今天在朋友圈看到有人发了微信好友拼接图，心里满是新奇，看了下评论才知道用Python写的。心里痒痒，立马就安装了下Python。
安装好了之后，看了下大神的代码，基本上能够读得懂（语言都是想通的嘛！），然后就尝试在小黑窗运行了，结果报错了！
rawmode = RAWMODE[im.mode] KeyError: 'RGBA'
这种错误看的我是一脸懵逼啊，搜索了半天也没看到什么解决方案，结果就在宁外一篇博客的评论里面发现了解决方法，结果成功运行，还是66的。
import itchat
import math
import PIL.Image as Image
import os itchat.auto_login()
friends = itchat.get_friends(update=True)[0:]
user = friends[0]["UserName"] num = 0
for i in friends:
img = itchat.get_head_img(userName=i["UserName"])
fileImage = open('D:' + "/wechat_head_image/" + str(num) + ".jpg",'wb')
fileImage.write(img)
fileImage.close()
num += 1 ls = os.listdir('D:/wechat_head_image')
each_size = int(math.sqrt(float(640*640)/len(ls)))
lines = int(640/each_size)
image = Image.new('RGB', (640, 640))
x = 0
y = 0
for i in range(0,len(ls)+1):
try:
img = Image.open('D:/wechat_head_image' + "/" + str(i) + ".jpg")
except IOError:
print("Error")
else:
img = img.resize((each_size, each_size), Image.ANTIALIAS)
image.paste(img, (x * each_size, y * each_size))
x += 1
if x == lines:
x = 0
y += 1
image.save('D:/wechat_head_image/all' + "/" + "all.jpg")
itchat.send_image('D:/wechat_head_image/all' + "/" + "all.jpg", 'filehelper')
运行后效果截图
