Detailed Description

Function Documentation

template<std::size_t Dimension, typename Geometry >
void boost::geometry::set ( Geometry &  geometry,
typename coordinate_type< Geometry >::type const &  value 
)

Set coordinate value of a geometry (usually a point)

The free functions [*get] and [*set] are two of the most important functions of Boost.Geometry, both within the library, as also for the library user. With these two functions you normally get and set coordinate values from and for a point, box, segment or sphere.

Template Parameters
DimensionDimension, this template parameter is required. Should contain \[0 .. n-1\] for an n-dimensional geometry
GeometryAny type fulfilling a Geometry Concept (usually a Point Concept)
Parameters
geometrygeometry to assign coordinate to
geometryA model of the specified concept (usually a point)
valueThe coordinate value to set
Examples:
c05_custom_point_pointer_example.cpp.
template<std::size_t Index, std::size_t Dimension, typename Geometry >
void boost::geometry::set ( Geometry &  geometry,
typename coordinate_type< Geometry >::type const &  value 
)

set coordinate value of a Box / Segment

The free functions [*get] and [*set] are two of the most important functions of Boost.Geometry, both within the library, as also for the library user. With these two functions you normally get and set coordinate values from and for a point, box, segment or sphere.

Template Parameters
IndexIndex, this template parameter is required. For a Box: either min_corner or max_corner. For a Segment: either 0 or 1 for first or last point.
DimensionDimension, this template parameter is required. Should contain \[0 .. n-1\] for an n-dimensional geometry
GeometryAny type fulfilling a Box Concept or a Segment Concept
Parameters
geometrygeometry to assign coordinate to
geometryA model of the specified concept
valueThe coordinate value to set
template<std::size_t Dimension, typename Geometry >
void boost::geometry::set_from_radian ( Geometry &  geometry,
typename fp_coordinate_type< Geometry >::type const &  radians 
)

set coordinate value (in radian) to a point

Coordinate value will be set correctly, if coordinate system of point is in Degree, Radian value will be converted to Degree

Template Parameters
Dimensiondimension
Geometrygeometry
Parameters
geometrygeometry to assign coordinate to
radianscoordinate value to assign
Note
Only applicable to coordinate systems templatized by units, e.g. spherical or geographic coordinate systems
