.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.
|
|

|
