Imagga

Client for Imagga image analytics services API

Installation

Add this line to your application's Gemfile:

gem 'imagga'

And then execute:

$ bundle

Or install it yourself as:

$ gem install imagga

Usage

Set up a client

client = Imagga::Client.new(
  base_uri:   '0.0.0.0',                # IP of the Imagga server
  api_key:    '12345678',               # Your api key
  api_secret: '1234567890123456789'     # Your api secret
)

Extract image information

results = client.extract('http://imagga.com/images/scheme_colors.png')

Extract image information with indexing and extraction options:

results = client.extract(
  [
    Imagga::Image.new(url: 'http://image1', id: '333'),
    Imagga::Image.new(url: 'http://image2')
  ],
  extract_overall_colors: true,
  extract_object_colors: false
)

Check the results, for example:

results.each do |info|                   # iterate over all input image infos
  puts info.object_percentage            # percentage of the central object on image
  info.image_colors.each do |color|      # iterate over all significant colors
    puts color.info                      # 85.89%, rgb: (246,246,246), hex: #f6f6f6 
  end
end

Multi-color search:

client.rank(
  colors: [
    Imagga::RankColor.new(percent: 100, r: 82, g: 37, b: 43)   # use r g b values
    Imagga::RankColor.new(percent: 100, hex: '#336699')        # or use hex
  ],
  type: 'object',
  dist: 6000,
  count: 10
).each do |similarity|
  puts "Distance of #%i is %.4f" % [similarity.id, similarity.dist]  # Distance of #333 is 3581.5500
end

Image crop suggestions:

client.crop(
  [
    'http://image1',                        # Use urls
    Imagga::Image.new(url: 'http://image2') # or image object
  ],
  resolutions: ['100x40','50x100'],         # '100,40,50,100' or '100x40,50x100' instead of array would work also
  no_scaling: true
).each do |crop_info|
  puts crop_info.url
  crop_info.croppings.each do |cropping|
    puts cropping.info
  end
end
