一、设计签名：
1、输入姓名、选择签名样式
2、模拟签名：爬取网上签名图片
3、存在一个小问题：button按钮用grid方法不合理，图片位置放不好。
二、编程环境：
1、python3+pycharm+windows
2、导入模块：tkinter、PIL、requests、re
三、程序代码：
#!/usr/bin/env python
# -*- coding: utf-8 -*-
#python3 + pycharm
#title = 设计签名

from tkinter import messagebox
from PIL import Image,ImageTk

import re
