ol/layer/WebGLTile


Classes

WebGLTileLayer

Type Definitions

Options{Object}

Properties:
Name Type Argument Default Description
style module:ol/layer/WebGLTile~Style <optional>

Style to apply to the layer.

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, 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.

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.

preload number <optional>
0

Preload. Load low-resolution tiles up to preload levels. 0 means no preloading.

source module:ol/source/Tile~TileSource <optional>

Source for this layer.

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.

useInterimTilesOnError boolean <optional>
true

Use interim tiles on error.

ParsedStyle{Object}

Properties:
Name Type Description
vertexShader string

The vertex shader.

fragmentShader string

The fragment shader.

uniforms Object.<string, module:ol/webgl/Helper~UniformValue>

Uniform definitions.

Style{Object}

Translates tile data to rendered pixels.

Properties:
Name Type Argument Default Description
variables Object.<string, number> <optional>

Style variables. Each variable must hold a number. These variables can be used in the color, brightness, contrast, exposure, saturation and gamma expressions, using the ['var', 'varName'] operator. To update style variables, use the module:ol/layer/WebGLTile~WebGLTileLayer#updateStyleVariables method.

color module:ol/style/expressions~ExpressionValue <optional>

An expression applied to color values.

brightness module:ol/style/expressions~ExpressionValue <optional>
0

Value used to decrease or increase the layer brightness. Values range from -1 to 1.

contrast module:ol/style/expressions~ExpressionValue <optional>
0

Value used to decrease or increase the layer contrast. Values range from -1 to 1.

exposure module:ol/style/expressions~ExpressionValue <optional>
0

Value used to decrease or increase the layer exposure. Values range from -1 to 1.

saturation module:ol/style/expressions~ExpressionValue <optional>
0

Value used to decrease or increase the layer saturation. Values range from -1 to 1.

gamma module:ol/style/expressions~ExpressionValue <optional>
1

Apply a gamma correction to the layer. Values range from 0 to infinity.
