## Instance Methods

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

Run asynchronous image detection and annotation for a list of generic

### Method Details

`annotate(parent, body=None, x__xgafv=None)`

    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.

    Args:
      parent: string, Optional. Target project and location to make a call.

    Format: `projects/{project-id}/locations/{location-id}`.

    If no parent is specified, a region will be chosen automatically.

    Supported location-ids:
        `us`: USA country only,
        `asia`: East asia areas, like Japan, Taiwan,
        `eu`: The European Union.

    Example: `projects/project-A/locations/eu`. (required)
      body: object, The request body.
        The object takes the form of:

`asyncBatchAnnotate(parent, body=None, x__xgafv=None)`

    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).

    Args:
      parent: string, Optional. Target project and location to make a call.

    Format: `projects/{project-id}/locations/{location-id}`.

    If no parent is specified, a region will be chosen automatically.

    Supported location-ids:
        `us`: USA country only,
        `asia`: East asia areas, like Japan, Taiwan,
        `eu`: The European Union.

    Example: `projects/project-A/locations/eu`. (required)
