拼接多张图片到一张图

背景

希望能将多张宽高大小不一致的图片，按每组n个合并成一张图片

Show me the code

import os
from PIL import Image

def mergeImages(oriPath,v1Path,v2Path):
    imagefile = []
    oriImg = None
    v1Img = None
    v2Img = None
    try:
        oriImg = Image.open(oriPath).convert('RGB')
        v1Img = Image.open(v1Path).convert('RGB')
        v2Img = Image.open(v2Path).convert('RGB')
    except Exception as e:
        return
    
    imagefile.append(oriImg)
    imagefile.append(v1Img)
    imagefile.append(v2Img)

    width = oriImg.size[0] + v1Img.size[0] + v2Img.size[0]
    height = max(oriImg.size[1],v1Img.size[1],v2Img.size[1])
    target = Image.new('RGB', (width, height))    
    left = 0

    for image in imagefile:
        target.paste(image, (left, 0, left + image.size[0], 0 + image.size[1]))
        left += image.size[0]
        target.save(oriPath.replace("V1","out"), quality = 1000)

def main():

    for root,dirs,files in os.walk("/Users/xx/xx"): 
        for file in files:
            if not "_out" in file:
                oriPath = os.path.join(root,file)
                v1Path = oriPath.replace(".jpg","_out.jpg")
                v2Path = v1Path.replace("V1","V2")
                mergeImages(oriPath,v1Path,v2Path)


if __name__ == '__main__':
    main()
