python如何实现图片横向和纵向拼接 python实现图片横向和纵向拼接代码

本篇文章小编给大家分享一下python实现图片横向和纵向拼接代码，小编觉得挺不错的，现在分享给大家供大家参考，有需要的小伙伴们可以来看看。

代码如下：

# -*- coding:utf-8 -*-
__author__ = 'ShawDa'

from PIL import Image

def join(png1, png2, flag='horizontal'):
  """
  :param png1: path
  :param png2: path
  :param flag: horizontal or vertical
  :return:
  """
  img1, img2 = Image.open(png1), Image.open(png2)
  size1, size2 = img1.size, img2.size
  if flag == 'horizontal':
    joint = Image.new('RGB', (size1[0]+size2[0], size1[1]))
    loc1, loc2 = (0, 0), (size1[0], 0)
    joint.paste(img1, loc1)
    joint.paste(img2, loc2)
    joint.save('horizontal.png')
  elif flag == 'vertical':
    joint = Image.new('RGB', (size1[0], size1[1]+size2[1]))
    loc1, loc2 = (0, 0), (0, size1[1])
    joint.paste(img1, loc1)
    joint.paste(img2, loc2)
    joint.save('vertical.png')


if __name__ == '__main__':
  png = 'lena.png'
  join(png, png)
  join(png, png, flag='vertical')

结果：
