Options.

Name Type Default Description
attributions module:ol/source/Source~AttributionLike

Attributions.

cacheSize number 2048

Cache size.

crossOrigin null | string

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.

projection module:ol/proj~ProjectionLike

Projection.

reprojectionErrorThreshold number 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 string

Tier size calculation method: default or truncated.

size module:ol/size~Size

Size of the image.

extent module:ol/extent~Extent

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

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

tileSize number 256

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