client = ::Google::Cloud::Vision::V1p3beta1::ImageAnnotator::Rest::Client.new do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the ImageAnnotator client.

Instance Method Details

#async_batch_annotate_files(request, options = nil) ⇒ ::Gapic::Operation #async_batch_annotate_files(requests: nil) ⇒ ::Gapic::Operation

Run asynchronous image detection and annotation for a list of generic files, such as PDF files, which may contain multiple pages and multiple images per page. Progress and results can be retrieved through the google.longrunning.Operations interface. Operation.metadata contains OperationMetadata (metadata). Operation.response contains AsyncBatchAnnotateFilesResponse (results).

Examples:

Basic example

require "google/cloud/vision/v1p3beta1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Vision::V1p3beta1::ImageAnnotator::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Vision::V1p3beta1::AsyncBatchAnnotateFilesRequest.new

# Call the async_batch_annotate_files method.
result = client.async_batch_annotate_files request

# The returned object is of type Gapic::Operation. You can use it to
# check the status of an operation, cancel it, or wait for results.
# Here is how to wait for a response.
result.wait_until_done! timeout: 60
if result.response?
  p result.response
else
  puts "No response received."
end

Overloads:

  • #async_batch_annotate_files(request, options = nil) ⇒ ::Gapic::Operation

    Pass arguments to async_batch_annotate_files via a request object, either of type AsyncBatchAnnotateFilesRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::Vision::V1p3beta1::AsyncBatchAnnotateFilesRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

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

  • #async_batch_annotate_files(requests: nil) ⇒ ::Gapic::Operation

    Pass arguments to async_batch_annotate_files via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

Yields:

  • (result, operation) —

    Access the result along with the TransportOperation object

Yield Parameters:

  • result (::Gapic::Operation)
  • operation (::Gapic::Rest::TransportOperation)

Returns:

  • (::Gapic::Operation)

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.

#configure {|config| ... } ⇒ Client::Configuration

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.
