FILE: sample_recognize_content.py
DESCRIPTION:
This sample demonstrates how to extract text, selection marks, and content information from a document
given through a file.
Note that selection marks returned from begin_recognize_content() do not return the text associated with
the checkbox. For the API to return this information, train a custom model to recognize the checkbox and its text.
See sample_train_model_with_labels.py for more information.
USAGE:
python sample_recognize_content.py
Set the environment variables with your own values before running the sample:
1) AZURE_FORM_RECOGNIZER_ENDPOINT - the endpoint to your Form Recognizer resource.
2) AZURE_FORM_RECOGNIZER_KEY - your Form Recognizer API key
