[mapserver-users] issue with partials = false? / labels only being displayed near the center of a map for a single layer (other layers are fine) - MS4W 3.2.7 / Mapserver 7.0.7

[Mark Volz]

Hello,

I am in the process of updating all my maps files to use Mapserver 7.0.7 / MS4W 3.2.7.  I noticed a possible odd issue with PARTIALS=FALSE.  Normally I would expect that PARTIALS False would not label sections if the label falls off the edge of the map.  However in my case for one of the layers in my map file I noticed that only the sections in the center of my map were labeled.  About 60% of the labels I would otherwise expect to be labeled did not appear.  I am not really sure why more of my sections were not labeled.  Here is what I can tell you:


*         I removed the index files (esri and qix) files.  However this should not be an issue because I can see the polygons for sections across the map.

*         The labels on the map are sparse enough that there should not be any label collision issues with other layers on the map.

o   Only the center labels appear even if I turn every other layer off in my map.

*         The map file was upgraded from an older version of mapserver which seemed to work fine.

*         See an example at https://geomoose.lyonco.org/LyonMoose/BadSectionLabels.png

*         All the expected labels appear for other layers regardless if PARTIALS are set to true or not.

*         The map file is relatively simple.



If anyone could help tell my why only the central sections are labeled please let me know.

Thank You!
