public virtual Task<Operation> AsyncBatchAnnotateFiles(AsyncBatchAnnotateFilesRequest request, ServerCallContext context)
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).
public virtual Task<Operation> AsyncBatchAnnotateImages(AsyncBatchAnnotateImagesRequest request, ServerCallContext context)
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.
public virtual Task<BatchAnnotateFilesResponse> BatchAnnotateFiles(BatchAnnotateFilesRequest request, ServerCallContext context)
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.
