image_palette() returns a list with two elements:

  • palette_list A list with npal color palettes of class Image.

  • joint An object of class Image with the color palettes

  • proportions The proportion of the entire image corresponding to each color in the palette

  • rgbs The average RGB value for each palette

Examples

# \donttest{
library(pliman)
img <- image_pliman("sev_leaf.jpg")
