import Layer from './Layer.js';
/**
* @typedef {Object} Options
* @property {string} [className='ol-layer'] A CSS class name to set to the layer element.
* @property {number} [opacity=1] Opacity (0, 1).
* @property {boolean} [visible=true] Visibility.
* @property {import("../extent.js").Extent} [extent] The bounding extent for layer rendering. The layer will not be
* rendered outside of this extent.
* @property {number} [zIndex] 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.
* @property {number} [minResolution] The minimum resolution (inclusive) at which this layer will be
* visible.
* @property {number} [maxResolution] The maximum resolution (exclusive) below which this layer will
* be visible.
* @property {import("../PluggableMap.js").default} [map] 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 {@link module:ol/Map#addLayer}.
* @property {import("../source/Image.js").default} [source] Source for this layer.

/**
* @classdesc

* Note that any property set in the options is set as a {@link module:ol/Object~BaseObject}
* property on the layer object; for example, setting `title: 'My Title'` in the
* options means that `title` is observable, and has get/set accessors.
