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


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


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


–v prints the version number.

All other options change one of the parameters that are 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-option must be one of:

The height of lowercase letters without ascenders such as x.

The height of figures (digits).

The height of characters with ascenders, such as b, d or l.

The height of characters such as parentheses.

The height of uppercase letters such as A.

The depth of a comma.

The depth of characters with descenders, such as p, q, or y.

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.
