WRAPPER_API bool GetCenterOnMeridianFlag() const
This function allows the user to get how the central meridian of a projection affects the transformation of points. If the CenterOnMeridian flag is true, transformed values will be kept within a range of +/-180 around the central meridian of the projected coordinate system used in the transformation. If the CenterOnMeridian flag is false, transformed values will not be altered.
Please note that presently this range will only be applied when performing transformations to a projected coordinate system. When taking a projected coordinate point and transforming it to a geodetic system, the longitude values will not necessarily be within the +/-180 range around the central meridian of the original projection.
