Matplotlib.artist.artist.get_clip_box()

使用matplotlib库的artist模块中的get_clip_box()方法来获取剪贴框。

语法:

Artist.get_clip_box(self)

参数:该方法不接受任何参数。

返回:该方法返回动画状态。

下面的例子演示了matplotlib中的matplotlib.artist.artist.get_clip_box()函数:

示例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:
