Class ImageAnnotatorClient (3.43.0)

GitHub RepositoryProduct ReferenceREST DocumentationRPC Documentation

Service Description: 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.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (ImageAnnotatorClient imageAnnotatorClient = ImageAnnotatorClient.create()) {
   List<AnnotateImageRequest> requests = new ArrayList<>();
   BatchAnnotateImagesResponse response = imageAnnotatorClient.batchAnnotateImages(requests);
 }
 

Note: close() needs to be called on the ImageAnnotatorClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods
Method Description Method Variants

BatchAnnotateImages

Run image detection and annotation for a batch of images.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • batchAnnotateImages(List<AnnotateImageRequest> requests)

  • batchAnnotateImages(BatchAnnotateImagesRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • batchAnnotateImagesCallable()

AsyncBatchAnnotateFiles

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).

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • asyncBatchAnnotateFilesAsync(List<AsyncAnnotateFileRequest> requests)

  • asyncBatchAnnotateFilesAsync(AsyncBatchAnnotateFilesRequest request)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • asyncBatchAnnotateFilesOperationCallable()

  • asyncBatchAnnotateFilesCallable()

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of ImageAnnotatorSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 ImageAnnotatorSettings imageAnnotatorSettings =
     ImageAnnotatorSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 ImageAnnotatorClient imageAnnotatorClient = ImageAnnotatorClient.create(imageAnnotatorSettings);
 

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 ImageAnnotatorSettings imageAnnotatorSettings =
     ImageAnnotatorSettings.newBuilder().setEndpoint(myEndpoint).build();
 ImageAnnotatorClient imageAnnotatorClient = ImageAnnotatorClient.create(imageAnnotatorSettings);
 

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 ImageAnnotatorSettings imageAnnotatorSettings =
     ImageAnnotatorSettings.newHttpJsonBuilder().build();
 ImageAnnotatorClient imageAnnotatorClient = ImageAnnotatorClient.create(imageAnnotatorSettings);
