Avatar-O-Matic

Generate random avatar images on the fly.

The app works by stacking pieces of an avatar (such as background, mouth, eyes) to create a random avatar.

Each option defaults to a random value, but can also be explicitly set.

Inspiration - and most importantly all graphics - are taken from https://github.com/matveyco/8biticon.

Add the following line to your Gemfile:

gem 'avatar-o-matic'

And run bundle install from your shell.

Add the gem to the appropriate file and instantiate the generator.

require 'avatar_o_matic'

generator = AvatarOMatic::Generator.new

generator.size = 96           # Defaults to 400
generator.type = :male        # Image should be of a man, defaults to random
generator.mouth = 10          # Use mouth image #10, defaults to a random value
generator.generate!           # Returns self, thus allowing chained calls
generator.save "avatar.png"

AvatarOMatic::Config.image_lib = "/my/path"   # Defaults to library included in gem

# Peek around in available config:
AvatarOMatic::Generator.properties                  # Available image properties (eg mouth, eye, ...)
AvatarOMatic::Generator.types                       # Available image properties (male or female)
AvatarOMatic::Generator.options_for type, property  # Array of images for this property, of the given type

All image properties are available as attributes on AvatorOMatic::Generator instances, and they all default to a random value.

• background
• face
• clothes
• head
• eye
• mouth

In addition these attributes are also supported:

• type - The image type (currently :male or :female). Good idea to set this before any other property!
• size - Custom size
• image - The generated MiniMagick::Image object (nil before generate! has been invoked)

The image_lib accessor can be set before accessing options_for to supply a custom image library. This library should have the following layout

  root/
  ├── female/
  │   ├── {head|mouth|...}1.png
  │   ├── {head|mouth|...}2.png
  │   └── ...
  └── male/
      ├── {head|mouth|...}1.png
      ├── {head|mouth|...}2.png
      └── ...
