end

Configuration

config :alchemic_avatar,
  cache_base_path: "static",             # default is "static"
  colors_palette: :iwanthue,             # default is :google
  weight: 500,                           # default is 300
  annotate_position: "-0+10",            # default is -0+5
  app_name: #your app name(required)

Color palette

We have two color palettes implemented: iwanthue and google.

Each of them have different colors, but the iwanthue also differently calculates the color for specified username.

The google selected will generate the same avatar for both, "Krzysiek" and "ksz2k" usernames given (both of them starts with letter "k"), but iwanthue will calculate it's md5 and then selects color, so there's huge chance that these usernames get different colors.

Usage

AlchemicAvatar.generate "ksz2k", 200
=> "public/system/alchemic_avatar/k/155_206_95/200.png"
