I think I found the reason: I am using "point" placement instead of line-placement. Is it possible to use point-placement on road-shields? The reason for me to use it was that I needed character-spacing which is only working in point-placement, and I also want to use the dx/dy offsets which seem to be working as well only in point-placement (to offset the text, I don't use the shield-offsets, but I use asymmetric shield icons). Are these to be considered bugs (so I would file a ticket) or is it my fault to use point-placement where I can't do it? The strange thing is that it generally works, but sometimes it creates these strange offsets (outside the shield, sometimes repeated up to 4 times the same shields text hundreds of pixels away, the offset is always only horizontal, never vertical). cheers, Martin _______________________________________________ Mapnik-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/mapnik-users
