Python Matplotlib.axes.Axes.get_images()用法及代码示例


Matplotlib是Python中的一个库,它是数字的-NumPy库的数学扩展。轴类包含大多数图形元素:Axis,Tick,Line2D,Text,Polygon等,并设置坐标系。 Axes实例通过callbacks属性支持回调。

matplotlib.axes.Axes.get_images()函数

matplotlib库的axiss模块中的Axes.get_images()函数用于返回由Axes包含的Axes图像列表

用法: Axes.get_images(self)


参数:此方法不接受任何参数。

返回:此方法返回轴包含的轴图像列表。

以下示例说明了matplotlib.axes中的matplotlib.axes.Axes.get_images()函数:

范例1:

# Implementation of matplotlib function 
import matplotlib.pyplot as plt 
import matplotlib.patches as patches 
import matplotlib.cbook as cbook 
   
      
# image used is  
# https://media.geeksforgeeks.org/ 
# wp-content/uploads/20200402214740/geek.jpg 
with cbook.get_sample_data('geek.jpg') as image_file:
    image = plt.imread(image_file) 
  
fig, ax = plt.subplots() 
im = ax.imshow(image) 
  
patch = patches.Rectangle((0, 0), 260, 200, 
                          transform = ax.transData) 
im.set_clip_path(patch) 
  
print("List of the child Artists of this Artist \n", 
      *list(ax.get_images()), sep ="\n") 
  
fig.suptitle('matplotlib.axes.Axes.get_images() \ 
function Example', fontweight ="bold") 
  
plt.show()

输出:

List of the Axes images contained by the Axes

AxesImage(80, 52.8;496x369.6)

范例2:

# Implementation of matplotlib function 
import matplotlib.pyplot as plt 
import numpy as np 
from matplotlib.colors import LogNorm 
      
dx, dy = 0.015, 0.05
x = np.arange(-4.0, 4.0, dx) 
y = np.arange(-4.0, 4.0, dy) 
X, Y = np.meshgrid(x, y) 
   
extent = np.min(x), np.max(x), np.min(y), np.max(y) 
    
fig, ax = plt.subplots() 
   
Z1 = np.add.outer(range(8), range(8)) % 2
ax.imshow(Z1, cmap ="binary_r", 
          interpolation ='nearest', 
          extent = extent, alpha = 1) 
   
def geeks(x, y):
    return (1 - x / 2 + x**5 + y**6) * np.exp(-(x**2 + y**2)) 
   
Z2 = geeks(X, Y) 
   
ax.imshow(Z2, cmap ="Greens", alpha = 0.7, 
          interpolation ='bilinear', 
          extent = extent) 
  
print("List of the Axes images contained by the Axes \n", 
      *list(ax.get_images()), sep ="\n") 
  
fig.suptitle('matplotlib.axes.Axes.get_images() function\ 
 Example', fontweight ="bold") 
plt.show()

输出:

List of the Axes images contained by the Axes 

AxesImage(80, 52.8;496x369.6)
AxesImage(80, 52.8;496x369.6)
