Instance Method Details
#bounds ⇒ Array<Vertex>
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 rotated 180 degrees around the top-left corner it becomes: 2----3 | | 1----0 and the vertice order will still be (0, 1, 2, 3).
