Function Documentation

◆ OGRCreateCoordinateTransformation()

OGRCoordinateTransformation* OGRCreateCoordinateTransformation ( OGRSpatialReference poSource,
OGRSpatialReference poTarget 
)

Create transformation object.

This is the same as the C function OCTNewCoordinateTransformation().

Input spatial reference system objects are assigned by copy (calling clone() method) and no ownership transfer occurs.

The delete operator, or OCTDestroyCoordinateTransformation() should be used to destroy transformation objects.

The PROJ.4 library must be available at run-time.

Parameters
poSourcesource spatial reference system.
poTargettarget spatial reference system.
Returns
NULL on failure or a ready to use transformation object.
