.SH Description
.\" ====================================================================
.
.I addftinfo
reads an
.RI AT&T \~troff
font description file
.IR font ,
adds additional font metric information required by
.\" We need the "GNU" below because the \% prefix might be empty.
.RI 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
.I 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
.I resolution
and
.I unit-width
arguments should be the same as the corresponding parameters in the
.I DESC
file.
.
.I font
is the name of the file describing the font;
if
.I font
ends with
.RB \[lq] I \[rq],
the font is assumed to be oblique
(or italic).
.
.
.\" ====================================================================
.SH Options
.\" ====================================================================
.
.B \-\-help
displays a usage message,
while
.B \-v
and
.B \-\-version
show version information;
all exit afterward.
.
.
.P
All other options change parameters that are used to derive the heights
and depths.
.
Like the existing quantities in the font description file,
each
.RI value\~ n
is in
.I "scaled points,"
.RI inches/ resolution
for a font whose type size is
.IR unit-width ;
see
.MR groff_font 5 .
.
.
.TP
.BI \-asc\-height \~n
height of characters with ascenders,
such as \[lq]b\[rq],
\[lq]d\[rq],
or \[lq]l\[rq]
.
.
.TP
.BI \-body\-depth \~n
depth of characters such as parentheses
.
.
.TP
.BI \-body\-height \~n
height of characters such as parentheses
.
.
.TP
.BI \-cap\-height \~n
height of uppercase letters such as \[lq]A\[rq]
.
.
.TP
.BI \-comma\-depth \~n
depth of a comma
.
.
.TP
.BI \-desc\-depth \~n
depth of characters with descenders,
such as \[lq]p\[rq],
\[lq]q\[rq],
or \[lq]y\[rq]
.
.
.TP
.B \-fig\-height
height of figures (numerals)
.
.
.TP
.BI \-x\-height \~n
height of lowercase letters without ascenders such as \[lq]x\[rq]
.
.
.P
.I 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.
