[section:buffer buffer]
|
|
|
|
Calculates the buffer of a geometry.
|
|
|
|
[heading Description]
|
|
The free function buffer calculates the buffer (a polygon being the spatial point set collection within a specified maximum distance from a geometry) of a geometry.
|
|
|
|
[heading Synopsis]
|
|
``template<typename Input, typename Output, typename Distance>
|
|
void buffer(Input const & geometry_in, Output & geometry_out, Distance const & distance, Distance const & chord_length = -1)``
|
|
|
|
[heading Parameters]
|
|
|
|
[table
|
|
[[Type] [Concept] [Name] [Description] ]
|
|
[[Input const &] [Any type fulfilling a Geometry Concept ] [geometry_in] [A model of the specified concept ]]
|
|
[[Output &] [Any type fulfilling a Geometry Concept ] [geometry_out] [A model of the specified concept ]]
|
|
[[Distance const &] [numerical type (int, double, ttmath, ...) ] [distance] [The distance to be used for the buffer ]]
|
|
[[Distance const &] [numerical type (int, double, ttmath, ...) ] [chord_length] [(optional) The length of the chord's in the generated arcs around points or bends ]]

[section:make_buffer make_buffer]
|
|
|
|
Calculates the buffer of a geometry.
|
|
|
|
[heading Description]
|
|
The free function make\u005fbuffer calculates the buffer (a polygon being the spatial point set collection within a specified maximum distance from a geometry) of a geometry. This version with the make\u005f prefix returns the buffer, and a template parameter must therefore be specified in the call..
|
|
|
|
[heading Synopsis]
|
|
``template<typename Output, typename Input, typename T, >
|
|
Output make_buffer(Input const & geometry, T const & distance, T const & chord_length = -1)``
|
|
|
|
[heading Parameters]
|

|
[[Type] [Concept] [Name] [Description] ]
|
|
[[Output] [Any type fulfilling a Geometry Concept ] [ - ] [Must be specified]]
|
|
[[Distance] [numerical type (int, double, ttmath, ...) ] [ - ] [Must be specified]]
|
|
[[Input const &] [Any type fulfilling a Geometry Concept ] [geometry] [A model of the specified concept ]]
|
|
[[T const &] [] [distance] [The distance to be used for the buffer ]]
|

[[T const &] [] [chord_length] [(optional) The length of the chord's in the generated arcs around points or bends ]]
