addftinfo reads an AT&T troff font
description file font, adds additional font metric information
required by GNU troff(1), and writes the combined result to
the standard output. The information added is derived from the font's
existing parameters and assumptions about traditional troff names for
characters. Among the font metrics added are the heights and depths of
characters (how far each extends vertically above and below the baseline).
The resolution and unit-width 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 is assumed to be oblique (or italic).
--help displays a usage message, while -v and
--version show version information; all exit afterward.
All other options change parameters that are used to derive the
heights and depths. Like the existing quantities in the font description
file, each value n is in scaled points,
inches/resolution for a font whose type size is unit-width;
see groff_font(5).
- -asc-height n
- height of characters with ascenders, such as “b”,
“d”, or “l”
- -body-depth n
- depth of characters such as parentheses
- -body-height n
- height of characters such as parentheses
- -cap-height n
- height of uppercase letters such as “A”
- -comma-depth n
- depth of a comma
- -desc-depth n
- depth of characters with descenders, such as “p”,
“q”, or “y”
- -fig-height
- height of figures (numerals)
- -x-height n
- height of lowercase letters without ascenders such as
“x”
addftinfo makes no attempt to use the specified parameters
to infer unspecified parameters. If a parameter is not specified, the
default will be used. The defaults are chosen to produce reasonable values
for a Times font.
