It has been some time since I have looked at the code that generates the legends, but to my knowledge it simply generates one swatch for each Rule in the style. Unfortunately there are some cases in SLD where multiple Rules for the same feature class are simply necessary (ie, for road casing you usually want to break up the rule across two featuretypestyles to ensure the draw order is correct.) So you may find it useful to make a second style that is more friendly to the legend generator. In the road casing example, you'd have a style for actual rendering with two feature type styles each containing one rule for the stroke, and a legend style with the two strokes in one rule so the legend generator does the right thing.
It would be nice to have the legend generator inspect the rules across feature type styles and take this sort of thing into account. Actually, it's pretty similar to some of the tricks I have to play in the CSS community module so I've been thinking about it a bit, I could give you some notes (and maybe make a Java-friendly API to that code) if you're interested in doing some Java coding to improve the situation. -- David Winslow OpenGeo - http://opengeo.org/ On Mon, Jun 6, 2011 at 2:34 AM, Andrea Aime <[email protected]>wrote: > On Mon, Jun 6, 2011 at 3:58 AM, Antonio Jose SIlva (Toze) > <[email protected]> wrote: > > Hi, > > > > I have an sld file composed by a group with two rules.
