Housenumbers don't get rendered when they are located very close.


In osmarender the three houses in the middle are "6", "6a" and "6b"

In mapnik only "6" and "6b" are shown.

This is the standard mapnik collision handling, I don't think very much can be done about it.

Maybe it is possible to place each housenumber in the middle of the polygon (building). Sometimes housenumbers seem to get placed at the edge of the polygon, in the example "6b" it is right in the middle between the two buildings "6a" and "6b". Also buildings that are not so close together have the housenumber on the edge or beyond (see housenumber 13 in the example).

There was a bug in Mapnik which caused slight errors in the placement of the text in small polygons. I've fixed this in mapnik svn 880 and the points should start appearing at the centroid of the polygon from now on. It may take about a week before all the tiles are rendered with this fix.

Where these labels are too close together you may still see some not being rendered.

Thank you very much - the cases which i objected render perfect now.
