Reference documentation and code samples for the Cloud Document AI v1beta3 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.v1beta3.Document.text]. There
can only be a single TextAnchor.text_segments element. If the start
and end index of the text segment are the same, the text change is
inserted before that index.
