I have been trying to understand how LeafletJS determines distances between two points in a layer. I am trying to implement the custom scale plugin, (and have done so successfully) on a static tiled image using the leaflet deepzoom tilelayer plugin.
Added Information
Using CRS.Simple, the image zoom is adjusted by powers of 2 by the looks of it:

- DPI
- tile size (256 x 256 pixels)
- map size in pixels (bounds of the image)
- leaflet zoom level
- size of image in the real world
