I see, in the example code, which i know is out of date, but it gives me a starting block for learning this,
roadsStyle.addFeatureTypeStyle(sb.createFeatureTypeStyle(null, sb.createRule(ls2))); http://docs.codehaus.org/display/GEOTOOLS/Putting+everything+together i don't seen a condition being written like anything to do with Filter or Scale, just code saying make sure the road is yellow. I forgot to mention, in this particular function createFeatureTypeStyle(null, sb.createRule(ls2) why would somebody give it the value "null"? because in the javadoc you can give it a typename thanks ajayravichandran wrote: > > Hi > > The general idea is that using a Rule you can control how to render the > feature. > > A Rule has a condition.If the condition is satisfied the Symbolizer > defined > under the rule hold good, so the feature will be drawn based on those > symbolizers.
