add_bitmap: Add bitmap

In mapdeck: Interactive Maps Using 'Mapbox GL JS' and 'Deck.gl'

Description

Adds an image to a map

Usage

add_bitmap(
  map,
  image,
  bounds,
  desaturate = 0,
  transparent_colour = "#000000",
  tint_colour = "#FFFFFF",
  layer_id = NULL,
  update_view = TRUE,
  focus_layer = FALSE
)

Arguments

map	a mapdeck map object
image	url to an image to use on the map
bounds	coordinates of the bounding box of the image [left, bottom, right, top]
desaturate	the desatruation of the bitmap, in range [0,1], 0 being the original colour and 1 being greyscale
transparent_colour	the colour to use for transparent pixels as a hex string
tint_colour	the colour to tint the bipmap by, as a hex string
layer_id	single value specifying an id for the layer. Use this value to distinguish between shape layers of the same type. Layers with the same id are likely to conflict and not plot correctly
update_view	logical indicating if the map should update the bounds to include this layer
focus_layer	logical indicating if the map should update the bounds to only include this layer
