# Pixelated Avatar Generator [![Travis CI Status](https://api.travis-ci.org/ExcaliburZero/pixelated-avatar-generator.svg)](https://travis-ci.org/ExcaliburZero/pixelated-avatar-generator) [![Coverage Status](https://coveralls.io/repos/github/ExcaliburZero/pixelated-avatar-generator/badge.svg?branch=master)](https://coveralls.io/github/ExcaliburZero/pixelated-avatar-generator?branch=master)
Pixelated Avatar Generator is a Haskell library and application for generating pixelated avatar images from seed values.

```haskell
import Graphics.Avatars.Pixelated

createAndSaveAvatar :: String -> FilePath -> IO ()
createAndSaveAvatar s path = saveAvatar avatar path
  where avatar = scaleAvatar 32 $ generateAvatar seed
        seed   = createSeed s
```

![An example of an avatar generated by the library.](example_image.png)

## Executable
An example executable program that uses the library is also provided. It creates an avatar from a given seed string and saves the created `.png` image to a given file location.

The executable can be compiled by running the following command:

```
$ stack build
```

The executable can then by run by running it with `stack exec` and providing it the desired filepath of the output file including the `.png` extension and a random seed string.

```
$ stack exec pixelated-avatar-generator image.png "Hello, World"
Creating avatar at image.png
