Cloud Vision V1 Client - Class ImageAnnotatorClient (1.7.6)

Reference documentation and code samples for the Cloud Vision V1 Client class ImageAnnotatorClient.

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:

$imageAnnotatorClient = new ImageAnnotatorClient();
try {
    $requests = [];
    $operationResponse = $imageAnnotatorClient->asyncBatchAnnotateFiles($requests);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        $result = $operationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $imageAnnotatorClient->asyncBatchAnnotateFiles($requests);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $imageAnnotatorClient->resumeOperation($operationName, 'asyncBatchAnnotateFiles');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $imageAnnotatorClient->close();
}

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 parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

This service has a new (beta) implementation. See Google\Cloud\Vision\V1\Client\ImageAnnotatorClient to use the new surface.

`↳ transport`	`string\|TransportInterface` The transport used for executing network requests. May be either the string `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object.
