用python + pillow实现GUI界面图片GUI处理工具

用python pillow实现GUI界面图片GUI处理工具该工具采用Tkinter构建GUI界面功能调整图片大小转换图片格式保存图片裁剪、旋转、翻转亮度 / 对比度 / 饱和度调整滤镜效果模糊、锐化、黑白等等运行截图安装依赖第三方库pip install pillowPython第三方模块(库、包)安装、卸载与查看及常见问题解决可参见 https://blog.csdn.net/cnds123/article/details/104393385Pillow 上手简单适合绝大多数日常图像处理场景比如裁剪、调色、加滤镜它是经典的 PILPython Imaging Library的活跃分支也是 PIL 停止维护后的官方替代方案。需要注意的是安装时新手要特别注意需要执行 pip install pillow 命令但在代码中导入库时必须使用 import PIL而非 import pillow—— 这是因为 Pillow 完全兼容 PIL 的 API 命名体系保留了“PIL”这个导入标识仅在包安装层面使用“pillow”名称。pillow库PIL库的使用https://blog.csdn.net/cnds123/article/details/126141838官网 https://pillow.readthedocs.io/en/stable/中文参靠 https://pillow-docs-cn.readthedocs.io/zh-cn/latest/ 或 https://osgeo.cn/pillow/reference/index.html源码如下import tkinter as tk from tkinter import filedialog, messagebox, ttk from PIL import Image, ImageTk, ImageEnhance, ImageFilter #
