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.
gradient	Array.<string>	<optional>	['#00f', '#0ff', '#0f0', '#ff0', '#f00']	The color gradient of the heatmap, specified as an array of CSS color strings.
radius	number	<optional>	8	Radius size in pixels.
blur	number	<optional>	15	Blur size in pixels.
shadow	number	<optional>	250	Shadow size in pixels.
weight	string | function	<optional>	'weight'	The feature attribute to use for the weight or a function that returns a weight from a feature. Weight values should range from 0 to 1 (and values outside will be clamped to that range).
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.
