使用预先计算的图像列表的动画图像

使用预先计算的图像列表的动画图像示例

  1. import numpy as np
  2. import matplotlib.pyplot as plt
  3. import matplotlib.animation as animation
  5. fig = plt.figure()
  8. def f(x, y):
  9.     return np.sin(x) + np.cos(y)
  11. x = np.linspace(0, 2 * np.pi, 120)
  12. y = np.linspace(0, 2 * np.pi, 100).reshape(-1, 1)
  13. # ims is a list of lists, each row is a list of artists to draw in the
  14. # current frame; here we are just animating one artist, the image, in
  15. # each frame
  16. ims = []
  17. for i in range(60):
  18.     x += np.pi / 15.
  19.     y += np.pi / 20.
  20.     im = plt.imshow(f(x, y), animated=True)
  21.     ims.append([im])
  23. ani = animation.ArtistAnimation(fig, ims, interval=50, blit=True,
  24.                                 repeat_delay=1000)
  26. # To save the animation, use e.g.
  27. #
  28. # ani.save("movie.mp4")
  29. #
  30. # or
  31. #
  32. # from matplotlib.animation import FFMpegWriter
  33. # writer = FFMpegWriter(fps=15, metadata=dict(artist='Me'), bitrate=1800)
  34. # ani.save("movie.mp4", writer=writer)
  36. plt.show()
