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：
