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.

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.
[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. |
