Type Definitions

Options{Object}

Properties:
Name Type Argument Default Description
className string <optional>
'ol-layer'

A CSS class name to set to the layer element.

opacity number <optional>
1

Opacity (0, 1).

visible boolean <optional>
true

Visibility.

extent Extent <optional>

The bounding extent for layer rendering. The layer will not be rendered outside of this extent.

zIndex number <optional>

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 <optional>

The minimum resolution (inclusive) at which this layer will be visible.

maxResolution number <optional>

The maximum resolution (exclusive) below which this layer will be visible.

minZoom number <optional>

The minimum view zoom level (exclusive) above which this layer will be visible.

maxZoom number <optional>

The maximum view zoom level (inclusive) at which this layer will be visible.

renderOrder OrderFunction <optional>

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 <optional>
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 <optional>

Source.

map Map <optional>

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 <optional>
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.

style StyleLike | null <optional>

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 <optional>
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, *> <optional>

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