NAME    [Toc]    [Back]

       addftinfo  -  add  information to troff font files for use
       with groff

SYNOPSIS    [Toc]    [Back]

       addftinfo [ -param value...  ] res unitwidth font

DESCRIPTION    [Toc]    [Back]

       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    [Toc]    [Back]

       Each of the options changes one of the parameters that  is
       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 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.
