Python Matplotlib.axis.Axis.get_transformed_clip_path_and_affine()用法及代碼示例

Matplotlib是Python中的一個庫,它是數字的-NumPy庫的數學擴展。它是Python中令人驚歎的可視化庫,用於數組的2D圖,並用於與更廣泛的SciPy堆棧配合使用。

matplotlib.axis.Axis.get_transformed_clip_path_and_affine()函數

matplotlib庫的axis模塊中的Axis.get_transformed_clip_path_and_affine()函數用於獲取應用了其變換的非仿射部分以及其變換的其餘仿射部分的剪輯路徑。

用法: Axis.get_transformed_clip_path_and_affine(self) 

參數:此方法不接受任何參數。

返回值:此方法返回應用了其變換的非仿射部分和其變換的其餘仿射部分的剪輯路徑。



以下示例說明了matplotlib.axis中的matplotlib.axis.Axis.get_transformed_clip_path_and_affine()函數:

範例1:

使用的圖片:

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('image.PNG') as image_file:   
    image = plt.imread(image_file)   
         
fig, ax = plt.subplots()   
im = ax.imshow(image)   
patch = patches.Rectangle((50, 50), 200, 200,    
                          transform = ax.transData)   
    
# use of get_transformed_clip_path_and_affine() method  
val = Axis.get_transformed_clip_path_and_affine(im)  
ax.set_title("Value Return by get_transformed_clip_path_and_affine():" 
             + str(val))  
  
fig.suptitle("""matplotlib.axis.Axis.get_transformed_clip_path_and_affine() 
function Example\n""", fontweight ="bold")   
    
plt.show()

輸出:

範例2:

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)  
    
# use of get_transformed_clip_path_and_affine() method  
val = Axis.get_transformed_clip_path_and_affine(im)  
print("Value Return by get_transformed_clip_path_and_affine():")  
for i in val:   
    print(i) 
      
fig.suptitle("""matplotlib.axis.Axis.get_transformed_clip_path_and_affine() 
function Example\n""", fontweight ="bold")   
    
plt.show()

輸出:

Value Return by get_transformed_clip_path_and_affine():
Path(array([[ 0.,  1.],
       [ 1.,  0.],
       [ 0., -1.],
       [-1.,  0.],
       [ 0.,  1.]]), None)
Affine2D(
    [[ 82.66666667   0.         328.        ]
     [  0.          61.6        237.6       ]
     [  0.           0.           1.        ]])
