Thomas, Thanks yet again. I tried your suggestion and it looks quite nice.
If I may, a related question: is there a change in behavior in use of symbols? I'm fairly certain that the MapServer tutorial example worked under 5.6.3, as did my use of the "tie" symbol. The motivation here is to tease out a potential bug in Mapserver 6.0.0-beta1. - Phil -----Original Message----- From: thomas bonfort [mailto:thomas.bonf...@gmail.com] Sent: Friday, March 11, 2011 6:44 AM To: Anzel, Phil - Fort Collins, CO Cc: mapserver-users@lists.osgeo.org Subject: Re: [mapserver-users] Symbol not showing up in MapServer 6.0.0-beta1 release for a tie symbol you should specify a (negative) GAP. something like: http://www2.terriscope.fr/geocache/wms?LAYERS=osm&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fjpeg&SRS=epsg%3A4326&BBOX=1.34033203125,43.76953125,1.3623046875,43.79150390625&WIDTH=256&HEIGHT=256 is obtained with SYMBOL NAME "rail" TYPE TRUETYPE FONT sc CHARACTER '|' GAP -3 END ...
