public sealed class TextChange : IMessage<Document.Types.TextChange>, IEquatable<Document.Types.TextChange>, IDeepCloneable<Document.Types.TextChange>, IBufferMessage, IMessage
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
end index of the text segment are the same, the text change is inserted
before that index.
