class QgsQuadrilateral
{
%Docstring
Quadrilateral geometry type.
A quadrilateral is a polygon with four edges (or sides) and four vertices or corners.
This class allows the creation of simple quadrilateral (which does not self-intersect).

%Docstring
Construct a QgsQuadrilateral as a Rectangle from 3 points.
In the case where one of the points is of type PointZ. The other points
will also be of type Z, even if they are of type Point. In addition,
the z used will be the one of the first point with a Z.
This ensures consistency in point types and the ability to export to a
Polygon or LineString.

    static QgsQuadrilateral rectangleFromExtent( const QgsPoint &p1, const QgsPoint &p2 );
%Docstring
Construct a QgsQuadrilateral as a rectangle from an extent, defined by
two opposite corner points.
Z is taken from point ``p1``.

:param p1: first point
:param p2: second point

:param p2: second point
%End

    static QgsQuadrilateral rectangleFromCenterPoint( const QgsPoint &center, const QgsPoint &point );
%Docstring
Construct a QgsQuadrilateral as a rectangle from center point ``center``
and another point ``point``.
Z is taken from ``center`` point.

:param center: center point
:param point: corner point

Compares two QgsQuadrilateral, allowing specification of the maximum allowable difference between points.

%Docstring
Convenient method to determine if a QgsQuadrilateral is valid.
A QgsQuadrilateral must be simple (not self-intersecting) and
cannot have collinear points.

%Docstring
Sets the point ``newPoint`` at the ``index``.
Returns ``False`` if the QgsQuadrilateral is not valid.

    bool setPoints( const QgsPoint &p1, const QgsPoint &p2, const QgsPoint &p3, const QgsPoint &p4 );
%Docstring
Set all points
Returns ``False`` if the QgsQuadrilateral is not valid:
- The points do not have the same type
- The quadrilateral would have auto intersections
- The quadrilateral has double points
- The quadrilateral has collinear points
%End

    QgsPointSequence points() const;
%Docstring
Returns a list including the vertices of the quadrilateral.

    QgsPolygon *toPolygon( bool force2D = false ) const /Factory/;
%Docstring
Returns the quadrilateral as a new polygon. Ownership is transferred to the caller.

%Docstring
Returns the quadrilateral as a new linestring. Ownership is transferred to the caller.

    QString toString( int pointPrecision = 17 ) const;
%Docstring
Returns a string representation of the quadrilateral.
Members will be truncated to the specified precision.
%End

    double area() const;
%Docstring
Returns the area of the quadrilateral, or 0 if the quadrilateral is empty.
