class Block
  include ::Google::Protobuf::MessageExts
  extend ::Google::Protobuf::MessageExts::ClassMethods

  # Type of a block (text, image etc) as identified by OCR.
  module BlockType
    # Unknown block type.
    UNKNOWN = 0

    # Regular text block.
    TEXT = 1

    # Table block.

  end
end

#bounding_box ⇒ ::Google::Cloud::Vision::V1::BoundingPoly

Returns The bounding box for the block. 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).

Returns:

  • (::Google::Cloud::Vision::V1::BoundingPoly) —

    The bounding box for the block. 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

    • 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).
