## Installation
System requirements

```bash
$ sudo apt-get install -y imagemagick
```

Mac OS X

```bash
$ brew install imagemagick ghostscript
```

Add alchemic_avatar to your list of dependencies in `mix.exs`:
```
def deps do
  [{:alchemic_avatar, "~> 0.1.0"}]
end
```

Ensure alchemic_avatar is started before your application:
```
def application do
  [applications: [:alchemic_avatar]]
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"
```
