前情提要
【纯小白，勿喷】刚刚发错区了，重发
由于工作需要，在word中插入大量的手写签名，开始我在网上找在线的网站一个一个转换，但是这样非常麻烦，后来想干脆自己设计一个，现在ai这么强大，你只管提需求，剩下的交ai。
于是我基于自己的需求，通过ai写了一个程序，基于python开发的，我自己一句代码都没写，也不会写，完全是一个小白。有用的上的源码拿走直接用，不保证兼容系统，我自己的windows11正常运行。（当然，手写字体自行下载放入对应的文件夹内）
目录结构如下
/SignatureGenerator
│── /fonts # 存放手写体.ttf文件（用户自备）
│── /output # 生成的签名图片
│── app.py # 主程序（PyQt5界面+核心逻辑）
│── config.py # 配置文件（调整DPI/旋转角度等）
│── requirements.txt # 依赖库清单
