Read colors from GIMP Palette (GPL) files

Description

Given a path or URL to an .gpl file, this function will return a named character vector (if color names are present) of hex RGB colors.

Usage

read_gpl(path, use_names = TRUE, .verbose = FALSE)

Arguments

path	partial or full file path or URL to a GPL file
use_names	add color names to the vector (defaults to TRUE). See NOTE

Note

When using named color palettes in a ggplot2 scale_ context, you must unname, set use_names to FALSE or override their names to map to your own factor levels. Also, Neither Lab nor greyscale colors are supported.

print(gimp16)
show_palette(gimp16)

# from the internet directly
