Type Definitions

Properties:

Name	Type	Description
className	string (defaults to 'ol-layer')	A CSS class name to set to the layer element.
opacity	number (defaults to 1)	Opacity (0, 1).
visible	boolean (defaults to true)	Visibility.
extent	Extent | undefined	The bounding extent for layer rendering. The layer will not be rendered outside of this extent.
zIndex	number | undefined	The z-index for layer rendering. At rendering time, the layers will be ordered, first by Z-index and then by position. When undefined, a zIndex of 0 is assumed for layers that are added to the map's layers collection, or Infinity when the layer's setMap() method was used.
minResolution	number | undefined	The minimum resolution (inclusive) at which this layer will be visible.
maxResolution	number | undefined	The maximum resolution (exclusive) below which this layer will be visible.
minZoom	number | undefined	The minimum view zoom level (exclusive) above which this layer will be visible.
maxZoom	number | undefined	The maximum view zoom level (inclusive) at which this layer will be visible.
preload	number (defaults to 0)	Preload. Load low-resolution tiles up to preload levels. 0 means no preloading.
source	TileSource | undefined	Source for this layer.
map	Map | undefined	Sets the layer as overlay on a map. The map will not manage this layer in its layers collection, and the layer will be rendered on top. This is useful for temporary layers. The standard way to add a layer to a map and have it managed by the map is to use map.addLayer().
background	BackgroundColor | undefined	Background color for the layer. If not specified, no background will be rendered.
useInterimTilesOnError	boolean (defaults to true)	Deprecated. Use interim tiles on error.
properties	Object.<string, *> | undefined	Arbitrary observable properties. Can be accessed with #get() and #set().
cacheSize	number (defaults to 512)	The internal tile cache size. This needs to be large enough to render two zoom levels worth of tiles.
