Detailed Description

template<typename T>
class ZXing::Quadrilateral< T >

A simple class representing a quadrilateral defined by its four corner points.

It represents a quadrilateral defined by its four corner points: top-left, top-right, bottom-right, and bottom-left. Those points are relative to the detected symbol i.e. topLeft() will return the coordinates of the top-left corner of the symbol. If e.g. the symbol is rotated 180 degrees, the top-left corner will be the one that is at the bottom-right position in the image.
