Hey Martin: I am sure we could do that, we already have a bunch of options to try and pass in current scale/dpi to try and get a visual that matches what is on the screen.
The code is here: https://github.com/geoserver/geoserver/blob/master/src/wms/src/main/java/org/geoserver/wms/GetLegendGraphicRequest.java The important part is: * <tr><td>LAYER </td><td>Required </td><td>Layer for which to produce legend graphic. A layergroup can be specified, too. In this case, STYLE and RULE parameters can have multiple values (separated by commas), one for each of the group layers.</td></tr> So if style and rule are already setup it should be fairly easy to allow layer to have multiple values separated by commas. Indeed internally the code already has: /** The featuretype(s) of the requested LAYER(s) */ private List<FeatureType> layers=new ArrayList<FeatureType>(); So no change to the data structure and logic should be required, just parser and test case. Aside: As long as we are dreaming here I would love to have one that operates like GetFeatureInfo - and includes a reference GetMap complete with BBox (and thus could only show the layers / rules that end up having something on the screen. -- Jody Garnett On 25 September 2015 at 09:48, Martin Davis <mtncl...@gmail.com> wrote: > It looks like GetLegendGraphic only supports requesting a legend for a > single layer.
