Description copied from interface: ILayer

Transforms the column position relative to the given underlying layer to this layer coordinates.

Specified by:

underlyingToLocalColumnPosition in interface ILayer

Overrides:

underlyingToLocalColumnPosition in class AbstractIndexLayerTransform

Parameters:
