Re: [mapserver-users] dynamically added shapes and their values
Dan, I considered this solution, as well as (Steve) creating a layer for each classification. maybe you are right, despite I must to generate a different file for each user-session: other garbage in tmp dir... :) possibility of apply a style to a single feature can be a great functionality for further releases... what about the STYLEITEM? http://mapserver.org/mapfile/layer.html?highlight=styleitem http://mapserver.org/mapscript/mapscript.html?highlight=styleitem --- thanks all bye ..pg -- Pietro Giannini Bytewise srl - Area GIS 41°50'38.58N 12°29'13.39E On Mer, Gennaio 21, 2009 22:09, Dan Little wrote: Totally spit balling...

Re: [mapserver-users] dynamically added shapes and their values
Steve, I think however it would be quite an easy to suppress the whichitems functionality for the inline layers and expose msLayerSetItems to the SWIG interface so as to achieve the desired effect.
