numpy.transpose

import numpy as np 
from PIL import Image


img = Image.open('snorlax.jpeg')
img.show()

snorlax.jpeg

convert_img = Image.fromarray(convert)
convert_img.show()
# convert_img.save('snorlax_transpose.jpeg'')

snorlax_transpose.jpeg

即,将图像向左旋转90°

• Origin

  data = np.asarray(img, dtype='uint8') 
  print(data.shape)  # Outputs: (959, 959, 3)
  

• convert

    convert = data.transpose(1,0,2)  # 交换第一维\第二维数据
    print(convert.shape)  # Outputs: (959, 959, 3)
  

• convert_1

  convert_1 = data.transpose(2,0,1)
  print(convert_1.shape)  # Outputs: (3, 959, 959)
