Class ImageAnnotatorClient (2.21.0)

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.

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Functions

BatchAnnotateImages(std::vector< google::cloud::vision::v1::AnnotateImageRequest > const &, Options)

Run image detection and annotation for a batch of images.

Parameters
Name	Description
`requests`	`std::vector< google::cloud::vision::v1::AnnotateImageRequest > const &` Required. Individual image annotation requests for this batch.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::vision::v1::BatchAnnotateImagesResponse >`	the result of the RPC. The response message type (google.cloud.vision.v1.BatchAnnotateImagesResponse) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

BatchAnnotateImages(google::cloud::vision::v1::BatchAnnotateImagesRequest const &, Options)

Run image detection and annotation for a batch of images.

Parameters
Name	Description
`request`	`google::cloud::vision::v1::BatchAnnotateImagesRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.vision.v1.BatchAnnotateImagesRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::vision::v1::BatchAnnotateImagesResponse >`	the result of the RPC. The response message type (google.cloud.vision.v1.BatchAnnotateImagesResponse) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

BatchAnnotateFiles(std::vector< google::cloud::vision::v1::AnnotateFileRequest > const &, Options)

Service that performs image detection and annotation for a batch of files.

Now only "application/pdf", "image/tiff" and "image/gif" are supported.

This service will extract at most 5 (customers can specify which 5 in AnnotateFileRequest.pages) frames (gif) or pages (pdf or tiff) from each file provided and perform detection and annotation for each image extracted.

Parameters
Name	Description
`requests`	`std::vector< google::cloud::vision::v1::AnnotateFileRequest > const &` Required. The list of file annotation requests. Right now we support only one AnnotateFileRequest in BatchAnnotateFilesRequest.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::vision::v1::BatchAnnotateFilesResponse >`	the result of the RPC. The response message type (google.cloud.vision.v1.BatchAnnotateFilesResponse) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

BatchAnnotateFiles(google::cloud::vision::v1::BatchAnnotateFilesRequest const &, Options)

Service that performs image detection and annotation for a batch of files.

Now only "application/pdf", "image/tiff" and "image/gif" are supported.

Parameters
Name	Description
`request`	`google::cloud::vision::v1::BatchAnnotateFilesRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.vision.v1.BatchAnnotateFilesRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::vision::v1::BatchAnnotateFilesResponse >`	the result of the RPC. The response message type (google.cloud.vision.v1.BatchAnnotateFilesResponse) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

AsyncBatchAnnotateImages(std::vector< google::cloud::vision::v1::AnnotateImageRequest > const &, google::cloud::vision::v1::OutputConfig const &, Options)

Run asynchronous image detection and annotation for a list of images.

Progress and results can be retrieved through the google.longrunning.Operations interface. Operation.metadata contains OperationMetadata (metadata). Operation.response contains AsyncBatchAnnotateImagesResponse (results).

This service will write image annotation outputs to json files in customer GCS bucket, each json file containing BatchAnnotateImagesResponse proto.

Parameters
Name	Description
`requests`	`std::vector< google::cloud::vision::v1::AnnotateImageRequest > const &` Required. Individual image annotation requests for this batch.
`output_config`	`google::cloud::vision::v1::OutputConfig const &` Required. The desired output location and metadata (e.g. format).
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

Type Description

future< StatusOr< google::cloud::vision::v1::AsyncBatchAnnotateImagesResponse > >

A future that becomes satisfied when the LRO (Long Running Operation) completes or the polling policy in effect for this call is exhausted. The future is satisfied with an error if the LRO completes with an error or the polling policy is exhausted. In this case the StatusOr returned by the future contains the error. If the LRO completes successfully the value of the future contains the LRO's result. For this RPC the result is a google.cloud.vision.v1.AsyncBatchAnnotateImagesResponse proto message. The C++ class representing this message is created by Protobuf, using the Protobuf mapping rules.
