Class: TileArcGISRest

ol/source/TileArcGISRest~TileArcGISRest 


import TileArcGISRest from 'ol/source/TileArcGISRest.js';

Layer source for tile data from ArcGIS Rest services. Map and Image Services are supported.

For cached ArcGIS services, better performance is available using the XYZ data source.

new TileArcGISRest(options)

source/TileArcGISRest.js, line 68
Name Type Description
attributions AttributionLike | undefined

Attributions.
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 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.
params Object.<string, *> | undefined

ArcGIS Rest parameters. This field is optional. Service defaults will be used for any fields not specified. FORMAT is PNG32 by default. F is IMAGE by default. TRANSPARENT is true by default. BBOX, SIZE, BBOXSR, and IMAGESR will be set dynamically. Set LAYERS to override the default service layer visibility. See https://developers.arcgis.com/rest/services-reference/export-map.htm for further reference.
hidpi boolean (defaults to true)

Use the ol/Map#pixelRatio value when requesting the image from the remote server.
tileGrid TileGrid | undefined

Tile grid. Base this on the resolutions, tilesize and extent supported by the server. If this is not defined, a default grid will be used: if there is a projection extent, the grid will be based on that; if not, a grid based on a global extent with origin at 0,0 will be used.
projection ProjectionLike | undefined

Projection. Default is the view projection. The projection code must contain a numeric end portion separated by : or the entire code must form a valid ArcGIS SpatialReference definition.
reprojectionErrorThreshold number (defaults to 0.5)

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

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

function(imageTile, src) {
  imageTile.getImage().src = src;
};
url string | undefined

ArcGIS Rest service URL for a Map Service or Image Service. The url should include /MapServer or /ImageServer.
wrapX boolean (defaults to true)

Whether to wrap the world horizontally.
transition number | undefined

Duration of the opacity transition for rendering. To disable the opacity transition, pass transition: 0.
urls Array.<string> | undefined

ArcGIS Rest service urls. Use this instead of url when the ArcGIS Service supports multiple urls for export requests.
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.

Returns:
Revision.

getState(){State} inherited

source/Source.js, line 173

Get the state of the source, see State for possible states.
