Matplotlib是Python中的一个库，它是数字的-NumPy库的数学扩展。 Artist类包含用于呈现到FigureCanvas中的对象的Abstract基类。图中所有可见元素都是Artist的子类。
matplotlib.artist.Artist.get_clip_box()方法
matplotlib库的artist模块中的get_clip_box()方法用于获取剪贴板。
用法：Artist.get_clip_box(self)
参数：此方法不接受任何参数。
返回：此方法返回动画状态。
以下示例说明了matplotlib中的matplotlib.artist.Artist.get_clip_box()函数：
范例1：
# Implementation of matplotlib function
from matplotlib.artist import Artist
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.patches import Ellipse
delta = 45.0
angles = np.arange(0, 360 + delta, delta)
ells = [Ellipse((2, 2), 5, 2, a) for a in angles]
fig, ax = plt.subplots()
print("Value Return by get_clip_box()")
for e in ells:
Artist.set_clip_box(e, ax.bbox)
print(Artist.get_clip_box(e))
e.set_alpha(0.1)
ax.add_artist(e)
plt.xlim(-1, 5)
plt.ylim(-1, 5)
fig.suptitle('matplotlib.artist.Artist.get_clip_box() \
function Example', fontweight ="bold")
plt.show()输出：
