Optional
params: JLatitudeAndZoomif passed will use the given values for latitude and zoom, else use map current values
// returns the current map scale
JMap.Map.getScaleDenominator()
// returns the map scale for given map latitude=45.5 and zoom level = 4
JMap.Map.getScaleDenominator({
latitude: 45.5,
zoom: 4
})
JMap.Map.getScaleDenominator
Returns the map scale denominator, depending on screen DPI, latitude, and zoom level.
For instance if the scale is "1 : 12959346", the denominator is the number 12959346.
if params is passed will use the given values for latitude (center of the map) and zoom, else use map current ones.
Note: screen DPI is fixed.
