The EXTRACT action is used by the Textract connector to execute Amazon Textract to extract text and metadata from JPEG and PNG files that are less than 5mb in size.
The Amazon Textract APIs called are the following:
- Detect Document Text API, which joins all LINE block objects with a line separator between them
- Analyze Document API, which performs FORM and TABLES analysis
The IAM user configured to run the Textract services needs to have the textract:DetectDocumentText and textract:AnalyzeDocument permissions.
The authentication for the Textract connector is set using the configuration parameters. For more details, see Textract Configuration Parameters.
