'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.
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
, azIndex
of 0 is assumed for layers that are added to the map'slayers
collection, orInfinity
when the layer'ssetMap()
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:
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
andrenderMode
isvector
, 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 tofalse
, batches will be recreated when no animation is active.updateWhileInteracting
boolean <optional>
false When set to
true
andrenderMode
isvector
, feature batches will be recreated during interactions. See alsoupdateWhileAnimating
.
