Matplotlib.artist.artist.set_rasterized()
Python matplotlib库的artist模块中的set_rasterized()方法用于在矢量后端输出中强制光栅化(位图)绘图。
语法:Artist.set_rasterized(self,rasterized)
参数:该方法接受以下参数。
- rasterized:该参数是布尔值。
Returns:该方法不返回任何值。
下面的例子说明了matplotlib中的matplotlib.artist.artist.set_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)
Artist.set_rasterized(m, True)
fig.suptitle('matplotlib.artist.Artist.set_rasterized()\
function Example', fontweight ="bold")
plt.show()
输出:
示例2
# 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)
Artist.set_rasterized(im, False)
fig.suptitle('matplotlib.artist.Artist.set_rasterized()\
function Example', fontweight ="bold")
plt.show()
输出:
