| Name | Description |
data |
array
Optional. Data for populating the Message object. |
↳ property |
TextAnnotation\TextProperty
Additional information detected for the symbol. |
↳ bounding_box |
BoundingPoly
The bounding box for the symbol. The vertices are in the order of top-left, top-right, bottom-right, bottom-left. When a rotation of the bounding box is detected the rotation is represented as around the top-left corner as defined when the text is read in the 'natural' orientation. For example: * * when the text is horizontal it might look like: 0----1 | | 3----2 * * when it's 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). |
↳ text |
