Properties

Property	Details
georeference	The georeference used to place a media in a MediaLayer.
id	A unique identifying string for the layer.
itemId	Optional string containing the item ID of the `Media Layer` item registered on ArcGIS Online or your organization's portal.
layerType	String indicating the layer type. Valid value of this property `MediaLayer`
listMode	To show or hide the layer in the layer list. Valid values: `hide` `show`
maxScale	A number representing the maximum scale at which the layer will be visible. The number is the scale's denominator.
mediaType	Indicates the type of media the url points to. The currently only supported type is `image` in jpeg or png format. It is applicable only when `url` is defined. Valid value of this property `image`
minScale	A number representing the minimum scale at which the layer will be visible. The number is the scale's denominator.
opacity	The degree of transparency applied to the layer on the client side, where 0 is full transparency and 1 is no transparency.
title	A user-friendly string title for the layer that can be used in a table of contents.
url	URL to the media file. The url is relative when the media file is stored as an item resource. It is not applicable when `itemId` is defined. See related `mediaType` property.
visibility	Boolean property determining whether the layer is initially visible in the web scene.
visibilityTimeExtent	Represents time extent that will control when a layer should be visible based on webscene's current time. Visibility time extent only affects the layer visibility and will not filter the data.
