:param image: (Required) The image to analyze. See more:
https://googleapis.github.io/google-cloud-python/latest/vision/gapic/v1/types.html#google.cloud.vision_v1.types.Image
:param max_results: Number of results to return.
:param retry: (Optional) A retry object used to retry requests. If `None` is
specified, requests will not be retried.
:param timeout: Number of seconds before timing out.
:param additional_properties: Additional properties to be set on the AnnotateImageRequest. See more:
https://googleapis.github.io/google-cloud-python/latest/vision/gapic/v1/types.html#google.cloud.vision_v1.types.AnnotateImageRequest
:param gcp_conn_id: (Optional) The connection ID used to connect to Google Cloud.
:param impersonation_chain: Optional service account to impersonate using short-term
credentials, or chained list of accounts required to get the access_token
of the last account in the list, which will be impersonated in the request.
If set as a string, the account must grant the originating account
the Service Account Token Creator IAM role.
If set as a sequence, the identities from the list must grant
Service Account Token Creator IAM role to the directly preceding identity, with first
account from the list granting this role to the originating account (templated).
