.TH FONTSRV 4
.SH NAME
fontsrv \- file system access to scalable fonts
.SH SYNOPSIS
.B fontsrv
[
.B -m
.I mtpt
]
[
.B -s
.I srvname
]
.SH DESCRIPTION
.I Fontsrv
presents scalable fonts
in the standard Plan 9 format
(see
.IR font (7)).
It serves a virtual directory tree mounted at
.I mtpt
(default
.IR /mnt/font )
and posted at
.I srvname
(default
.IR font ).
.PP
The fonts are arranged in a two-level tree.
The root contains directories named for each system font.
Each font directory contains subdirectories named for
a point size and whether the subfonts are anti-aliased:
.B 10
(bitmap)
.BR 10a
(anti-aliased greyscale)
.BR 12 ,
.BR 12a ,
and so on.
The font directory will synthesize additional sizes on
demand: looking up
.B 19a
will synthesize the 19-point anti-aliased size
if possible.
Each size directory contains a
.B font
file and subfont files
named
.BR x000000.bit ,
.BR x000100.bit ,
and so on
representing 256-character Unicode ranges.

.SH BUGS
.PP
Sometimes the hinting technique results in better appearance, sometimes in worse;
the heuristics whether to enable hinting is not perfect.

Subpixel rendering is not available.
