Sh DESCRIPTION
The
Nm
utility loads a font bitmap into the wsfont font pool
(or 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 standard input if
Ar fontfile
is not provided.
Pp
The options are:
Bl -tag -width Fl
It Fl B
Specifies that the font data is ordered right-to-left byte wise.
The default is left-to-right.
It Fl b
Specifies that the font data is ordered right-to-left bit wise.
The default is left-to-right.
It Fl e Ar encoding
Sets the encoding of the font.
This can be either a symbolic name or a numeric value.
Currently recognized names are:
Bl -tag -width Ql
It Ql iso
ISO-8859-1 encoding
It Ql ibm
IBM CP437 encoding
It Ql pcvt
the custom encoding of the supplemental fonts which came with the
Bx
Dq pcvt
console driver
It Ql iso2
ISO-8859-2 (Eastern European) encoding
It Ql iso7
ISO-8859-7 (Greek) encoding
It Ql koi8r
KOI8-R (Russian) encoding
El
Pp
Per default,
Ql iso
is assumed.
It Fl f Ar wsdev
Specify the device to operate on.
Default is
Pa /dev/wsfont .
It Fl h Ar height
Sets the height of a font character in pixels.
Default is 16.
It Fl l
Print a list of fonts that have been loaded or are built-in to the kernel.
It Fl N Ar name
Specifies a name which can be used later to refer to the font.
If none is given, the
Ar fontfile
name is used to create one.
It Fl v
Prints the font's properties before loading it.
It Fl w Ar width
Sets the width of a font character in pixels.
Default is 8.
El
Pp
Nm
supports
Ql \&.wsf
file format that contains the necessary information about the font in
the font file itself.
Such files can be loaded without specifying any arguments,
though
Fl N
can be used to override the font name.
Pp
Typically, the
Nm
utility will be executed during system startup by the
Xr rc 8
script.
See
Xr wscons.conf 5 .

Sh EXAMPLES
Load ISO-encoded 20-pixel high Terminus font
and use it on the current console
Pp
Bd -literal -offset indent
# wsfontload /usr/share/wscons/fonts/ter-120n.wsf
# wsfontload -l | grep Terminus
Terminus20-ISO8859-1 10x20
# wsconsctl -f `tty` -dw font=Terminus20-ISO8859-1
Ed
Pp
Load the ISO-encoded 16\[tmu]32 Spleen font
and switch the first console screen to use it:
Pp
Bd -literal -offset indent
# wsfontload -w 16 -h 32 -e iso -N spleen32 \e
       /usr/share/wscons/fonts/spleen-16x32.fnt
# wsconsctl -dw font=spleen32
Ed
Pp
Load the IBM-encoded 8\[tmu]8-font from the
Xr wscons 4
distribution:
Pp
Bd -literal -offset indent
# wsfontload -N myname -h 8 -e ibm \e
   /usr/share/wscons/fonts/vt220l.808
Ed
Pp
This or another 8\[tmu]8-font is necessary to use the
50-line screen type on
Xr vga 4
displays.
