Type Definitions

Options{Object}

Properties:

Name	Type	Description
`attributions`	AttributionLike \| undefined	Attributions.
`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 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.
`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. `http://my.zoomify.info/IMAGE.TIF/`. A URL template must include `{TileGroup}`, `{x}`, `{y}`, and `{z}` placeholders, e.g. `http://my.zoomify.info/IMAGE.TIF/{TileGroup}/{z}-{x}-{y}.jpg`. Internet Imaging Protocol (IIP) with JTL extension can be also used with `{tileIndex}` and `{z}` placeholders, e.g. `http://my.zoomify.info?FIF=IMAGE.TIF&JTL={z},{tileIndex}`. A `{?-?}` template pattern, for example `subdomain{a-f}.domain.com`, 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	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`.
