Matplotlib.artist.artist.get_rasterized()

matplotlib库的artist模块中的get_rasterized()方法用于获取艺术家是否需要栅格化。

语法:

Artist.get_rasterized(self)

参数:该方法不接受任何参数。

返回:该方法返回艺术家是否要栅格化。

下面的例子演示了matplotlib中matplotlib.artist.artist.get_rasterized()函数:

示例1

# Implementation of matplotlib function
from matplotlib.artist import Artist  
import numpy as np 
import matplotlib.pyplot as plt 
  
      
d = np.arange(100).reshape(10, 10) 
xx, yy = np.meshgrid(np.arange(11), np.arange(11)) 
      
fig, ax = plt.subplots() 
      
ax.set_aspect(1) 
m = ax.pcolormesh(xx, yy, d) 
  
if Artist.get_rasterized(m)== None: 
    Artist.set_rasterized(m, True)
  
fig.suptitle('matplotlib.artist.Artist.get_rasterized()\
function Example', fontweight ="bold") 
  
plt.show()

输出:

# Implementation of matplotlib function
from matplotlib.artist import Artist  
import matplotlib.pyplot as plt 
import matplotlib.colors as mcolors 
import matplotlib.gridspec as gridspec 
import numpy as np 
      
      
arr = np.arange(100).reshape((10, 10)) 
norm = mcolors.Normalize(vmin = 0., vmax = 100.) 
      
pc_kwargs = {'cmap': 'plasma', 'norm': norm} 
      
fig, ax = plt.subplots( ) 
      
im = ax.pcolormesh(arr, **pc_kwargs) 
fig.colorbar(im, ax = ax, shrink = 0.6)
  
if Artist.get_rasterized(im)== None: 
    Artist.set_rasterized(im, False)
  
fig.suptitle('matplotlib.artist.Artist.get_rasterized()\
function Example', fontweight ="bold") 
plt.show()

输出:
