Import PNG textures for overlays

Source: R/get_image_overlay.R

This is an extremely thin wrapper for readPNG, in order for users to not realize they even needed png for this package's functionality at all.

load_overlay(filename)

Arguments

filename

The path to the PNG file to be imported

Value

A matrix of values provided by readPNG

Examples

if (FALSE) {
bbox <- get_centroid_bounding_box(c(
  "lat" = 44.121268,
  "lng" = -73.903734
),
distance = 10
)

overlay_file <- tempfile("overlay_file", fileext = ".png")
get_image_overlay(bbox,
  save.png = TRUE,
  png.filename = overlay_file,
  overlay = "World_Imagery"
)
overlay <- load_overlay(overlay_file)
}
