-## Usage
+# web font 字体裁剪工具
 
-```bash
-$ npm install # or pnpm install or yarn install
+之前的版本请查看 master 分支，为了能使用 llrt ，我进行了重写，之后只维护此分支
+
+## 起因
+
+ui 需要展现一些特定的字体，但直接引入字体包又过大，于是想到了裁剪字体，一开始想的使用「字蛛」但他是针对静态网站的，而且实际他会多出许多英文的，估计是直接将源码中存在的文字都算进去了。
+后来又找到阿里的「webfont」 但他的字体有限，项目又不开源，所以自己写了这个
+
+## 在线尝试
+
+- [web font 在线站点](https://webfont.shenzilong.cn/)
+
+## 目的与功能
+
+1.裁剪字体包使其仅包含选中的字体
+
+例如 如下图生成的字体包仅包含 「天地无极乾坤借法」
+![界面预览](./doc_img/页面截图.jpg)
+
+<video src="./doc_img/功能演示.mkv" controls="controls" width:100% height:auto></video>
+
+其体积自然十分之小
+
+![体积展示](./doc_img/体积展示.jpg)
+
+2.另外可以生成 css 直接复制可用，部署在公网便可永久访问
+
+例如
+
+```css
+@font-face {
+    font-family: "QIJIC";
+    src: url("http://127.0.0.1:3000/asset/font/1584680576469/令东齐伋复刻体.eot"); /* IE9 */
+    src: url("http://127.0.0.1:3000/asset/font/1584680576469/令东齐伋复刻体.eot?#iefix") format("embedded-opentype"), /* IE6-IE8 */
+    url("http://127.0.0.1:3000/asset/font/1584680576469/令东齐伋复刻体.woff") format("woff"), /* chrome, firefox */
+    url("http://127.0.0.1:3000/asset/font/1584680576469/令东齐伋复刻体.ttf") format("truetype"), /* chrome, firefox, opera, Safari, Android, iOS 4.2+ */
+    url("http://127.0.0.1:3000/asset/font/1584680576469/令东齐伋复刻体.svg#QIJIC") format("svg"); /* iOS 4.1- */
+    font-style: normal;
+    font-weight: normal;
+}
 ```

+3.将 ttf 的字体包放置在 ./asset/font_src/ 目录下自然可以检测到新的可用字体，无需重启服务
 
-## Available Scripts
+![路径预览](./doc_img/路径展示.jpg)
 
-In the project directory, you can run:
+4.提供 zip 的整体下载方案
 
-### `npm run dev`
+![下载展示](./doc_img/下载展示.jpg)
 
-Runs the app in the development mode.<br>
-Open [http://localhost:5173](http://localhost:5173) to view it in the browser.
+## 安装与使用
 
-### `npm run build`
+### 使用docker安装
 
-Builds the app for production to the `dist` folder.<br>
-It correctly bundles Solid in production mode and optimizes the build for the best performance.
+https://hub.docker.com/repository/docker/llej0/web-font
+很小的包体积
+![alt text](doc/image.png)
 
-The build is minified and the filenames include the hashes.<br>
-Your app is ready to be deployed!
+docker compoose.yml
+```yml
+version: 'latest'
+services:
+  app:
+    image: llej0/web-font:latest
+    ports:
+      - "8087:8087"
+    volumes:
+      - /home/zixu/code/webfont/font:/home/font
+```
+其中font目录替换成你的字体文件存放目录
 
-## Deployment
 
-Learn more about deploying your application with the [documentations](https://vitejs.dev/guide/static-deploy.html)
+### 使用node等运行时
+
+pnpm install && pnpm build && pnpm build_backend && node ./dist_backend/
