Type Definitions

Options{Object}

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.

renderOrder OrderFunction | undefined

Render order. Function to be used when sorting features before rendering. By default features are drawn in the order that they are created. Use null to avoid the sort, but get an undefined draw order.

renderBuffer number
(defaults to 100)

The buffer in pixels around the viewport extent used by the renderer when getting features from the vector source for the rendering or hit-detection. Recommended value: the size of the largest symbol, line width or label.

source VectorSource | undefined

Source.

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().

declutter boolean
(defaults to false)

Declutter images and text on this layer. The priority is defined by the zIndex of the style and the render order of features. Higher z-index means higher priority. Within the same z-index, a feature rendered before another has higher priority. Items will not be decluttered against or together with items on other layers with the same declutter value. If that is needed, use VectorLayer instead.

style StyleLike | null | undefined

Layer style. When set to null, only features that have their own style will be rendered. See Style for the default style which will be used if this is not set.

imageRatio number
(defaults to 1)

Ratio by which the rendered extent should be larger than the viewport extent. A larger ratio avoids cut images during panning, but will cause a decrease in performance.

properties Object.<string, *> | undefined

Arbitrary observable properties. Can be accessed with #get() and #set().
