Mike: Although this is just on the wishlist at the moment what I'm thinking is feature level, that is it would be applied when an individual feature is drawn. The class or style issue is a matter of where the value is set.
Steve >>> Mike Leahy <[EMAIL PROTECTED]> 11/30/2006 10:39:18 PM >>> Hello list, As far as I can tell, transparency in MapServer is currently only available at the layer level. I'm working on some data that would benefit from being able to view overlapping features (within a single and/or multiple layers) using transparency to reveal density of coverage of certain features (i.e., the more shapes that overlap a given area, the darker the colour). This works great in some tools (e.g., QGis), but it doesn't work so well in mapserver, as overlapping shapes within a single layer end up looking like a single polygon. It seems that at the moment the only workaround would be to have a separate for each individual shape...or use varying hatched styles to fill the polygons. I saw on this page (http://mapserver.gis.umn.edu/development/release_plans/mapserver_5_0) that class or style-level transparency is proposed for 5.0. Out of interest, will this be equivalent to feature-level, or would I have to add individual classes for every feature in a given layer? I suspect the latter, but I'm curious to know if feature-level transparency is on the radar for future development. Thanks for any info... Mike
