       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 -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.
