Calculates the buffer of a geometry.
The free function return_buffer 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 return_ prefix returns the buffer, and a template parameter must therefore be specified in the call..
template<typename Output, typename Input, typename T, > Output return_buffer(Input const & geometry, T const & distance, T const & chord_length = -1)
