Result
| Type | Description |
|---|---|
| TGIS_CSProjAbstract | New TGIS_CSProjAbstract instance with identical parameters, datum, ellipsoid, and validity constraints. Caller must free returned object. |
Remarks
PURPOSE:Duplicate projection for use in parallel threads or to preserve original projection while modifying a copy.
BEHAVIOR:Creates new object of same class, copies all parameters (CentralMeridian, ScaleFactor, etc.), datum reference, ellipsoid, and validity extent constraints. Internal state and cached values are reinitialized in the copy.
USAGE:proj2 := proj1.CreateCopy; proj2.CentralMeridian := new_value;
CONSTRAINTS:Returns new instance; caller owns and must free it. Deep copy includes datum/ellipsoid references (shared pointers, not cloned).
