## Installation

Add this line to your application's Gemfile:

```ruby

gem 'wildfire'

```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install wildfire

## Usage

Use it from command line:

```sh

bin/wildfire a4 spec/support/printed-iphones-on-a4.jpg

# => The page was cut and placed at spec/support/big_page.jpg

bin/wildfire printed_screens spec/support/printed-iphones-on-a4.jpg

# => The screens were cut and placed at spec/support/screen_0.jpg,

# spec/support/screen_1.jpg, spec/support/screen_2.jpg, spec/support/screen_3.jpg

```

Use it from Ruby code:

```ruby

  manager = Wildfire::Manager.new(image_path)

  manager.predicted_page_coords

  # => [[0,0], [0, 50], [50, 0], [50, 50]]

  manager.cut_page!(manager.predicted_page_coords)

  # => cut_page_path.jpg

  Wildfire::ScreenCutter.new('cut_page_path.jpg').paths

  # => ['screen_1.jpg', 'screen_2.jpg', ...]

```
