Type Definitions


Name Type Description
attributions AttributionLike | undefined


cacheSize number | undefined

Initial tile cache size. Will auto-grow to hold at least the number of tiles in the viewport.

crossOrigin null | string | undefined

The crossOrigin attribute for loaded images. Note that you must provide a crossOrigin value you want to access pixel data with the Canvas renderer. See 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


tilePixelRatio number | undefined

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

reprojectionErrorThreshold number
(defaults to 0.5)

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

url string

URL template or base URL of the Zoomify service. A base URL is the fixed part of the URL, excluding the tile group, z, x, and y folder structure, e.g. A URL template must include {TileGroup}, {x}, {y}, and {z} placeholders, e.g.{TileGroup}/{z}-{x}-{y}.jpg. Internet Imaging Protocol (IIP) with JTL extension can be also used with {tileIndex} and {z} placeholders, e.g.{z},{tileIndex}. A {?-?} template pattern, for example subdomain{a-f}, may be used instead of defining each one separately in the urls option.

tierSizeCalculation TierSizeCalculation | undefined

Tier size calculation method: default or truncated.

size Size


extent Extent | undefined

Extent for the TileGrid that is created. Default sets the TileGrid in the fourth quadrant, meaning extent is [0, -height, width, 0]. To change the extent to the first quadrant (the default for OpenLayers 2) set the extent as [0, 0, width, height].

transition number | undefined

Duration of the opacity transition for rendering. To disable the opacity transition, pass transition: 0.

tileSize number
(defaults to 256)

Tile size. Same tile size is used for all zoom levels.

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.
