mapbox 线条发光效果 发光（如何实现 ）？已实现

这种效果如何实现的

这个是我由两个图层做出效果 颜色之类的可以修改 （如果想发光更亮就可以用更多图层，更低的透明度，加上模糊程度，最关键的白线色图层要最后再加）

1：先创建一个颜色为绿色 宽度为8的图层 模糊程度可以设置为3

map.addLayer({"id": "route","type": "line","source": {"type": "geojson","data": {"type": "Feature","properties": {},"geometry": {"type": "LineString","coordinates": arr}}},"layout": {"line-join": "round","line-cap": "round"},"paint": {"line-color": "#7DF9A6","line-width": 8,"line-opacity": 0.4}});

2：创建一个颜色为白色 宽度为1的图层 (点睛之笔)

 map.addLayer({"id": "route2","type": "line","source": {"type": "geojson","data": {"type": "Feature","properties": {},"geometry": {"type": "LineString","coordinates": arr}}},"layout": {"line-join": "round","line-cap": "round"},"paint": {"line-color": "#fff","line-width": 1}});
