      # # Ruby Client for Cloud Vision API ([Alpha](https://github.com/googleapis/google-cloud-ruby#versioning))
      #
      # [Cloud Vision API][Product Documentation]:
      # Integrates Google Vision features, including image labeling, face, logo,
      # and landmark detection, optical character recognition (OCR), and detection
      # of explicit content, into applications.
      # - [Product Documentation][]
      #
      # ## Quick Start
      # In order to use this library, you first need to go through the following
      # steps:
      #
      # 1. [Select or create a Cloud Platform project.](https://console.cloud.google.com/project)
      # 2. [Enable billing for your project.](https://cloud.google.com/billing/docs/how-to/modify-project#enable_billing_for_a_project)
      # 3. [Enable the Cloud Vision API.](https://console.cloud.google.com/apis/library/vision.googleapis.com)
      # 4. [Setup Authentication.](https://googleapis.dev/ruby/google-cloud-vision/latest/file.AUTHENTICATION.html)
      #
      # ### Installation
      # ```
      # $ gem install google-cloud-vision
      # ```
      #
      # ### Preview
      # #### ImageAnnotatorClient
      # ```rb
      # require "google/cloud/vision"
      #
      # image_annotator_client = Google::Cloud::Vision::ImageAnnotator.new(version: :v1)
      # gcs_image_uri = "gs://cloud-samples-data/vision/face_detection/celebrity_recognition/sergey.jpg"
      # source = { gcs_image_uri: gcs_image_uri }
      # image = { source: source }
      # type = :FACE_DETECTION
      # features_element = { type: type }
      # features = [features_element]
      # requests_element = { image: image, features: features }
      # requests = [requests_element]
      # response = image_annotator_client.batch_annotate_images(requests)
      # ```
      #
      # ### Next Steps
      # - Read the [Cloud Vision API Product documentation][Product Documentation]
      #   to learn more about the product and see How-to Guides.
      # - View this [repository's main README](https://github.com/googleapis/google-cloud-ruby/blob/master/README.md)
      #   to see the full list of Cloud APIs that we cover.

      # ## Enabling Logging
      #
      # To enable logging for this library, set the logger for the underlying [gRPC](https://github.com/grpc/grpc/tree/master/src/ruby) library.
      # The logger that you set may be a Ruby stdlib [`Logger`](https://ruby-doc.org/stdlib-2.5.0/libdoc/logger/rdoc/Logger.html) as shown below,
      # or a [`Google::Cloud::Logging::Logger`](https://googleapis.dev/ruby/google-cloud-logging/latest)
      # that will write logs to [Stackdriver Logging](https://cloud.google.com/logging/). See [grpc/logconfig.rb](https://github.com/grpc/grpc/blob/master/src/ruby/lib/grpc/logconfig.rb)
      # and the gRPC [spec_helper.rb](https://github.com/grpc/grpc/blob/master/src/ruby/spec/spec_helper.rb) for additional information.
      #
      # Configuring a Ruby stdlib logger:
      #
      # ```ruby
      # require "logger"
      #
      # module MyLogger
      #   LOGGER = Logger.new $stderr, level: Logger::WARN
      #   def logger
      #     LOGGER
      #   end
      # end
      #
      # # Define a gRPC module-level logger method before grpc/logconfig.rb loads.
      # module GRPC
      #   extend MyLogger
      # end
      # ```
      #

        module ImageAnnotator
          ##
          # Service that performs Google Cloud Vision API detection tasks over client
          # images, such as face, landmark, logo, label, and text detection. The
          # ImageAnnotator service returns detected entities from the images.
