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 --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.
