How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

markdown-to-image Skill
将 Markdown 文章渲染为小红书风格卡片图片(270×360px,3:4 比例,默认 4× 高清输出)。
快速开始
以下所有命令均假设你已
cd进入 skill 自身目录。 把这个 skill 放在任意位置都可以——脚本通过相对路径调用,不依赖具体安装路径。
第一次使用:安装环境
cd <SKILL_DIR> # 进入 skill 所在目录
python3 -m venv .venv # 创建虚拟环境
.venv/bin/pip install playwright # 安装依赖
.venv/bin/playwright install chromium # 下载 Chromium(约 150MB,仅需一次)或一键运行:
cd <SKILL_DIR>
python3 setup.py生成卡片图片
在 skill 目录下运行:
# 默认 light 主题 + sans 字体
.venv/bin/python scripts/render.py /path/to/article.md
# 指定主题
.venv/bin/python scripts/render.py /path/to/article.md --theme dark
# 指定字体
.venv/bin/python scripts/render.py /path/to/article.md --font serif
# 指定缩放
.venv/bin/python scripts/render.py /path/to/article.md --scale 6PNG 输出到 .md 文件所在目录,命名:<文件名>_01_<主题>_<字体>.png、<文件名>_02_<主题>_<字体>.png...
可选:注册全局命令 —— 把 skill 路径写入 shell alias,避免每次输入完整路径:
# 加到 ~/.zshrc 或 ~/.bashrc alias md2img='<SKILL_DIR>/.venv/bin/python <SKILL_DIR>/scripts/render.py'之后任意位置可直接
md2img article.md --theme warm。
主题(--theme)
| 主题 | 描述 |
light | 白底黑字,蓝色高亮(默认) |
dark | 深蓝底色,浅蓝高亮 |
warm | 暖米底色,橙红高亮 |
forest | 白底黑字,绿色高亮 |
自定义主色调:修改 scripts/render.py 顶部 THEMES 字典中对应主题的 hl 字段。
字体(--font)
| 字体 | 描述 |
sans | 苹方 / 微软雅黑等无衬线(默认) |
serif | 思源宋体 / 宋体等衬线字体 |
添加新字体:在 scripts/render.py 顶部 FONTS 字典新增一条,配置 stack、字号、字重。
缩放倍率(--scale)
| 参数 | 输出像素 | 说明 |
--scale 8 | 2160×2880px | 默认,高清,内嵌图片清晰 |
--scale 4 | 1080×1440px | 文件体积小 |
--scale 2 | 540×720px | 体积最小、加载快 |
--scale 6 | 1620×2160px | 中等高清 |
支持的 Markdown 语法
| 语法 | 渲染效果 |
# h1 / ## h2 / ### h3 | 三级标题 |
| 正文段落 | 8px,行高 1.55 |
**文字** | 主色调高亮(不加粗字重) |
*文字* | 斜体 |
`code` | 内联代码块 |
```...``` | 代码块,字号自动缩放 |
> 引用 | 左侧主色竖线 |
--- | 分割线(不触发分页) |
- item / 1. item | 无序 / 有序列表 |
 | 图片(封面图自动识别) |
![[file.png]] | Obsidian wikilink 图片 |
| 标准 Markdown 表格 | 字号自动缩放适应列数 |
分页逻辑
封面页:# 标题 + 第一张图片(限高由 COVER_IMG_MAX_H 控制,默认 150px,等比缩放保持比例)+ 贪心填充正文段落。
正文页:用 Playwright 真实渲染测量每个节点的 offsetHeight,按实际高度分页。
段落跨页切分:当一段正文塞不下时,自动按字符二分查找能填满剩余空间的最大长度,优先在中文标点(。!?;,:、)处切分。前半段留在当前页,后半段进入下一页。内容不丢失,最后一行完整显示,不会出现半行截断。
--- 渲染为视觉分割线,不触发分页。

└── render.py 核心渲染脚本(Markdown 解析 + Playwright 截图)常见问题
中文字体显示异常? Chromium 使用系统字体。macOS 自带苹方,Windows 自带微软雅黑,Linux 需手动安装:
sudo apt install fonts-noto-cjk网络图片加载失败?
脚本使用 wait_for_load_state("networkidle") 等待图片加载。若图片需要认证或跨域限制,建议换用公开 CDN URL。
如何添加新主题?
在 scripts/render.py 顶部 THEMES 字典中新增一条,包含 bg、text、hl、codeBg、codeText、icBg、icText 七个字段即可。
封面正文太少 / 想多放几段?
封面图默认限高 150px。修改 scripts/render.py 顶部 COVER_IMG_MAX_H 常量(减小数值留更多正文空间,增大数值让图片更显眼)。
Does it work?

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
