Unigine.DatasetCoordinateTransformer Class

The DatasetCoordinateTransformer class is intended for transforming between coordinate systems.

DatasetCoordinateTransformer Class

Members

---

DatasetCoordinateTransformer()

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

DatasetCoordinateTransformer(DatasetSpatialReference src, 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

• DatasetSpatialReference src - Source spatial reference system.
• DatasetSpatialReference dest - Target spatial reference system.

DatasetCoordinateTransformer(DatasetCoordinateTransformer other)

Constructor. Creates a new DatasetCoordinateTransformer class instance from another one and takes the source and target spatial reference systems from it.

Arguments

• DatasetCoordinateTransformer other - a DatasetCoordinateTransformer class instance.

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(DatasetSpatialReference src, 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

• DatasetSpatialReference src - Source spatial reference system.
• DatasetSpatialReference dest - Target spatial reference system.

Return value

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