背景
最近有一些图片需要增加水印，找了一圈也没看见比较好的工具，又不想用破解的PS，干脆自己做了一个GUI工具，有需要的同学自取
功能
- 支持水印预览
- 自定义水印文字内容
- 支持行楷和微软雅黑两种字体
- 支持自定义字号
- 支持自定义水印颜色
- 支持自定义水印间距
- 支持自定义水印透明度
- 支持自定义水印旋转角度
- 支持批量给图片增加水印
- 仅支持Windows平台（用到了windows上的字体）
预览
使用方式
方法一：运行Python脚本。
电脑上需要安装python3运行环境
# 安装依赖包
pip install pillow pysimplegui
# 将下面的源码保存为: image_watermark_tool.py
python image_watermark_tool.py
方法二：直接下载exe文件，双击运行即可。
