I am using leaflet.js , heatmap plugin.
There is one tiny class called L.heatLayer (source code https://github.com/Leaflet/Leaflet.heat/blob/gh-pages/src/HeatLayer.js)
There is no option for opacity
The options are only
options: {
maxZoom: 18,
radius: 25,
blur: 15,
max: 1.0},
Is there any way I can control the opacity using this leaflet.js heatLayer ? Thank you very much
