Member RNifti::NiftiImage::isPersistent () const: The persistence mechanism has been replaced with reference counting, so this function will always return false. Use isShared instead.
Member RNifti::NiftiImage::setPersistence (const bool persistent): The persistence mechanism has been replaced with reference counting, so this function no longer has any effect. Instead it returns *this, unmodified.
