Properties:
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 acrossOrigin
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
(defaults to 'EPSG:3857')Projection.
reprojectionErrorThreshold
number
(defaults to 0.5)Maximum allowed reprojection error (in pixels). Higher values can increase reprojection performance, but decrease precision.
maxZoom
number
(defaults to 42)Optional max zoom level. Not used if
tileGrid
is provided.minZoom
number
(defaults to 0)Optional min zoom level. Not used if
tileGrid
is provided.maxResolution
number | undefined Optional tile grid resolution at level zero. Not used if
tileGrid
is provided.tileGrid
TileGrid | undefined Tile grid.
tileLoadFunction
LoadFunction | undefined Deprecated. Use an ImageTile source with a loader instead. 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 to2
.tileSize
number | Size
(defaults to [256, 256])The tile size used by the tile service. Not used if
tileGrid
is provided.gutter
number
(defaults to 0)The size in pixels of the gutter around image tiles to ignore. This allows artifacts of rendering at tile edges to be ignored. Supported images should be wider and taller than the tile size by a value of
2 x gutter
.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 examplesubdomain{a-f}.domain.com
, may be used instead of defining each one separately in theurls
option.urls
Array.<string> | undefined Deprecated. Use an ImageTile source and provide an array of URLs for the url option instead.
wrapX
boolean
(defaults to true)Whether to wrap the world horizontally.
transition
number
(defaults to 250)Duration of the opacity transition for rendering. To disable the opacity transition, pass
transition: 0
.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
.
