Add a WMS layer — add_wms • geolibre

The layer is rendered as tiled raster from WMS GetMap requests, built exactly as the application's Add Data dialog builds them.

Usage

add_wms(
  map,
  endpoint,
  layers,
  name = "WMS Layer",
  styles = "",
  image_format = "image/png",
  transparent = TRUE,
  tile_size = 256,
  version = "1.1.1",
  style = list(),
  visible = TRUE,
  opacity = 1,
  ...
)

Arguments

map: A GeoLibre widget.
endpoint: WMS service endpoint, the GetMap base URL.
layers: Comma-separated WMS layer name(s).
name: Layer name.
styles: Comma-separated WMS style name(s); empty for the server default.
image_format: WMS image format, for example "image/png".
transparent: Whether to request transparent tiles.
tile_size: Tile size in pixels.
version: WMS protocol version, "1.1.1" or "1.3.0". Version 1.3.0 sends CRS instead of SRS; some servers accept only one version.
style: Named list of GeoLibre style overrides such as fillColor, strokeColor, and strokeWidth.
visible: Whether the layer is initially visible.
opacity: Layer opacity from zero to one.
...: Additional style overrides given as named arguments, merged into style. add_geojson(map, data, fillColor = "red") and add_geojson(map, data, style = list(fillColor = "red")) are equivalent.

Value

The modified widget.

Examples

map <- geolibre() |>
  add_wms(
    "https://example.com/geoserver/wms",
    layers = "topp:states",
    name = "States"
  )
stopifnot(map$x$project$layers[[1]]$type == "wms")
