Description
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
uni-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
[lq] I[rq],
the font is assumed to be oblique
(or italic).
Options
--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
uni-width;
see
- -asc-height~n
-
height of characters with ascenders,
such as [lq]b[rq],
[lq]d[rq],
or [lq]l[rq]
- -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 [lq]A[rq]
- -comma-depth~n
-
depth of a comma
- -desc-depth~n
-
depth of characters with descenders,
such as [lq]p[rq],
[lq]q[rq],
or [lq]y[rq]
- -fig-height
-
height of figures (numerals)
- -x-height~n
-
height of lowercase letters without ascenders such as [lq]x[rq]
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.
