exposures(list of float, optional): f specified, samples for each exposure time value in each xy position.
|
|
settling_time(float, optional): time in seconds to wait after positioners are set, before sampling sensors.

zigzag(boolean, optional): if True each fast changing dimension revert direction after finishing a line.

compression(boolean, optional): if True images are saved compressed.
