itchat库初探--微信好友全头像的拼接

微信好友全头像

话不多说，直接上代码

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('文件夹' + "/" + str(num) + ".jpg",'wb')

    fileImage.write(img)

    fileImage.close()

    num += 1



ls = os.listdir('文件夹')

each_size = int(math.sqrt(float(640*640)/len(ls)))

lines = int(640/each_size)

image = Image.new('RGBA', (640, 640))

x = 0

y = 0

for i in range(0,len(ls)+1):

    try:

        img = Image.open('文件夹' + "/" + 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('文件夹' + "/" + "all.jpg")

itchat.send_image('文件夹' + "/" + "all.jpg", 'filehelper')

代码运行需要安装两个库

pip install itchat

pip install pillow

如果安装python的时候pip安装选项没打√ ，就先安装pip。
