'hybrid'
: Polygon and line elements are rendered as images, so pixels are scaled during zoom animations. Point symbols and texts are accurately rendered as vectors and can stay upright on rotated views.'vector'
: Everything is rendered as vectors. Use this mode for improved performance on vector tile layers with only a few rendered features (e.g. for highlighting a subset of features of another layer with the same source).
Properties:
Name Type Argument Default Description className
string <optional>
'ol-layer' A CSS class name to set to the layer element.
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.
minZoom
number <optional>
The minimum view zoom level (exclusive) above which this layer will be visible.
maxZoom
number <optional>
The maximum view zoom level (inclusive) at 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 tile extent used by the renderer when getting features from the vector tile for the rendering or hit-detection. Recommended value: Vector tiles are usually generated with a buffer, so this value should match the largest possible buffer of the used tiles. It should be at least the size of the largest point symbol or line width.
renderMode
module:ol/layer/VectorTileRenderType | string <optional>
'hybrid' Render mode for vector tiles:
source
module:ol/source/VectorTile~VectorTile <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
map.addLayer()
.declutter
boolean <optional>
false Declutter images and text. Decluttering is applied to all image and text styles of all Vector and VectorTile layers that have set this to
true
. The priority is defined by the z-index of the layer, thezIndex
of the style and the render order of features. Higher z-index means higher priority. Within the same z-index, a feature rendered before another has higher priority.style
module:ol/style/Style~StyleLike <optional>
Layer style. See
the style docs
for the default style that will be used if this is not defined.updateWhileAnimating
boolean <optional>
false When set to
true
, 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
, feature batches will be recreated during interactions. See alsoupdateWhileAnimating
.preload
number <optional>
0 Preload. Load low-resolution tiles up to
preload
levels.0
means no preloading.useInterimTilesOnError
boolean <optional>
true Use interim tiles on error.
properties
Object.<string, *> <optional>
Arbitrary observable properties. Can be accessed with
#get()
and#set()
.
