinfo --version

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 change one of the parameters that are 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-option 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.
