Floating point polyline representation.

A polyline is a continuous line composed of one or more straight line segments. A QVPolylineF is a implementation of a polyline, specified by a list of the points located at the intersection of the segments. Thus, any QVPolylineF object inherits from the class QList<QPointF>. More...

Detailed Description

Floating point polyline representation.

A polyline is a continuous line composed of one or more straight line segments. A QVPolylineF is a implementation of a polyline, specified by a list of the points located at the intersection of the segments. Thus, any QVPolylineF object inherits from the class QList<QPointF>.

When a polyline is closed, then it is considered to be a polygon. In that case it is supposed to have an implicit final straight line segment, that links the first and the last point in the polyline. The property QVPolylineF::closed will store the value TRUE if the polyline is a polygon, else storing FALSE.

A QVPolylineF has the property QVPolylineF::direction, that will indicate if it is a direct polyline, or a reverse polyline. It has only meaning for some algorithms, like getBorderContourThreshold.
