-- | Provides configuration parameters to override the default actions for
-- extracting text from PDF documents and image files.
--
-- By default, Amazon Comprehend performs the following actions to extract
-- text from files, based on the input file type:
--
-- -   __Word files__ - Amazon Comprehend parser extracts the text.
--
-- -   __Digital PDF files__ - Amazon Comprehend parser extracts the text.
--
-- -   __Image files and scanned PDF files__ - Amazon Comprehend uses the
--     Amazon Textract @DetectDocumentText@ API to extract the text.
--
-- @DocumentReaderConfig@ does not apply to plain text files or Word files.
--
-- For image files and PDF documents, you can override these default
-- actions using the fields listed below. For more information, see
-- <https://docs.aws.amazon.com/comprehend/latest/dg/detecting-cer.html#detecting-cer-pdf Setting text extraction options>.
