ShiftMap
ShiftMap(offset=0.0, source_unit=None, target_unit=None, uid=None, name=None)Pure offset transformation: y = x + offset.
A simplified version of LinearMap with scalar=1.
Examples: >>> # Add an offset to timestamps >>> shift = ShiftMap(offset=10.0) >>> shift(5.0) 15.0
>>> # Can be used to align timelines with different origins
>>> align = ShiftMap(offset=-100) # Subtract 100 from all coordinates
>>> align(150)
