Detailed Description

Transform functor that calls Boost.Geometry with the correct parameter types.

The functor throws exceptions and is therefore only intended used to implement transform or other geographic functions. It should not be used directly by other MySQL code.

Constructor & Destructor Documentation

◆ Transform()

gis::Transform::Transform	(	const std::string &	old_srs_params,
		const std::string &	new_srs_params,
		Coordinate_system	output_cs
	)

Create a new transform functor.

Theoretically, we could deduce the coordinate system of the output SRS from the old_srs_param proj4 string, but it's easier to get it from the DD SRS object on the caller side.

Parameters

[in]	old_srs_params	The proj4 parameters of the input SRS.
[in]	new_srs_params	The proj4 parameters of the output SRS.
[in]	output_cs	The coordinate system of the output SRS.
