#initialize(service_path: SERVICE_ADDRESS, port: DEFAULT_SERVICE_PORT, channel: nil, chan_creds: nil, scopes: ALL_SCOPES, client_config: {}, timeout: DEFAULT_TIMEOUT, app_name: nil, app_version: nil, lib_name: nil, lib_version: "") ⇒ ImageAnnotatorClient

Returns a new instance of ImageAnnotatorClient

Parameters:

  • service_path (String) —

    The domain name of the API remote host.

  • port (Integer) —

    The port on which to connect to the remote host.

  • channel (Channel) —

    A Channel object through which to make calls.

  • chan_creds (Grpc::ChannelCredentials) —

    A ChannelCredentials for the setting up the RPC client.

  • client_config (Hash) —

    A Hash for call options for each method. See Google::Gax#construct_settings for the structure of this data. Falls back to the default config if not specified or the specified config is missing data points.

  • timeout (Numeric) —

Instance Method Details

#batch_annotate_images(requests, options: nil) ⇒ Google::Cloud::Vision::V1::BatchAnnotateImagesResponse

Run image detection and annotation for a batch of images.

Examples:

require "google/cloud/vision/v1/image_annotator_client"

ImageAnnotatorClient = Google::Cloud::Vision::V1::ImageAnnotatorClient

image_annotator_client = ImageAnnotatorClient.new
requests = []
response = image_annotator_client.batch_annotate_images(requests)

Parameters:

  • requests (Array<Google::Cloud::Vision::V1::AnnotateImageRequest>) —

    Individual image annotation requests for this batch.

  • options (Google::Gax::CallOptions) —

    Overrides the default settings for this call, e.g, timeout, retries, etc.

Returns:

Raises:

  • (Google::Gax::GaxError) —

    if the RPC is aborted.
