[Cartoweb-users] Get layers icon in LayerReorder plugin

[Oliver Christen]

Hi

The current scale can be easily accessed via the public function 
getCurrentScale in coreplugin Location

you can also use the public function isLayerVisibleAtCurrentScale in 
coreplugin Layers which should pretty much do already what you want.

Oliver
