pythonplt如何保存图片 python中如何保存图片

分享使用 python 进行图像处理时，几种常见的图片读取和存储的方式。

Imagefrom PIL import Image
img = Image.open('img.jpg')
print(type(img)) # 
print(img) # 
img.show()
img.save('img_copy.jpg')
import numpy as np
img = np.array(img)
print(type(img)) # 
print(img.shape) # (531, 742, 3)
skimagefrom skimage import io
img=io.imread('img.jpg')
print(type(img)) # 
print(img.shape) # (531, 742, 3)
io.imshow(img)
io.show()
io.imsave('img_copy.jpg', img)
matplotlibimport matplotlib.pyplot as plt
img = plt.imread('img.jpg')
print(type(img)) # 
print(img.shape) # (531, 742, 3)
plt.imshow(img)
plt.show()
plt.imsave('img_copy.jpg', img)
cv2import cv2
img = cv2.imread('img.jpg')
print(type(img)) # 
print(img.shape) # (531, 742, 3)
cv2.imshow('image',img)
cv2.waitKey(0)
cv2.imwrite('img_copy.jpg', img)
scipyimport scipy.misc
img = scipy.misc.imread('img.jpg')
print(type(img)) # 
print(img.shape) # (531, 742, 3)
from os import environ
environ['SCIPY_PIL_IMAGE_VIEWER'] = '' # 这里填 image viewer 路径
scipy.misc.imshow(img)
scipy.misc.imsave('img_copy.jpg', img)
