NAME
addftinfo - add information to troff font files for
use with groff
SYNOPSIS
addftinfo [ -v ] [
-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
-v prints the version number.
All other 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.
