DatasetCoordinateTransformer Class

Members

---

static DatasetCoordinateTransformerPtr create ( ) #

Constructor. Creates a new DatasetCoordinateTransformer class instance with unset systems for transforming.

static DatasetCoordinateTransformerPtr create ( const Ptr<DatasetSpatialReference> & src, const Ptr<DatasetSpatialReference> & dest ) #

Constructor. Creates a new DatasetCoordinateTransformer class instance and sets the src parameter as the source spatial reference system and the dest as the target one.

Arguments

• const Ptr<DatasetSpatialReference> & src - Source spatial reference system.
• const Ptr<DatasetSpatialReference> & dest - Target spatial reference system.

int isValid ( ) #

Returns a value indicating if the valid source and target spatial reference systems are set.

Return value

1 if the valid systems for transforming are set; otherwise, 0.

int setReferences ( const Ptr<DatasetSpatialReference> & src, const Ptr<DatasetSpatialReference> & dest ) #

Sets the src parameter as the source spatial reference system and the dest as the target one. Returns a value indicating if the systems are successfully set and valid.

Arguments

• const Ptr<DatasetSpatialReference> & src - Source spatial reference system.
• const Ptr<DatasetSpatialReference> & dest - Target spatial reference system.

Return value

1 if the systems are successfully set and valid; otherwise, 0.
