Class v1p2beta1.ImageAnnotatorClient (4.3.2)

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. v1p2beta1

Package

@google-cloud/vision

Constructors

(constructor)(opts, gaxInstance)

constructor(opts?: ClientOptions, gaxInstance?: typeof gax | typeof gax.fallback);

Construct an instance of ImageAnnotatorClient.

Parameters
Name Description
opts ClientOptions
gaxInstance typeof gax | typeof fallback

: loaded instance of google-gax. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: ``` const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new ImageAnnotatorClient({fallback: true}, gax); ```

Methods

asyncBatchAnnotateFiles(request, options)

asyncBatchAnnotateFiles(request?: protos.google.cloud.vision.v1p2beta1.IAsyncBatchAnnotateFilesRequest, options?: CallOptions): Promise<[
        LROperation<protos.google.cloud.vision.v1p2beta1.IAsyncBatchAnnotateFilesResponse, protos.google.cloud.vision.v1p2beta1.IOperationMetadata>,
        protos.google.longrunning.IOperation | undefined,
        {} | undefined
    ]>;

Run async image detection and annotation for a list of generic files (e.g. PDF) 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).

Parameters
Name Description
request IAsyncBatchAnnotateFilesRequest

The request object that will be sent.

options CallOptions

Call options. See CallOptions for more details.

Returns
Type Description
Promise<[ LROperation<protos.google.cloud.vision.v1p2beta1.IAsyncBatchAnnotateFilesResponse, protos.google.cloud.vision.v1p2beta1.IOperationMetadata>, protos.google.longrunning.IOperation | undefined, {} | undefined ]>

{Promise} - The promise which resolves to an array. The first element of the array is an object representing a long running operation. Its promise() method returns a promise you can await for. Please see the documentation for more details and examples.

close()

close(): Promise<void>;

Terminate the gRPC channel and close the client.

The client will no longer be usable and all future behavior is undefined.

Returns
Type Description
Promise<void>

{Promise} A promise that resolves when the client is closed.

getProjectId()

getProjectId(): Promise<string>;

Type Description
Promise<string>

initialize()

initialize(): Promise<{
        [name: string]: Function;
    }>;

Initialize the client. Performs asynchronous operations (such as authentication) and prepares the client. This function will be called automatically when any class method is called for the first time, but if you need to initialize it before calling an actual method, feel free to call initialize() directly.

You can await on this method if you want to make sure the client is initialized.

Returns
Type Description
Promise<{ [name: string]: Function; }>

{Promise} A promise that resolves to an authenticated service stub.
