.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
utility loads a font bitmap to a wscons device if the device driver
|
||||
supports this.
|
||||
The font gets assigned a name in this process which it can be referred to
|
||||
by later for use on a display screen.
|
||||
The font is loaded from the specified
|
||||
.Ar fontfile ,
|
||||
or from
|
||||
.Pa stdin
|
||||
if
|
||||
.Ar fontfile
|
||||
is not provided.
|
||||
.Pp
|
||||
The options are:
|
||||
.Bl -tag -width xxxxxxxxxxx
|
||||
.It Fl f Ar ctldev
|
||||
Specify the control device of the wscons display to operate on.
|
||||
Default is
|
||||
.Pa /dev/ttyEcfg .
|
||||
.It Fl w Ar width
|
||||
Sets the width of a font character in pixels. Default is 8.
|
||||
.It Fl h Ar height
|
||||
Sets the width of a font character in pixels. Default is 16.
|
||||
.It Fl e Ar encoding
|
||||
Sets the encoding of the font. This can be either a symbolic abbreviation
|
||||
or a numeric value. Currently recognized abbreviations are
|
||||
.Dq iso
|
||||
for ISO-8859-1 encoding,
|
||||
.Dq ibm
|
||||
for IBM encoded fonts and
|
||||
.Dq pcvt
|
||||
for the custom encoding of the supplemental fonts which came with
|
||||
the BSD
|
||||
.Dq pcvt
|
||||
console driver. Per default,
|
||||
.Dq iso
|
||||
is assumed.
|
||||
.It Fl N Ar name
|
||||
Specifies a name which can be used later to refer to the font.
|
||||
In none is given, the
|
||||
.Ar fontfile
|
||||
name is used to create one.
|
||||
