All Known Implementing Classes:

Mercator

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface IScaleFactorProvider
```
A Proj implements this interface, if it derives the scale factor value from it's other input parameters. (Normally the scale factor is projection input parameter and the Proj class does not deal with it.)

Since:
