| virtual OGRSpatialReference* OGRCoordinateTransformation::GetSourceCS | ( | ) | [pure virtual] |
Fetch internal source coordinate system.
| virtual OGRSpatialReference* OGRCoordinateTransformation::GetTargetCS | ( | ) | [pure virtual] |
Fetch internal target coordinate system.

| virtual int OGRCoordinateTransformation::Transform | ( | int | nCount, | |
| double * | x, | |||
| double * | y, | |||
| double * | z = NULL | |||
| ) | [pure virtual] |
Transform points from source to destination space.
This method is the same as the C function OCTTransform().
The method TransformEx() allows extended success information to be captured indicating which points failed to transform.
| nCount | number of points to transform. | |
| x | array of nCount X vertices, modified in place. | |
| y | array of nCount Y vertices, modified in place. | |
| z | array of nCount Z vertices, modified in place. |
