• Setting the layer ID in the layer constructor.

  require([
    "esri/layers/ArcGISDynamicMapServiceLayer", ... 
  ], function(ArcGISDynamicMapServiceLayer, ... ) {
    var population = new ArcGISDynamicMapServiceLayer("http://myserver/arcgis/rest/population/MapServer/Layers", {id:"population"});
    ...
  });
  

• Setting the layer ID after a layer is initialized.

  population.id = "population";
  

• Retrieving the layer ID.

  function getMapLayers() {
    for (var j=0, jl=map.layerIds.length; j<jl; j++) {
      var currentLayer = map.getLayer(map.layerIds[j]);
      alert("id: " + currentLayer.id);
    }
  }
  

require([
  "ArcGISImageServiceLayer", ... 
], function(ArcGISImageServiceLayer, ... ) {
  var imageServiceLayer = new ArcGISImageServiceLayer( ... );
  var timeInfo = imageServiceLayer.timeInfo;
  ...
});

myArcGISImageServiceLayer.setBandIds([2,1,0]);

imageServiceLayer.setImageFormat("png8");

require([
  "esri/layers/MosaicRule", ... 
], function(MosaicRule, ... ) {
  var mr = new MosaicRule();
  mr.method = MosaicRule.METHOD_VIEWPOINT;
  mr.viewpoint = inPoint;
  layer.setMosaicRule(mr);
  ...
});

layer.setOpacity(0.5);

require([
  "esri/layers/RasterFunction", ... 
], function(RasterFunction, ... ) {
  var rasterFunction = new RasterFunction();
  rasterFunction.functionName = "Stretch";
  var arguments = {};
  arguments.StretchType= stretch;
  arguments.NumberOfStandardDeviations = parseFloat(dojo.byId('txtSD').value);
  arguments.Gamma =[1.25,2,3.95];
  arguments.Statistics = [[0.2, 222.46, 99.35, 1.64],[ 5.56, 100.345, 45.4, 3.96],[0, 352.37, 172.284, 2]];
  rasterFunction.arguments = arguments; 
  rasterFunction.variableName = "Raster";
  imageServiceLayer.setRenderingRule(rasterFunction);
  ...
});
