settings global parameters for GetLegendGraphic

[c.morales]

Hi,

I need to modify for all layers the getLegend Graphic parameteres : width, height.

It is possible to do it by an user from the UI on a layer (for example width 30, height 20) but  i can't find a way to make these parameters global from a localConfig.json setting or from the TOC's plugin  of an application context.

Example of url from a custoised layer done by an user : 

https://portail.sig.rennesmetropole.fr/geoserver/ows?service=WMS&request=GetLegendGraphic&format=image%2Fpng&height=20&width=30&layer=urba_fonc%3Adp&style=&version=1.3.0&SLD_VERSION=1.1.0&LEGEND_OPTIONS=forceLabels%3Aon&SCALE=8531

I tried parameters listed in https://mapstore.geosolutionsgroup.com/mapstore/docs/api/plugins#plugins.TOC 

1-    "legendStyle": { "maxWidth": "250%" } 

On what is referring the %, how to use it to have the same width and height as see before

2-  "WMSLegendOptions":  it's use only geoserver the vendor parameter LEGEND_OPTIONS, (https://docs.geoserver.org/latest/en/user/services/wms/get_legend_graphic/index.html) i tried with columnheight and rowwidth parameters but without effect.

How can i do ?

Hi, 

The configuration you need are  legendWidth  and legendHeight inside layerOptions.legendOptions

cfg: {

   layerOptions: { 

      legendOptions: { legendWidth: 12, legendHeight: 12}

  }

}
I opened this pull request to improve documentation, adding these settings that were missing. 

thank you for sharing.

Thank you vey much, it works well. 

I applied it on our instances in localConfig.json :

"layerOptions": {
   "legendOptions": {
   "scaleDependent": true,
   "legendStyle": {
       "maxWidth": "250%"
    },
  "WMSLegendOptions": "forceLabels:on",
  "legendWidth": 30,
  "legendHeight": 20,
   "legendContainerStyle": {
        "overflowX": "auto"
     }
  } 

},

Hi,

I try to setup a context without TOC enabled, but with floatingLegend addon, and this conf is only available in TOC.

Is there a way to setup it also for FloatingLegend plugin ?

I try to setup an IFrame context that allow to add layers via URL to publish them on partners websites, but legends in FloatingLegend are too small.
