Create screenshots or previews of web pages using Gastly. Under the hood [Phantom.js](https://github.com/ariya/phantomjs/) and [MiniMagick](https://github.com/minimagick/minimagick).

Gastly, I choose you!

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'gastly'
```

And then execute:

$ bundle

Or install it yourself as:

$ gem install gastly

## Usage

```ruby
Gastly.capture('http://google.com', 'output.png')
```

It's also possible to further customize the creation of screenshots and further processing of the resulting image:

```ruby
screenshot = Gastly.screenshot('http://google.com')
screenshot.selector = '#hplogo' # By default, the full screen is captured
screenshot.browser_width = 1280 # Default: 1440px
screenshot.browser_height = 780 # Default: 900px
screenshot.timeout = 1000 # Default: 0 seconds
screenshot.cookies = { user_id: 1, auth_token: 'abcd' } # If you need
screenshot.proxy_host = '10.10.10.1' # If you want to use a http proxy
screenshot.proxy_port = '8080'
screenshot.phantomjs_options = '--ignore-ssl-errors=true'
image = screenshot.capture
```

Or

```ruby
screenshot = Gastly.screenshot('http://google.com', selector: '#hplogo', timeout: 1000)
image = screenshot.capture
```

You can resize, crop or change the format of the screenshot:

```ruby
image = screenshot.capture
image.crop(width: 250, height: 250, x: 10, y: 0) # Crop with an offset
image.resize(width: 110, height: 110) # Creates a preview of the web page
image.format('png')
image.save('output.png')
```

## Development

After checking out the repo, run `bin/setup` to install dependencies. Then, run `bin/console` for an interactive prompt that will allow you to experiment.
