[Fontconfig] all font names of one font should be putted into <match target="font"> clause of config file?
When run fc-match command, I find a issue. My system is Ubuntu 7.04,
which has a ttf-arphic-uming package, it contains a ttf font --
/usr/sahre/fonts/truetype/arphic/uming.ttf, and a config file --
/etc/fonts/conf.d/ttf-arphic-uming.
in locale en_US.utf8, run these commands:
1)
$ fc-list ''AR PL ShanHeiSun Uni'' file family familylang
/usr/share/fonts/truetype/arphic/uming.ttf: AR PL ShanHeiSun
Uni,????PL????????Uni,????PL????????Uni:familylang=en,zh-tw,zh-cn
2)
$ fc-match -v ''AR PL ShanHeiSun Uni'' # font name of familylang
en
Pattern has 33 elts (size 48)
family: "AR PL ShanHeiSun Uni"(s)
familylang: "zh-tw"(s)
......
size: 12(f)(s)
pixelsize: 12.5(f)(s)
foundry: "unknown"(s)
antialias: FcFalse(w)
......
3)
$ fc-match -v ''????PL????????Uni'' # font name of familylang
zh-tw
Pattern has 30 elts (size 32)
family: "????PL????????Uni"(s)
familylang: "zh-tw"(s)
.......
size: 12(f)(s)
pixelsize: 12.5(f)(s)
foundry: "unknown"(s)
antialias: FcTrue(w)
.......
4)
$ fc-match -v ''????PL????????Uni'' # font name of familylang
zh-cn
Pattern has 30 elts (size 32)
family: "????PL????????Uni"(s)
familylang: "zh-tw"(s)
......
size: 12(f)(s)
pixelsize: 12.5(f)(s)
foundry: "unknown"(s)
antialias: FcTrue(w)
......
config file /etc/fonts/conf.d/ttf-arphic-uming has content just like:
<fontconfig>
<match target="font">
<test name="family">
<string>AR PL ShanHeiSun Uni</string>
<string>AR PL ShanHeiSun Uni MBE</string>
</test>
.......
<edit
name="antialias"><bool>false</bool></edit>
.......
</match>
<match target="font">
<test name="family">
<string>AR PL ShanHeiSun Uni</string>
<string>AR PL ShanHeiSun Uni MBE</string>
</test>
<test name="pixelsize"
compare="more_eq"><int>17</int></test>
<edit name="antialias"
mode="assign"><bool>true</bool></edit>
.....
</match>
</fontconfig>
we can see that command 2) accept above rule, but 3) and 4) dosn''t.
My question is: all font names of one font should be putted into
<match target="font"> clause? as a fontconfig user, if a clause
in
config file which disable antialias for font uming.ttf, it should work
for any font name of uming.ttf.
Another issue: familylang outputs of command 2), 3), 4) are all same.
instead, 2) should be "en", and 4) should be "zh-cn".
