# !/usr/bin/env python3

import sys

import imageio  # pip install imageio
import numpy as np

from fluxclient.sdk.delta import Delta


def main():
    frames = 180
    filename = "my_gif.gif"
    images = []

    # set blocking flag to true, this will return move() until it actually finish
    delta = Delta.connect_delta(ip='192.168.18.114', client_key='./sdk_connection.pem', kick=True, blocking=True)
    # move a bit to lock the motor
    delta.move(E2=0, speed=2400)

    for i in range(frames):
        delta.move(E2=360 / frames, relative=True)  # note that we use relative moving here
        img = delta.get_image()  # retrieve the image from delta
        images.append(img)

    delta.close()

    # store the gif
    images_to_gif(filename, images)


def images_to_gif(filename, images):
    imageio.mimsave(filename, [np.array(img) for img in images])
