FormRecognitionSettings

Settings for FormRecognition. Values fall back through three levels: document → SDK → built-in default. Writes target the document only when set on a document’s settings, otherwise the SDK globally when set on SdkSettings.

from nutrient_sdk import FormRecognitionSettings

Construction

# Per-document override
with Document.open("input.pdf") as doc:
    settings = doc.settings.form_recognition_settings
    settings.some_field = new_value          # mutate fields directly

# SDK-wide default (applies to all documents)
SdkSettings.form_recognition_settings.some_field = new_value

Settings are configured by writing to fields on the returned object. The settings property itself cannot be reassigned — doc.settings.form_recognition_settings = other_settings is rejected.
