Python中的 Matplotlib.axis.Axis.get_clip_path()函数

Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。它是Python中用于二维数组图的惊人可视化库,用于处理更广泛的 SciPy 堆栈。

Matplotlib.axis.Axis.get_clip_path()函数

matplotlib库的axis模块中的Axis.get_clip_path()函数用于获取剪辑路径。

下面的示例说明了 matplotlib.axis 中的 matplotlib.axis.Axis.get_clip_path()函数:

示例 1:

使用的图像

Python3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import matplotlib.pyplot as plt  
import matplotlib.patches as patches  
import matplotlib.cbook as cbook  
       
      
with cbook.get_sample_data('loggf.PNG') as image_file:  
    image = plt.imread(image_file)  
       
fig, ax = plt.subplots()  
im = ax.imshow(image)  
patch = patches.Rectangle((10, 10),  
                          560,  
                          500,   
                          transform = ax.transData)   
    
if Axis.get_clip_path(im) is None:  
    im.set_clip_path(patch)
  
fig.suptitle("""matplotlib.axis.Axis.get_clip_path()
function Example\n""", fontweight ="bold")  
    
plt.show()


Python3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np  
import matplotlib.cm as cm  
import matplotlib.pyplot as plt  
from matplotlib.path import Path  
from matplotlib.patches import PathPatch  
       
      
delta = 0.025
      
x = y = np.arange(-3.0, 3.0, delta)  
X, Y = np.meshgrid(x, y)  
      
Z1 = np.exp(-X**2 - Y**2)  
Z2 = np.exp(-(X - 1)**2 - (Y - 1)**2)  
Z = (Z1 - Z2) * 2
       
path = Path([[0, 1], [1, 0], [0, -1],  
            [-1, 0], [0, 1]])  
patch = PathPatch(path, facecolor ='none')  
       
fig, ax = plt.subplots()  
ax.add_patch(patch)  
       
im = ax.imshow(Z,  
               interpolation ='bilinear',   
               cmap = cm.gray,  
               origin ='lower',   
               extent =[-3, 3, -3, 3],  
               clip_path = patch,   
               clip_on = True)  
ax.text(-2.8, 2, str(Axis.get_clip_path(im)))
  
fig.suptitle("""matplotlib.axis.Axis.get_clip_path()
function Example\n""", fontweight ="bold")  
    
plt.show()


输出:
