Thumbshooter

============

Generates thumbshots of URLs by using Webkit and QT4.

Requirements

============

Please ensure python-qt4 and qt4-webkit is installed.

    apt-get install libqt4-ruby libqt4-webkit

You do also need a running x server. You can use a lightweight

x server by doing "apt-get install xvfb" and enabling it:

    Thumbshooter.use_xvfb = true

Usage

=======

    #Setup options:

    shooter = Thumbshooter.new(

      :screen => '800x600',

      :resize => '600x450',

      :crop => '200x150'

    )

    #Generate thumbnail:

    img = shooter.create('http://github.com/')

    #Write thumbnail to file:

    File.open('thumbshot.png', 'w') {|f| f.write(img) }

**Options for Thumbshooter class:**

    **screen**    

        :screen => 'x'

    example:

        :screen => '800x600'

    **resize**    

        :resize => 'x'

    scaling_option [optional]:

        % - image will be resized proportionaly by percentage 

        # -  image will be resized proportionaly by width

    example:

        :resize => '200x150'

        :resize => '200x150#'

        :resize => '80x50%'

    **crop**    

        :crop => 'x'

    scaling_option [optional]:

        % - image will be cropped proportionaly by percentage

    example:

        :crop => '200x150'

        :crop => '80x50%'

    important:

        size of croped area is based on effect of previous process: 

            :screen if :resize is not set

            :resize if :resize is set

        croped area is always gravity center of image

TO-DO

=======

Croping and resizing image should have more options, similar to "thoughtbot's Paperclip"(http://github.com/thoughtbot/paperclip) .
