+# ComfyUI-UniversalToolkit
+
+## 简介
+本插件为 ComfyUI 提供多尺寸空白单元（image/mask/latent）生成节点，结构完全遵循 ComfyUI 插件标准。
+
+## 目录结构
+```
+ComfyUI-UniversalToolkit/
+├── main.py
+├── image_utils.py
+├── requirements.txt
+├── README.md
+└── nodes/
+    ├── __init__.py
+    └── image_nodes.py
+```
+
+## 安装方法
+1. 将本目录放入 ComfyUI 的 custom_nodes 目录下。
+2. 安装依赖：
+   ```bash
+   pip install -r requirements.txt
+   ```
+3. 重启 ComfyUI。
+
+## 节点说明
+### 空单元生成器（EmptyUnitGenerator）
+- 输入参数：
+  - 图像大小：small/medium/large
+  - 构图比例：1:1/3:4/16:9
+  - 颜色：white/black/gray/red/green/blue
+- 输出：
+  - image：空白图像
+  - mask：空白蒙版
+  - latent：空白潜空间
+
+## 依赖
+- Pillow
+- numpy
+
+## 功能特点
+- 模块化设计，各功能独立封装
+- 支持多种基础数据类型处理
+- 提供直观的节点界面
+- 完善的错误处理和参数验证
+
+## 已实现功能
+- 多尺寸、多比例空白图像/mask/latent 一键生成
+  - 支持 small（sd1.5）、medium（flux/sdxl）、large（high resolution）三种尺寸
+  - 支持 1:1、3:4、16:9 等常见比例
+  - 支持自定义颜色
+
+## 使用方法
+1. 启动 ComfyUI
+2. 在节点菜单中找到 "UniversalToolkit" 分类
+3. 选择需要的节点并配置参数
+4. 连接节点并运行工作流
+
+## 开发计划
+- [ ] 添加更多图像处理节点
+- [ ] 添加数据类型转换节点
+- [ ] 添加逻辑处理节点
+- [ ] 优化节点界面
+- [ ] 添加更多示例工作流
