opacity number | undefined

This option is an OpenLayer Vector Layer Option.

Opacity (0, 1). Default is 1.
preload number | undefined

This option is an OpenLayer Vector Layer Option.

Preload. Load low-resolution tiles up to preload levels. By default preload is 0, which means no preloading.
map ol.PluggableMap | undefined

This option is an OpenLayer Vector Layer Option.

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 ol.Map#addLayer.
visible boolean | undefined

The bounding extent for layer rendering. The layer will not be rendered outside of this extent.
minResolution number | undefined

This option is an OpenLayer Vector Layer Option.

The minimum resolution (inclusive) at which this layer will be visible.
maxResolution number | undefined

This option is an OpenLayer Vector Layer Option.

The maximum resolution (exclusive) below which this layer will be visible.
useInterimTilesOnError boolean | undefined

This option is an OpenLayer Vector Layer Option.

Use interim tiles on error. Default is true.
declutter boolean | undefined

This option is an OpenLayer Vector Layer Option.

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. Default is false.
zIndex number | undefined

This option is an OpenLayer Vector Layer Option.

The z-index for layer rendering. At rendering time, the layers will be ordered, first by Z-index and then by position. The default Z-index is 0.
