add_raster_layer function

Add a raster layer to a Mapbox GL map

add_raster_layer(
  map,
  id,
  source,
  source_layer = NULL,
  raster_brightness_max = NULL,
  raster_brightness_min = NULL,
  raster_contrast = NULL,
  raster_fade_duration = NULL,
  raster_hue_rotate = NULL,
  raster_opacity = NULL,
  raster_resampling = NULL,
  raster_saturation = NULL,
  visibility = "visible",
  slot = NULL,
  min_zoom = NULL,
  max_zoom = NULL,
  before_id = NULL
)

Arguments

• map: A map object created by the mapboxgl function.
• id: A unique ID for the layer.
• source: The ID of the source.
• source_layer: The source layer (for vector sources).
• raster_brightness_max: The maximum brightness of the image.
• raster_brightness_min: The minimum brightness of the image.
• raster_contrast: Increase or reduce the brightness of the image.
• raster_fade_duration: The duration of the fade-in/fade-out effect.
• raster_hue_rotate: Rotates hues around the color wheel.
• raster_opacity: The opacity at which the raster will be drawn.
• raster_resampling: The resampling/interpolation method to use for overscaling.
• raster_saturation: Increase or reduce the saturation of the image.
• visibility: Whether this layer is displayed.
• slot: An optional slot for layer order.
• min_zoom: The minimum zoom level for the layer.
• max_zoom: The maximum zoom level for the layer.
• before_id: The name of the layer that this layer appears "before", allowing you to insert layers below other layers in your basemap (e.g. labels).

Returns

The modified map object with the new raster layer added.
