FILE: sample_analyze_identity_documents.py
DESCRIPTION:
This sample demonstrates how to analyze an identity document.
See fields found on identity documents here:
https://aka.ms/azsdk/documentintelligence/iddocumentfieldschema
USAGE:
python sample_analyze_identity_documents.py
Set the environment variables with your own values before running the sample:
1) DOCUMENTINTELLIGENCE_ENDPOINT - the endpoint to your Document Intelligence resource.
2) DOCUMENTINTELLIGENCE_API_KEY - your Document Intelligence API key.
