new TileImage(options)

source/TileImage.js, line 64
Name Type Description
attributions AttributionLike | undefined

Attributions.
attributionsCollapsible boolean (defaults to true)

Attributions are collapsible.
cacheSize number | undefined

Deprecated. Use the cacheSize option on the layer instead.
crossOrigin null | string | undefined

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.
interpolate boolean (defaults to true)

Use interpolated values when resampling. By default, linear interpolation is used when resampling. Set to false to use the nearest neighbor instead.
projection ProjectionLike | undefined

Projection. Default is the view projection.
reprojectionErrorThreshold number (defaults to 0.5)

Maximum allowed reprojection error (in pixels). Higher values can increase reprojection performance, but decrease precision.
state State | undefined

Source state.
tileClass Class<ImageTile> | undefined

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

Tile grid.
tileLoadFunction LoadFunction | undefined

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

function(imageTile, src) {
  imageTile.getImage().src = src;
};
tilePixelRatio number (defaults to 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 UrlFunction | undefined

Deprecated. Use an ImageTile source and provide a function for the url option instead.
url string | undefined

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> | undefined

An array of URL templates.
wrapX boolean | undefined

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 | undefined

Duration of the opacity transition for rendering. To disable the opacity transition, pass transition: 0.
key string | undefined

Optional tile key for proper cache fetching
zDirection number | NearestDirectionFunction (defaults to 0)

Choose whether to use tiles with a higher or lower zoom level when between integer zoom levels. See getZForResolution.
Deprecated
  • Use the ol/source/ImageTile.js instead.
