python实现图片横向和纵向拼接

本文实例为大家分享了python实现图片横向和纵向拼接的具体代码，供大家参考，具体内容如下

直接上代码：

# -*- 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：
