Image
A base class for layers that display cached maps. You would typically work with one or more sub-classes of this class. ImageTiledLayer defines a base class for layers that display tiled map services and cached image services. This is an abstract class that can be derived in a custom class to implement a local tile data scheme. To implement a custom ImageTiledLayer, for example to load your own local tile data, you should derive from this type and supply the data for each tile as it is requested. Additionally, you must supply TileInfo that describes the tiling scheme, and an com.arcgismaps.geometry.Envelope that defines the layer extent.
Implement this class if you want to create a custom tiled layer where the cached images cannot be referenced by a simple URI. If your images can be referenced by a simple URI, you should instead implement ServiceImageTiledLayer.

Properties
The attribution string for the image tiled layer.
Controls how a tile request that returns 'NoData' is resampled. Zooming in can result in tile requests with no tiles at the requested level of detail. In this case, there are options that control what to display where the tile should be including:
Inherited properties
The brightness of the layer.
A flag indicating whether the layer content's visibility can be changed. A flag indicating whether the layer content visibility can be changed. Will return false if an error occurs.
The description for the layer.
The full extent of this layer, which is the extent where all layer data is contained. You can use this to zoom to all of the data contained in this layer. For feature layers, the extent is retrieved from its com.arcgismaps.data.FeatureTable.extent.
The unique identifying string for the layer, as specified in a map or scene. The id is used by other parts of this API to refer to a specific Layer, such as in a set of com.arcgismaps.geotriggers.FeatureFenceParameters or a com.arcgismaps.mapping.floor.FacilityLayerDefinition. If not supplied, all layers will be assigned a unique id when created.
True if the layer supports identify, false otherwise. The value of this property may not be correct until the layer is in a fully loaded state.
The load status.
The maximum scale for the layer. The maximum scale at which this layer is visible. If the map or scene is zoomed in beyond this scale, the layer will not be visible. A value of 0 means there is no maximum scale threshold and the layer will be visible at the smallest scale available for the map or scene. If the value is nil, there is no maximum scale. All of the connected map and scene views will be updated.
The minimum scale for the layer. The minimum scale at which this layer is visible. If the map or scene is zoomed out beyond this scale, the layer will not be visible. A value of 0 means there is no minimum scale threshold and the layer will be visible at the largest scale available for the map or scene. If the value is nil, there is no minimum scale. All of the connected map and scene views will be updated.
A flag indicating whether the layer content participates in the legend. A flag indicating whether the layer content is shown in the legend.
The spatial reference of the layer.
The sub layer contents of a layer content.
A SharedFlow that emits when the visibility of the layer changes.
Functions
Clones the ImageTiledLayer.
Inherited functions
Cancels loading metadata for the Loadable object.
Fetches the list of legend info.
Returns the layer content's effective visibility at the specified scale. Returns the effective layer content visibility. This effective visibility takes care of the effective visibility of the parents at the specified scale. Will return false if an error occurs.
