public sealed class NormalizedBoundingPoly : IMessage<NormalizedBoundingPoly>, IEquatable<NormalizedBoundingPoly>, IDeepCloneable<NormalizedBoundingPoly>, IBufferMessage, IMessage
Reference documentation and code samples for the Google Cloud Video Intelligence v1 API class NormalizedBoundingPoly.
Normalized bounding polygon for text (that might not be aligned with axis).
Contains list of the corner points in clockwise order starting from
top-left corner. For example, for a rectangular bounding box:
When the text is horizontal it might look like:
0----1
| |
3----2
When it's clockwise rotated 180 degrees around the top-left corner it
becomes:
2----3
| |
1----0
and the vertex order will still be (0, 1, 2, 3). Note that values can be less
than 0, or greater than 1 due to trignometric calculations for location of
the box.
