Signature Detection

As of November 21st, Textract now supports signature detection as part of its document analysis API. This allows you to programmatically verify that a document is signed before proceeding with your data processing workflow.

Installation

To begin, install the amazon-textract-textractor package using pip.

pip install amazon-textract-textractor

There are various sets of dependencies available to tailor your installation to your use case. The base package will have sensible default, but you may want to install the PDF extra dependencies if your workflow uses PDFs with pip install amazon-textract-textractor[pdf]. You can read more on extra dependencies in the documentation
