ADDFTINFO(1)                                                      ADDFTINFO(1)



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

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

DESCRIPTION
       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
       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.
