Type Definitions

Options{Object}

Properties:
Name Type Argument Default Description
attributions module:ol/source/Source~AttributionLike <optional>

Attributions.
attributionsCollapsible boolean <optional>
 true

Attributions are collapsible.
cacheSize number <optional>

Tile cache size. The default depends on the screen size. Will increase if too small.
crossOrigin null | string <optional>

The crossOrigin attribute for loaded images. Note that you must provide a crossOrigin value if you want to access pixel data with the Canvas renderer. See https://developer.mozilla.org/en-US/docs/Web/HTML/CORS_enabled_image for more detail.
opaque boolean <optional>
 true

Whether the layer is opaque.
projection module:ol/proj~ProjectionLike <optional>

Projection. Default is the view projection.
reprojectionErrorThreshold number <optional>
 0.5

Maximum allowed reprojection error (in pixels). Higher values can increase reprojection performance, but decrease precision.
state module:ol/source/State <optional>

Source state.
tileClass Class.<module:ol/ImageTile~ImageTile> <optional>

Class used to instantiate image tiles. Default is module:ol/ImageTile~ImageTile.
tileGrid module:ol/tilegrid/TileGrid~TileGrid <optional>

Tile grid.
tileLoadFunction module:ol/Tile~LoadFunction <optional>

Optional function to load a tile given a URL. The default is

function(imageTile, src) {
  imageTile.getImage().src = src;
};
tilePixelRatio number <optional>
 1

The pixel ratio used by the tile service. For example, if the tile service advertizes 256px by 256px tiles but actually sends 512px by 512px images (for retina/hidpi devices) then tilePixelRatio should be set to 2.
tileUrlFunction module:ol/Tile~UrlFunction <optional>

Optional function to get tile URL given a tile coordinate and the projection.
url string <optional>

URL template. Must include {x}, {y} or {-y}, and {z} placeholders. A {?-?} template pattern, for example subdomain{a-f}.domain.com, may be used instead of defining each one separately in the urls option.
urls Array.<string> <optional>

An array of URL templates.
wrapX boolean <optional>

Whether to wrap the world horizontally. The default, is to request out-of-bounds tiles from the server. When set to false, only one world will be rendered. When set to true, tiles will be requested for one world only, but they will be wrapped horizontally to render multiple worlds.
transition number <optional>

Duration of the opacity transition for rendering. To disable the opacity transition, pass transition: 0.
key string <optional>

Optional tile key for proper cache fetching
zDirection number <optional>
 0

Indicate which resolution should be used by a renderer if the view resolution does not match any resolution of the tile source. If 0, the nearest resolution will be used. If 1, the nearest lower resolution will be used. If -1, the nearest higher resolution will be used.
