利用python拼接图片

问题描述: 将16张图片拼接成4x4的图片, 且不改变每单张图片的像素值.

代码如下:

 import os
 from PIL import Image
 path = '/share1/home/cong/Datasets/resized_Polyvore/pair1/pair1'
 imglist = os.listdir(path)
 imglist.sort()
 imglist = imglist[:16]
 images = []
 for item in imglist:
     images.append(Image.open(path + '/' + item))

 h, w = 128, 128
 target = Image.new('RGBA', (w * 4, h * 4))
 for idx, img in enumerate(images):
     i = idx % 4
     j = idx // 4
     target.paste(img, (i * w, j * h, i * w + w, j * h + h))

 target.save('.' + '/' + 'real.png')

效果如下:
