EQuadrangle Class
This class represents a polygon with four corners (with sub-pixel accuracy).
Remarks
A quadrangle especially arises when representing the corners of a rotated bounding box.
Namespace: Euresys::Open_eVision
Methods
Draws the quadrangle, by drawing lines between its corners.
Draws the quadrangle, by drawing lines between its corners.
Constructs a EQuadrangle. The default constructor initializes all points to 0.
Returns the area of the quadrangle.
Returns the angle of a given corner of the quadrangle.
The corners of the EQuadrangle.
Returns the gravity center of the quadrangle.
Returns the perimeter of the quadrangle.
Returns the coordinate of a given corner of the quadrangle.
Returns the angle of a given side of the quadrangle.
Returns the length of a given side of the quadrangle.
Returns the coordinates of the upper left corner of the quadrangle (the position with the minimum Y and then minimum X).
Tests if a point is inside the quadrangle.
Tests if a quadrangle is inside the quadrangle.
Assignment operator.
Tests if the quadrangles overlap.
Sets the coordinates of a given corner of the quadrangle.
