| OGRSpatialReference * OGRProj4CT::GetSourceCS | ( | ) | [virtual] |
Fetch internal source coordinate system.
Implements OGRCoordinateTransformation.

Fetch internal target coordinate system.
Implements OGRCoordinateTransformation.
| int OGRProj4CT::Transform | ( | int | nCount, |

| ) | [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. |
Implements OGRCoordinateTransformation.
