No, there is no compositing of the caption layer yet. I had simply forgotten about this.

As > far as I can tell this isn't happening at the moment. Right now we take the z12 captionless and recursively stitch them down to z6, saving them in the 'tiles' layer. I will make it like it used to work. I am sorry to say that I had no real idea of how the lowzoom and caption thing was working. > BTW Is there any mechanism for generating caption tiles at z11 and lower, or > has that been overlooked? It's possible on the server side now. There was no mechanism in the mainstream tah client so far, so there is nothing that I supported. To make things dead easy tile sets are z0-5,z6-11,z12-17. It would be possible but not trivial to convince me of the need for finer grained tile sets, BTW. Right now, you can issue a request for the "caption" layer at min_z=6, this would cause the server to hand that request out to a tah client. The problem is that regular tah clients are not configured to actually be able to create the caption layer and that they wouldn't create a tileset from z6 - z11 spaetz _______________________________________________ Tilesathome mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/tilesathome
