     1= Styler =
     2[[ToC]]
     3
     4We need a GUI to allow users to do Styling of different Layers:
     5* Polygon Feature layers
     6* Shapefile layers
     7* Theme layers
     8
     9The Style is stored in the per-config link table with the layer, so that the same data can be styled differently for different users. It is a JSON structure:
     10* https://github.com/flavour/eden/blob/master/modules/s3db/gis.py#L2007
     11
     12== Basic ==
     13* Read current setting
     14* Predefined palette
     15* Updates Layer Setting
     16* Updates All Features in realtime
     17 * http://dev.openlayers.org/docs/files/OpenLayers/Style-js.html
     18 * addRules()
     19 * applySymbolizer()
     20* Initial applying of style to features not possible via feature.layer.style as not yet set
     21* Save of setting occurs with rest of Map save (also provide explicit option within widget or do automatically?)
     22
     23== Advanced ==
     24* http://gxp.opengeo.org/master/examples/histogram.html
     25* Add ability to select colours/opacity/etc:
     26 * http://gxp.opengeo.org/master/examples/symbolizer.html
