Python Matplotlib.axes.Axes.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。軸類包含大多數圖形元素:Axis,Tick,Line2D,Text,Polygon等,並設置坐標係。 Axes實例通過callbacks屬性支持回調。

matplotlib.axes.Axes.get_transformed_clip_path_and_affine()函數

matplotlib庫的axiss模塊中的Axes.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: Axes.get_transformed_clip_path_and_affine(self)


參數:此方法不接受任何參數。

返回: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.axes中的matplotlib.axes.Axes.get_transformed_clip_path_and_affine()函數:

# Implementation of matplotlib function 
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((0, 0), 260, 200,  
                          transform = ax.transData) 
   
ax.set_title("Value Return by get_transformed_clip_path_and_affine():"
             +str(im.get_transformed_clip_path_and_affine())) 
       
fig.suptitle('matplotlib.axes.Axes.get_transformed_clip_path_and_affine()\ 
 function Example\n\n', fontweight ="bold") 
  
plt.show()

輸出:

範例2:

# Implementation of matplotlib function 
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) 
  
print("Value Return by get_transformed_clip_path_and_affine():") 
  
for i in im.get_transformed_clip_path_and_affine():
    print(i) 
       
fig.suptitle('matplotlib.axes.Axes.get_transformed_clip_path_and_affine()\ 
 function Example\n\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)

     [  0.          61.6        237.6       ]
     [  0.           0.           1.        ]])
