[mapserver-users] Label not Displaying at Edge of Map Extent

[Fawcett, David (MNIT)]

Michele,

I am guessing that if you set LABEL PARTIALS to TRUE (or just comment it out), you will see your label.

Subject: [mapserver-users] Label not Displaying at Edge of Map Extent

Hi everyone,

I am having an issue with getting a label to display when it is near the edge of the map extent. From what I have seen, when I attach the style for the icon to the label object, the label does not display. However, if I remove the style for the icon from the label object, it does display. Is this an issue with MapServer 7 or the settings that I have used?

Version Information:
[root at Map18-03 cgi-bin]# ./mapserv -v
MapServer version 7.0.0 OUTPUT=PNG OUTPUT=JPEG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=ICONV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=FASTCGI SUPPORTS=GEOS INPUT=JPEG INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE

Below is the map file to reproduce the issue. Please note that there are two layers - one without the icon style attached, and one with the icon style attached. The layer without the icon style attached has been turned on while the other is off.
