g'8dZddlZGddZGddZy)z:Classes for easy interpolation of trajectories and curves.NceZdZdZddZdZy) InterpolatoraYPoorman's linear interpolator. Parameters ---------- tt : list, optional List of time frames for the interpolator. ss : list, optional List of values for the interpolator. ttss : list, optional Lists of time frames and their correspondients values for the interpolator. This argument can be used instead of ``tt`` and ``ss`` to instantiate the interpolator using an unique argument. left : float, optional Value to return when ``t < tt[0]``. right : float, optional Value to return when ``t > tt[-1]``. Examples -------- .. code:: python # instantiate using `tt` and `ss` interpolator = Interpolator(tt=[0, 1, 2], ss=[3, 4, 5]) # instantiate using `ttss` interpolator = Interpolator(ttss=[[0, 3], [1, 4], [2, 5]]) # [t, value] Nc| t|\}}dtj|z|_dtj|z|_||_||_t|t|c|_ |_ yN?) zipnparrayttssleftrightminmaxtmintmax)selfr r ttssr rs j/var/www/it7/html/youtubeDownloader/venv/lib/python3.12/site-packages/moviepy/video/tools/interpolators.py__init__zInterpolator.__init__*sc  $ZFB $ $  "2wB 49ctj||j|j|j|j S)zInterpolates ``t``.

It's designed as an interpolator, so you can get the position at a given time ``t``. You can instantiate it from a file using the methods ``from_file`` and ``load_list``. Parameters ---------- tt : list or numpy.ndarray Time frames. xx : list or numpy.ndarray X positions in the trajectory. yy : list or numpy.ndarray Y positions in the trajectory.
