Splashes the frame of clip corresponding to time ``t``.
Parameters
----------
t : float or tuple or str, optional
Time in seconds of the frame to display.
with_mask : bool, optional
``False`` if the clip has a mask but you want to see the clip without
the mask.
interactive : bool, optional
Displays the image freezed and you can clip in each pixel to see the
pixel number and its color.
Examples
--------
