A class to represent a 2D point.
QgsPointXY project(double distance, double bearing) const
Returns a new point which corresponds to this point projected by a specified distance in a specified ...
QString toString(int precision=-1) const
Returns a string representation of the point (x, y) with a preset precision.
double sqrDist(double x, double y) const
Returns the squared distance between this point a specified x, y coordinate.
double distance(double x, double y) const
Returns the distance between this point and a specified x, y coordinate.
void setY(double y)
Sets the y value of the point.
QString asWkt() const
Returns the well known text representation for the point (e.g.
double azimuth(const QgsPointXY &other) const
Calculates azimuth between this point and other one (clockwise in degree, starting from north)
double sqrDistToSegment(double x1, double y1, double x2, double y2, QgsPointXY &minDistPoint, double epsilon=DEFAULT_SEGMENT_EPSILON) const
