Type Definitions

Options{Object}

Properties:
Name Type Argument Default Description
opacity number <optional>
1

Opacity (0, 1).

visible boolean <optional>
true

Visibility.

extent module:ol/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.

renderOrder module:ol/render~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.

renderMode module:ol/layer/VectorRenderType | string <optional>
'vector'

Render mode for vector layers:

  • 'image': Vector layers are rendered as images. Great performance, but point symbols and texts are always rotated with the view and pixels are scaled during zoom animations.
  • 'vector': Vector layers are rendered as vectors. Most accurate rendering even during animations, but slower performance.
source module:ol/source/Vector~VectorSource <optional>

Source.

map module:ol/PluggableMap~PluggableMap <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 module:ol/Map#addLayer.

declutter boolean <optional>
false

Declutter images and text. Decluttering is applied to all image and text styles, and the priority is defined by the z-index of the style. Lower z-index means higher priority.

style module:ol/style/Style~StyleLike <optional>

Layer style. See module:ol/style for default style which will be used if this is not defined.

updateWhileAnimating boolean <optional>
false

When set to true and renderMode is vector, feature batches will be recreated during animations. This means that no vectors will be shown clipped, but the setting will have a performance impact for large amounts of vector data. When set to false, batches will be recreated when no animation is active.

updateWhileInteracting boolean <optional>
false

When set to true and renderMode is vector, feature batches will be recreated during interactions. See also updateWhileAnimating.
