Overview

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 [ Setting text extraction options].
