) -> StartDocumentTextDetectionResponse
Starts the asynchronous detection of text in a document. Amazon Textract can detect lines of text and the words that make up a line of text.
StartDocumentTextDetection can analyze text in documents that are in JPEG, PNG, TIFF, and PDF format. The documents are stored in an Amazon S3 bucket. Use DocumentLocation to specify the bucket name and file name of the document.
StartDocumentTextDetection returns a job identifier (JobId) that you use to get the results of the operation. When text detection is finished, Amazon Textract publishes a completion status to the Amazon Simple Notification Service (Amazon SNS) topic that you specify in NotificationChannel. To get the results of the text detection operation, first check that the status value published to the Amazon SNS topic is SUCCEEDED. If so, call GetDocumentTextDetection, and pass the job identifier (JobId) from the initial call to StartDocumentTextDetection.
For more information, see Document Text Detection.
Parameters:
-
document_location(DocumentLocation) –The location of the document to be processed.
-
client_request_token(Optional[ClientRequestToken], default:None) –The idempotent token that's used to identify the start request. If you use the same token with multiple
StartDocumentTextDetectionrequests, the sameJobIdis returned. UseClientRequestTokento prevent the same job from being accidentally started more than once. For more information, see Calling Amazon Textract Asynchronous Operations. -
job_tag(Optional[JobTag], default:None) –An identifier that you specify that's included in the completion notification published to the Amazon SNS topic. For example, you can use
JobTagto identify the type of document that the completion notification corresponds to (such as a tax form or a receipt). -
notification_channel(Optional[NotificationChannel], default:None) –The Amazon SNS topic ARN that you want Amazon Textract to publish the completion status of the operation to.
-
output_config(Optional[OutputConfig], default:None) –Sets if the output will go to a customer defined bucket. By default Amazon Textract will save the results internally to be accessed with the GetDocumentTextDetection operation.
-
kms_key_id(Optional[KMSKeyId], default:None) –The KMS key used to encrypt the inference results. This can be in either Key ID or Key Alias format. When a KMS key is provided, the KMS key will be used for server-side encryption of the objects in the customer bucket. When this parameter is not enabled, the result will be encrypted server side,using SSE-S3.
Raises:
-
AccessDeniedException–You aren't authorized to perform the action. Use the Amazon Resource Name (ARN) of an authorized user or IAM role to perform the operation.
-
BadDocumentException–Amazon Textract isn't able to read the document. For more information on the document limits in Amazon Textract, see Hard limits.
-
DocumentTooLargeException–The document can't be processed because it's too large. The maximum document size for synchronous operations 10 MB. The maximum document size for asynchronous operations is 500 MB for PDF files.
-
IdempotentParameterMismatchException–A
ClientRequestTokeninput parameter was reused with an operation, but at least one of the other input parameters is different from the previous call to the operation. -
InternalServerError–Amazon Textract experienced a service issue. Try your call again.
-
InvalidKMSKeyException–Indicates you do not have decrypt permissions with the KMS key entered, or the KMS key was entered incorrectly.
-
InvalidParameterException–An input parameter violated a constraint. For example, in synchronous operations, an
InvalidParameterExceptionexception occurs when neither of theS3ObjectorBytesvalues are supplied in theDocumentrequest parameter. Validate your parameter before calling the API operation again. -
InvalidS3ObjectException–Amazon Textract is unable to access the S3 object that's specified in the request. for more information, Configure Access to Amazon S3 For troubleshooting information, see Troubleshooting Amazon S3
-
LimitExceededException–An Amazon Textract service limit was exceeded. For example, if you start too many asynchronous jobs concurrently, calls to start operations (
StartDocumentTextDetection, for example) raise a LimitExceededException exception (HTTP status code: 400) until the number of concurrently running jobs is below the Amazon Textract service limit. -
ProvisionedThroughputExceededException–The number of requests exceeded your throughput limit. If you want to increase this limit, contact Amazon Textract.
-
ThrottlingException–Amazon Textract is temporarily unable to process the request. Try your call again.
-
UnsupportedDocumentException–The format of the input document isn't supported. Documents for operations can be in PNG, JPEG, PDF, or TIFF format.
-
UnknownServiceError–The service returned an error code this client does not model.
