std::string toGeoJSON(uint32_t precision = 8) const

Convert this box to a GeoJSON text string.

Return
String format of this box.
Parameters
  • precision: Precision for output [default: 8]

void parse(const std::string &s, std::string::size_type &pos)

Parse a string as a BOX2D.

Parameters
  • s: String representation of the box.
  • pos: Position in the string at which to start parsing. On return set to parsing end position.
