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.
