Class: TileWMS

ol.source.TileWMS

Layer source for tile data from WMS servers.

new ol.source.TileWMS(opt_options)

src/ol/source/tilewmssource.js, line 35
Name Type Description
options

Tile WMS options.

Name Type Description
attributions Array.<ol.Attribution> | undefined

Attributions.
params Object.<string, *>

WMS request parameters. At least a LAYERS param is required. STYLES is '' by default. VERSION is 1.3.0 by default. WIDTH, HEIGHT, BBOX and CRS (SRS for WMS version < 1.3.0) will be set dynamically.
crossOrigin null | string | undefined

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.
gutter number | undefined

The size in pixels of the gutter around image tiles to ignore. By setting this property to a non-zero value, images will be requested that are wider and taller than the tile size by a value of 2 x gutter. Defaults to zero. Using a non-zero value allows artifacts of rendering at tile edges to be ignored. If you control the WMS service it is recommended to address "artifacts at tile edges" issues by properly configuring the WMS service. For example, MapServer has a tile_map_edge_buffer configuration parameter for this. See http://mapserver.org/output/tile_mode.html.
hidpi boolean | undefined experimental

Use the ol.Map#pixelRatio value when requesting the image from the remote server. Default is true.
logo string | olx.LogoOptions | undefined

Logo.
tileGrid ol.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.
maxZoom number | undefined experimental

Maximum zoom.
projection ol.proj.ProjectionLike experimental

Projection.
serverType ol.source.wms.ServerType | string | undefined experimental

The type of the remote WMS server. Currently only used when hidpi is true. Default is undefined.
tileLoadFunction ol.TileLoadFunctionType | undefined experimental

Optional function to load a tile given a URL.
url string | undefined

WMS service URL.
urls Array.<string> | undefined

WMS service urls. Use this instead of url when the WMS supports multiple urls for GetMap requests.
wrapX boolean | undefined experimental

Whether to wrap the world horizontally. When set to false, only one world will be rendered. When true, tiles will be requested for one world only, but they will be wrapped horizontally to render multiple worlds. The default is true.
