Hi List, I've been struggling with getting a few final bugs worked out of my mapping project. I was having lots of problems with labels being truncated on tile boundaries. Then I added metaTile=True to my tilecache.cfg and about 95% of the labeling issues were solved, not to mention tile requests being handled about 5x faster! However, there are still a few labels being chopped off at tile boundaries.
two examples here: *"Ander" should be "Anderson"* : http://map.umt.edu/?zoom=4&lat=5194066.062&lon=272487.836&layers=BT *road labels shouldn't be placed that closely, chopped* : (other road labels on the map render correctly with correct spacing) http://map.umt.edu/?zoom=4&lat=5194344.808&lon=272348.312&layers=BTT here are the two rules from my xml mapfile rendering the labels, respectively: <Rule> <ElseFilter/> <MaxScaleDenominator>2150</MaxScaleDenominator> <MinScaleDenominator>1000</MinScaleDenominator> <TextSymbolizer name="nameCode" face_name="DejaVu Sans Book" size="10" fill="#000" halo_radius="1" placement="point" wrap_width="10" allow_overlap="true" dy="-3"/> </Rule> <Rule> <ElseFilter/> <MaxScaleDenominator>2150</MaxScaleDenominator> <MinScaleDenominator>1000</MinScaleDenominator> <TextSymbolizer name="FENAME" face_name="DejaVu Sans Book" size="11" fill="#000" halo_radius="1" placement="line" spacing="600" allow_overlap="false" avoid_edges="true" min_distance="1200"/> </Rule> Is there anything further i can do to keep this from happening, i've heard about adding a "gutter", but havent seen an example of that being implemented. Is this completely a tilecache issue or can i modify my xml to solve this issue? My setup: mapnik 0.5.1 / tilecache 2.04 / Openlayers 2.5 running on Ubuntu server 8.10 64bit Thanks! -Jamie Robertson
