## Preparation

### Install imagemagick

This npm-module depends on [imagemagick](http://www.imagemagick.org/) CLI tools.

```

brew install imagemagick

```

e.g. Debian:

```

sudo apt-get install imagemagick

```

Assert ImageMagick is installed:

```

$convert --version

```

## Installation

```

npm install -g image-divider

```

## Usage

1) Put a configuration file like this

`image-divider.js`:

```

module.exports = {

  images: [{

    src: 'path/to/large.png',

    pos: [16, 32],

    size: [16, 16],

    dest: 'path/to/dest/icon-1.png'

  }, {

    src: 'path/to/large.png',

    pos: [16, 48],

    size: [16, 16],

    dest: 'foo/bar/dest/icon-2.png'

  }]

};

```

2) Execute a command

```bash

image-divider --conf path/to/image-divider.js

```

3) Then, two small images are created

```bash

$tree foo/bar/dest

foo/bar/dest

├── icon-1.png

└── icon-2.png

```

Note:

- `--conf, -c` option

  - Set a path to configuration file

  - Use `./image-divider.js` if it is not set
