|
||||
- v1.4.2 - add NVG layer capability
|
||||
- v1.4.1 - let `msg.payload.popup` set the popup contents.
|
||||

The geojson features may contain a `properties` property. That may also include a `style` with properties - stroke, stroke-width, stroke-opacity, fill, fill-opacity. Any other properties will be listed in the popup.
|

|
||||
The `opt` property is optional. See the <a href="https://leafletjs.com/examples/geojson/">Leaflet geojson docs</a> for more info on possible options. Note: only simple options are supported as functions cannot be serialised.
|
||||
|
||||
The `fit` property is optional. If present the map will automatically zoom to fit the area relevant to the geojson.
|

see http://leafletjs.com/examples/geojson/ for more details about options for opt.

#### To add a new KML, GPX, or TOPOJSON overlay

As per the geojson overlay you can also inject a KML layer or TOPOJSON layer. The syntax is the same but with either a `kml` property - containing the KML string - or a `topojson` property containing the topojson.

For GPX and KML layers, it is possible to define which icon to use for point markers by adding the
|

following properties to `msg.payload.command.map`:
|
||||
- **icon** : <a href="http://fortawesome.github.io/Font-Awesome/icons/" target="mapinfo">font awesome</a> icon name.
|
||||
- **icon** : <a href="https://fontawesome.com/v4.7.0/icons/" target="mapinfo">font awesome</a> icon name.
|
||||
- **iconColor** : Standard CSS colour name or #rrggbb hex value.
|
||||
|
||||
Again the `fit` property can be added to make the map zoom to the relevant area.
