HexBinLayer that Extends SVG

[ssontag55]

Any suggestion on this one?

@Igor-Vladyka happy to submit a PR or separate request if needed. Thanks for the proj.

L.Control.BrowserPrint.Utils.registerRenderer(L.HexbinLayer,"L.HexbinLayer",function(layer, options) {
      var hexLayer = L.hexbinLayer(layer.options);
      this.hexLayer.data(layer._data);
      return hexLayer;
    });

L.Control.BrowserPrint.Utils.registerLayer(L.HexbinLayer, "L.HexbinLayer",function(layer) {
      var hexLayer = L.hexbinLayer(layer.options);
      this.hexLayer.data(layer._data);
      return hexLayer;
    });

Hi, here 'HexBinLayer that Extends SVG' is basically a new renderer, so you have to only register renderer.
All layers will be rendered with hexbin renderer. Also, for renderer there is only one param inside builder function, that is options.
L.Control.BrowserPrint.Utils.registerRenderer(L.HexbinLayer,"L.HexbinLayer")

Thanks, works for downloading to image, but the print option doesn't register the layer since the data isn't sent to the Hexbin layer class.

Can you provide an full code example to see what's up with that?
One of the options for now is to catch "L.Control.BrowserPrint.Event.PrintStart" event
map.on(L.Control.BrowserPrint.Event.PrintStart, function(e){ ... }); and add data to renderer there.

There is data in the layer on PrePrint but it's removed on Print. See data array:

I'm not sure how it works internally, but you should use it only as a renderer, and not as both(renderer and layer). Therefore: try to remove registerLayer for HexbinLayer, and pass all needed data to it on PrintStart.

And any working example to debug it would be helpfull :)
