Reference documentation and code samples for the Cloud Document AI v1 API class Document.Types.TextChange.
This message is used for text changes aka. OCR corrections.
public Document.Types.TextAnchor TextAnchor { get; set; }
Provenance of the correction.
Text anchor indexing into the
[Document.text][google.cloud.documentai.v1.Document.text]. There can
only be a single TextAnchor.text_segments element. If the start and
