       addftinfo - add font metrics to troff fonts 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] resolution unit-width font

       addftinfo --help

       addftinfo -v
       addftinfo --version

Description

       addftinfo reads an AT&T troff font  description  file  font,  adds  additional  font  metric  information
       required  by  GNU troff(1), and writes the combined result to the standard output.  The information added
       is derived from the font's  existing  parameters  and  assumptions  about  traditional  troff  names  for
       characters.   Among the font metrics added are the heights and depths of characters (how far each extends
       vertically above and below the baseline).  The resolution and unit-width 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 is assumed to be oblique (or italic).

Options

       --help displays a usage message, while -v and --version show version information; all exit afterward.

       All other options change parameters that are used to derive the heights and depths.   Like  the  existing
       quantities  in  the font description file, each value n is in scaled points, inches/resolution for a font
       whose type size is unit-width; see groff_font(5).

       -asc-height n
              height of characters with ascenders, such as “b”, “d”, or “l”

       -body-depth n
              depth of characters such as parentheses

       -body-height n
              height of characters such as parentheses

       -cap-height n
              height of uppercase letters such as “A”

       -comma-depth n
              depth of a comma

       -desc-depth n
              depth of characters with descenders, such as “p”, “q”, or “y”

       -fig-height
              height of figures (numerals)

       -x-height n
              height of lowercase letters without ascenders such as “x”

       addftinfo makes no attempt to use the  specified  parameters  to  infer  unspecified  parameters.   If  a
       parameter  is  not  specified,  the  default will be used.  The defaults are chosen to produce reasonable
       values for a Times font.
