Download a PhyloPic silhouette — get_phylopic

This function downloads a silhouette from the PhyloPic database. With the new API, some functions of the package rphylopic don't work anymore. This function aims to temporary replace the function rphylopic::image_data() as this package seems to be looking for a new maintainer.

get_phylopic_image(uuid, size = 512)

Arguments

uuid: a character of length 1. The UUID (unique taxa identifier in the Phylopic database).
size: an integer of length 1. The size of the PNG to download. An error will be raised in the size is not available.

Value

An array of dimensions red x green x blue x alpha.

Examples

if (FALSE) {
mammals_pic <- get_phylopic_image("8cad2b22-30d3-4cbd-86a3-a6d2d004b201")

## Plot the silhouette ----
ggplot2::ggplot(x = Sepal.Length, y = Sepal.Width, data = iris, 
                geom = "point") +
rphylopic::add_phylopic(mammals_pic, alpha = 1)
}
