Installation

Add this line to your application's Gemfile:

gem 'gastly'

And then execute:

$ bundle

Or install it yourself as:

$ gem install gastly

Usage

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

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

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

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

You can resize or change the format of the screenshot:

image = screenshot.capture
image.resize(width: 110, height: 110) # Creates a previews of web-page
image.format('png')
image.save('output.png')
