Leaflet tile provider with fallback and grey scale

QUESTION

Leaflet tile provider with fallback and grey scale

Asked 2019-May-20 at 08:31

I'm currently using two plugins for leaflet: https://github.com/ghybs/Leaflet.TileLayer.Fallback to allow my map to fall back to higher zoom levels if a tile for the current zoom level is not available. https://github.com/Zverik/leaflet-grayscale to make my background map tiles grey scale. I would like to be able to do both at the same time.

I tried making the grey scale plugin extend the fallback object, but that didn't work.

How can I make leaflet-greyscale rather extend TileLayer.Fallback rather than just TileLayer?

Ideally I want a new FallbackGreyscale object or maybe something like L.tileLayer.fallback.greyscale. But any way in which I can have both fallback and grey scale at the same time would be nice.

Leaflet-grayscale uses an inefficient method to convert the image to grayscale: drawing into a canvas. This is done for compatibility with older browsers. Using this technique makes it work in IE, but complicates compatibility.

If you are only targetting browsers which implement the filter CSS rule, the easiest way to accomplish what you want is to modify the _tileOnError() method of Leaflet.TileLayer.Fallback so it applies a grayscale filter style to the tile, i.e..:
