ADDFTINFO(1) MachTen Programmer’s Manual 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 char-
acters. 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.
