Class: TileImage

ol.source.TileImage

Base class for sources providing images divided into a tile grid.

new ol.source.TileImage(options) experimental

src/ol/source/tileimagesource.js, line 27
Name Type Description
options

Image tile options.

Name Type Description
attributions Array.<ol.Attribution> | undefined experimental

Attributions.
crossOrigin null | string | undefined experimental

The crossOrigin attribute for loaded images. Note that you must provide a crossOrigin value if you are using the WebGL renderer or 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.
logo string | olx.LogoOptions | undefined experimental

Logo.
opaque boolean | undefined experimental

Whether the layer is opaque.
projection ol.proj.ProjectionLike experimental

Projection.
state ol.source.State | string | undefined experimental

Source state.
tileClass function | undefined experimental

Class used to instantiate image tiles. Default is ol.ImageTile.
tileGrid ol.tilegrid.TileGrid | undefined experimental

Tile grid.
tileLoadFunction ol.TileLoadFunctionType | undefined experimental

Optional function to load a tile given a URL.
tilePixelRatio number | undefined experimental

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. Default is 1.
tileUrlFunction ol.TileUrlFunctionType | undefined experimental

Optional function to get tile URL given a tile coordinate and the projection.
wrapX boolean | undefined experimental

Whether to wrap the world horizontally. The default, undefined, 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.
