Re: [OSM-talk] Language rendering query
Mapnik has updated north india tiles.
It sure has hindi font but rendered it all wrongly.
http://www.openstreetmap.org/?lat=27.61&lon=78.72&zoom=8&layers=B000FTF
If its the DejaVu font, i think it worked flawlessly on my self-generated
TAH tiles.
Any suggestions?

Re: [OSM-talk] Language rendering query
We could give other devnagri/other language alternatives even on that css
definition.
To temporarily test/solve my language rendering problem, I have recently ran
tilesGen xy with the tiles im interested in.
So now, New Delhi and a lot of the Nation Capital Region has a nice (Hindi)
names.
Now I wonder, would mapnik be hindi-ready this Wednesday.

What I don't understand is even if you install alternative fonts, the
osmarender stylesheets have entries such as this from caption-z11.xml:
/* Places - generic styles */
.caption-casing {
fill: white;
stroke: white;
font-family: "DejaVu Sans";
font-weight: normal;
text-anchor: middle;
stroke-miterlimit: 1.5;
}
.caption-core {
stroke: white;
stroke-width: 0px;
font-family: "DejaVu Sans";
font-weight: normal;
text-anchor: middle;
stroke-miterlimit: 1.5;
}
How would it know to use a font other than DejaVu Sans even if they were
installed? And in case it is relevant I'm using Windows?

(Just like shown in Sri Lanka/China/etc) Would be alt easier if you supplied links so we could check the data. 1) New Delhi seems to be show in mapnik Zoom 8. http://openstreetmap.org/?lat=28.6&lon=77.2&zoom=8&layers=B000FTF Though osmarender seems to mess things up: http://openstreetmap.org/?lat=28.6&lon=77.2&zoom=8&layers=B000FTF I don't know why but Openstreetmap rendering rules are optimized for Gemany and the UK. Might be one of the problems. 2) Multi language stuff is hard, I would go for the Armenian way see: http://openstreetmap.org/?lat=40.15&lon=45.76&zoom=7&layers=B000FTF Basically the city us tagged like this: name:en=Swamp name:sv=Träsk name=Träsk (Swamp) ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
