Python 使用PIL numpy 实现拼接图片

def mergeReport(files):

 from PIL import Image

 import numpy as np

 baseimg=Image.open(files[0])

 sz = baseimg.size

 basemat=np.atleast_2d(baseimg)

 for file in files[1:]:

  im=Image.open(file)

 #resize to same width

  sz2 = im.size

  if sz2!=sz:

   im=im.resize((sz[0],round(sz2[0] / sz[0] * sz2[1])),Image.ANTIALIAS)

  mat=np.atleast_2d(im)

  basemat=np.append(basemat,mat,axis=0)

 report_img=Image.fromarray(basemat)

 report_img.save('merge.png')
