public sealed class TextAnnotation : IMessage<TextAnnotation>, IEquatable<TextAnnotation>, IDeepCloneable<TextAnnotation>, IBufferMessage, IMessage
TextAnnotation contains a structured representation of OCR extracted text.
The hierarchy of an OCR extracted text structure is like this:
TextAnnotation -> Page -> Block -> Paragraph -> Word -> Symbol
Each structural component, starting from Page, may further have their own
properties. Properties describe detected languages, breaks etc.. Please refer
to the [TextAnnotation.TextProperty][google.cloud.vision.v1.TextAnnotation.TextProperty] message definition below for more
