BoundingBox

public BoundingPoly BoundingBox { get; set; }

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).
