Mask support for heatmap layer

[seifer08ms]

Will heatmap.js have a mask support?

Thanks

could you elaborate a bit? do you mean the leaflet layer? any of the maps layers? or the heatmap core library? also what kind of mask support are you looking for? (applying a svg mask onto the exported image could already work)

We want to dynamically hide parts of heat layer by a leaflet polygon mask. For example, we define a ROI with a polygon layer , leaflet will only show parts of heatmap within ROI. If we edit shape of ROI, the leaflet will update the heatmap layer with the mask.

Is it possible to do this now? I would like to show the heatmap inside a mask, but the example doesn't work for me
