geocircle circle(coordinate center, real radius) const |
Constructs a geocircle centered at center with a radius of radius meters.
coordinate coordinate(real latitude, real longitue, real altitude) const |
Constructs a coordinate with the specified latitude, longitude and optional altitude. Both latitude and longitude must be valid, otherwise an invalid coordinate is returned.
参见 coordinate.
geopath path() const |
georectangle rectangle(coordinate topLeft, coordinate bottomRight) const |
Constructs a georectangle with its top left corner positioned at topLeft and its bottom right corner positioned at bottomLeft.
参见 georectangle.
georectangle rectangle(coordinate center, real width, real height) const |
Constructs a georectangle centered at center with a width of width degrees and a hight of height degrees.
参见 georectangle.
georectangle rectangle() const |
Constructs an invalid georectangle.
参见 georectangle.
georectangle shapeToRectangle(geoshape shape) const |
