Documentation

Overview

Package textract provides the client and types for making API requests to Amazon Textract.

Amazon Textract detects and analyzes text in documents and converts it into machine-readable text. This is the API reference documentation for Amazon Textract.

See https://docs.aws.amazon.com/goto/WebAPI/textract-2018-06-27 for more information on this service.

See textract package documentation for more information. https://docs.aws.amazon.com/sdk-for-go/api/service/textract/

Using the Client

To contact Amazon Textract with the SDK use the New function to create a new service client. With that client you can make API requests to the service. These clients are safe to use concurrently.

See the SDK's documentation for more information on how to use the SDK. https://docs.aws.amazon.com/sdk-for-go/api/

See aws.Config documentation for more information on configuring SDK clients. https://docs.aws.amazon.com/sdk-for-go/api/aws/#Config

See the Amazon Textract client Textract for more information on creating client for this service. https://docs.aws.amazon.com/sdk-for-go/api/service/textract/#New

}

A Block represents items that are recognized in a document within a group of pixels close to each other. The information returned in a Block depends on the type of operation. In document-text detection (for example DetectDocumentText), you get information about the detected words and lines of text. In text analysis (for example AnalyzeDocument), you can also get information about the fields, tables and selection elements that are detected in the document.

An array of Block objects is returned by both synchronous and asynchronous operations. In synchronous operations, such as DetectDocumentText, the array of Block objects is the entire set of results. In asynchronous operations, such as GetDocumentAnalysis, the array is returned over one or more responses.

}

The bounding box around the recognized text, key, value, table or table cell on a document page. The left (x-coordinate) and top (y-coordinate) are coordinates that represent the top and left sides of the bounding box. Note that the upper-left corner of the image is the origin (0,0).

The top and left values returned are ratios of the overall document page size. For example, if the input image is 700 x 200 pixels, and the top-left coordinate of the bounding box is 350 x 50 pixels, the API returns a left value of 0.5 (350/700) and a top value of 0.25 (50/200).

The width and height values represent the dimensions of the bounding box as a ratio of the overall document page dimension. For example, if the document page size is 700 x 200 pixels, and the bounding box width is 70 pixels, the width returned is 0.1.

type Document struct {

	// A blob of base-64 encoded documents bytes. The maximum size of a document
	// that's provided in a blob of bytes is 5 MB. The document bytes must be in
	// PNG or JPG format.
	//
	// If you are using an AWS SDK to call Amazon Textract, you might not need to

	// stored in an S3 bucket is 5 MB.
	S3Object *S3Object `type:"structure"`
	// contains filtered or unexported fields
}

The input document, either as bytes or as an S3 object.

You pass image bytes to an Amazon Textract API operation by using the Bytes property. For example, you would use the Bytes property to pass a document loaded from a local file system. Image bytes passed by using the Bytes property must be base64 encoded. Your code might not need to encode document file bytes if you're using an AWS SDK to call Amazon Textract API operations.

You pass images stored in an S3 bucket to an Amazon Textract API operation by using the S3Object property. Documents stored in an S3 bucket don't need to be base64 encoded.

The AWS Region for the S3 bucket that contains the S3 object must match the AWS Region that you use for Amazon Textract operations.

If you use the AWS CLI to call Amazon Textract operations, passing image bytes using the Bytes property isn't supported. You must first upload the document to an Amazon S3 bucket, and then call the operation using the S3Object property.

For Amazon Textract to process an S3 object, the user must have permission to access the S3 object.

func (*Textract) GetDocumentAnalysis

func (c *Textract) GetDocumentAnalysis(input *GetDocumentAnalysisInput) (*GetDocumentAnalysisOutput, error)

GetDocumentAnalysis API operation for Amazon Textract.

Gets the results for an Amazon Textract asynchronous operation that analyzes text in a document.

You start asynchronous text analysis by calling StartDocumentAnalysis, which returns a job identifier (JobId). When the text analysis operation finishes, Amazon Textract publishes a completion status to the Amazon Simple Notification Service (Amazon SNS) topic that's registered in the initial call to StartDocumentAnalysis. 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 GetDocumentAnalysis, and pass the job identifier (JobId) from the initial call to StartDocumentAnalysis.

GetDocumentAnalysis returns an array of Block objects. The following types of information are returned:

  • Words and lines that are related to nearby lines and words. The related information is returned in two Block objects each of type KEY_VALUE_SET: a KEY Block object and a VALUE Block object. For example, Name: Ana Silva Carolina contains a key and value. Name: is the key. Ana Silva Carolina is the value.

  • Table and table cell data. A TABLE Block object contains information about a detected table. A CELL Block object is returned for each cell in a table.

  • Selectable elements such as checkboxes and radio buttons. A SELECTION_ELEMENT Block object contains information about a selectable element.

  • Lines and words of text. A LINE Block object contains one or more WORD Block objects.

Use the MaxResults parameter to limit the number of blocks returned. If there are more results than specified in MaxResults, the value of NextToken in the operation response contains a pagination token for getting the next set of results. To get the next page of results, call GetDocumentAnalysis, and populate the NextToken request parameter with the token value that's returned from the previous call to GetDocumentAnalysis.

For more information, see Document Text Analysis (https://docs.aws.amazon.com/textract/latest/dg/how-it-works-analyzing.html).

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for Amazon Textract's API operation GetDocumentTextDetection for usage and error information.

Returned Error Codes:

  • ErrCodeInvalidParameterException "InvalidParameterException" An input parameter violated a constraint. For example, in synchronous operations, an InvalidParameterException exception occurs when neither of the S3Object or Bytes values are supplied in the Document request parameter. Validate your parameter before calling the API operation again.

  • ErrCodeAccessDeniedException "AccessDeniedException" You aren't authorized to perform the action.

  • ErrCodeProvisionedThroughputExceededException "ProvisionedThroughputExceededException" The number of requests exceeded your throughput limit. If you want to increase this limit, contact Amazon Textract.

  • ErrCodeInvalidJobIdException "InvalidJobIdException" An invalid job identifier was passed to GetDocumentAnalysis or to GetDocumentAnalysis.

  • ErrCodeInternalServerError "InternalServerError" Amazon Textract experienced a service issue. Try your call again.

  • ErrCodeThrottlingException "ThrottlingException" Amazon Textract is temporarily unable to process the request. Try your call again.

func (*Textract) GetDocumentTextDetectionRequest

func (c *Textract) GetDocumentTextDetectionRequest(input *GetDocumentTextDetectionInput) (req *request.Request, output *GetDocumentTextDetectionOutput)

GetDocumentTextDetectionRequest generates a "aws/request.Request" representing the client's request for the GetDocumentTextDetection operation. The "output" return value will be populated with the request's response once the request completes successfully.

Use "Send" method on the returned Request to send the API call to the service. the "output" return value is not valid until after Send returns without error.

See GetDocumentTextDetection for more information on using the GetDocumentTextDetection API call, and error handling.

This method is useful when you want to inject custom logic or configuration into the SDK's request lifecycle. Such as custom headers, or retry logic.

// Example sending a request using the GetDocumentTextDetectionRequest method.
req, resp := client.GetDocumentTextDetectionRequest(params)

err := req.Send()
if err == nil { // resp is now filled
    fmt.Println(resp)
}

func (*Textract) GetDocumentTextDetectionWithContext

func (c *Textract) GetDocumentTextDetectionWithContext(ctx aws.Context, input *GetDocumentTextDetectionInput, opts ...request.Option) (*GetDocumentTextDetectionOutput, error)

GetDocumentTextDetectionWithContext is the same as GetDocumentTextDetection with the addition of the ability to pass a context and additional request options.

See GetDocumentTextDetection for details on how to use this API operation.

The context must be non-nil and will be used for request cancellation. If the context is nil a panic will occur. In the future the SDK may create sub-contexts for http.Requests. See https://golang.org/pkg/context/ for more information on using Contexts.

func (*Textract) StartDocumentAnalysis

func (c *Textract) StartDocumentAnalysis(input *StartDocumentAnalysisInput) (*StartDocumentAnalysisOutput, error)

StartDocumentAnalysis API operation for Amazon Textract.

Starts asynchronous analysis of an input document for relationships between detected items such as key and value pairs, tables, and selection elements.

StartDocumentAnalysis can analyze text in documents that are in JPG, PNG, 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.

StartDocumentAnalysis returns a job identifier (JobId) that you use to get the results of the operation. When text analysis 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 analysis operation, first check that the status value published to the Amazon SNS topic is SUCCEEDED. If so, call GetDocumentAnalysis, and pass the job identifier (JobId) from the initial call to StartDocumentAnalysis.

For more information, see Document Text Analysis (https://docs.aws.amazon.com/textract/latest/dg/how-it-works-analyzing.html).

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for Amazon Textract's API operation StartDocumentAnalysis for usage and error information.

Returned Error Codes:

  • ErrCodeInvalidParameterException "InvalidParameterException" An input parameter violated a constraint. For example, in synchronous operations, an InvalidParameterException exception occurs when neither of the S3Object or Bytes values are supplied in the Document request parameter. Validate your parameter before calling the API operation again.

  • ErrCodeInvalidS3ObjectException "InvalidS3ObjectException" Amazon Textract is unable to access the S3 object that's specified in the request.

  • ErrCodeUnsupportedDocumentException "UnsupportedDocumentException" The format of the input document isn't supported. Amazon Textract supports documents that are .png or .jpg format.

  • ErrCodeDocumentTooLargeException "DocumentTooLargeException" The document can't be processed because it's too large. The maximum document size for synchronous operations 5 MB. The maximum document size for asynchronous operations is 500 MB for PDF format files.

  • ErrCodeBadDocumentException "BadDocumentException" Amazon Textract isn't able to read the document.

  • ErrCodeAccessDeniedException "AccessDeniedException" You aren't authorized to perform the action.

  • ErrCodeProvisionedThroughputExceededException "ProvisionedThroughputExceededException" The number of requests exceeded your throughput limit. If you want to increase this limit, contact Amazon Textract.

  • ErrCodeInternalServerError "InternalServerError" Amazon Textract experienced a service issue. Try your call again.

  • ErrCodeIdempotentParameterMismatchException "IdempotentParameterMismatchException" A ClientRequestToken input parameter was reused with an operation, but at least one of the other input parameters is different from the previous call to the operation.

  • ErrCodeThrottlingException "ThrottlingException" Amazon Textract is temporarily unable to process the request. Try your call again.

  • ErrCodeLimitExceededException "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.
