## Name



           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
           further font metric information required by GNU _troff_(1), and
           writes the combined result to the standard output stream.  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.
    


## Exit status



           _addftinfo_ exits with status **0** on successful operation, and
           status **2** if the program cannot interpret its command-line
           arguments.
