Are you using the "labelcache_map_edge_buffer" setting in the WEB METADATA 
block? That creates a virtual buffer along the edges of the map and renders 
labels whose label point falls in the buffer, so you get partials that would 
otherwise not be displayed because of clipping.

Subject: [MapServer-users] Fixing labels on tiled images

Hi!

I'm trying to render a large map image for printing, but doing it in a single 
request times out and it's not optimal to have it like that as a service.

So I render smaller tiles of the large image and piece it together.

I'm having an issue with the labels when they are too close to each other.
I'm printing partial labels, but I don't want to force all so the final render 
won't be cluttered.
Because of the partial labels, sometimes two adjacent tiles have a partial 
rendered, but not on the other and it results in half missing labels. I know 
it's because MapServer tries to avoid overlaps and hides some of the labels.

Is there a way to make mapserver render the same labels on different tiles 
other than specifying explicitly which labels should be visible?

Thanks
Petrovicz
