InheritanceLOD Inheritance flash.events.EventDispatcher

Levels of detail (LOD) for a TiledMapServiceLayer. Each LOD corresponds to a map at a given scale or resolution. Both resolution and scale are required fields. LOD's are automatically sorted based on scale, so setting level isn't necessary.

Constructor Detail
LOD()Constructor
public function LOD(level:Number, resolution:Number, scale:Number)

Creates a new LOD object.

Parameters
level:Number (default = NaN) — ID for each level.
 
resolution:Number (default = NaN) — Resolution in map units of each pixel in a tile for each level.
 
scale:Number (default = NaN) — Scale for each level.
Examples
ActionScript code to add map levels (note: tiled layers will only show at scales they were created for): 
 var lods:Array = myMap.lods;
 lods.push( new LOD( NaN, 0.6, 3000) );
 lods.push( new LOD( NaN, 0.3, 1500) );
 lods.push( new LOD( NaN, 0.1, 500) );
