ArcGISMapImageSublayer class final

A sublayer of an ArcGIS map image layer.

ArcGISMapImageSublayer provides access to layers that comprise an ArcGISMapImageLayer. Once the ArcGISMapImageLayer has loaded, you can obtain its map image sublayers from the ArcGISMapImageLayer.mapImageSublayers collection. You can obtain the ArcGIS map service information for each of these sublayers from the ArcGISSublayer.mapServiceSublayerInfo.

If one of the sublayers is a group layer (where the ArcGISMapServiceSublayerInfo.sublayerType is ArcGISMapServiceSublayerType.groupLayer), it will also have a collection of sublayers. Use ArcGISSublayer.sublayers to obtain the collection of sublayers. If one of these sublayers is a group layer it will also contain a collection of sublayers, and so on.

If you know the sublayer Id, you can create it from the ArcGISMapImageSublayer.new constructor.

Once you have obtained the sublayer, you can change the data that is displayed by the ArcGISMapImageLayer by setting the sublayer's visibility, layer definition expression, and other visual properties such as renderer and scale.
