Our assessment of zan-html-to-ppt
zan-html-to-ppt scores 71/100 on our quality scale, 1815th of 2,717 Development & Engineering skills we index.
Its SKILL.md is 4.7 KB long, well organised into 14 sections with 5 code examples: a solid amount of guidance for an agent.
It has no GitHub stars yet, so there is no community track record; judge it on its content.
Maintenance, license and trust
- The repository was last updated about 3 months ago. That is recent enough to be usable, but agent tooling moves fast, so check the instructions against your agent's current version.
- Our last check on 2026-09-27 found the source still online.
- No license is declared. By default that means all rights are reserved: you can read it, but reusing or redistributing it is not clearly permitted. Ask the author before building on it commercially.
- Its trust signals score 78/100, with 2 cautions from licensing, adoption, age or documentation. These come from repository metadata, not a code audit — read the skill file before letting an agent act on it.

zan-html-to-ppt
把 guizang-ppt-skill 出来的横向翻页 HTML deck 转成线下能用的 PDF + PPTX。 原理:Playwright 控 Chromium 逐页截图,封装成多页 PDF(pdf-lib)和图片型 PPTX(pptxgenjs)。
这个 Skill 做什么
输入一个 guizang-ppt-skill 风格的 HTML deck(横向翻页、单文件、<section class="slide"> 结构),产出三份离线演示资产:
<out>/deck.pdf—— 多页 PDF,每页 16:9 满版。投影 / Preview / Acrobat 直接全屏播。<out>/deck.pptx—— 每页一张 PNG 满版背景的 PPTX(图片型)。可上传任何 PPT 平台。<out>/frames/slide-NN.png—— 每页原始 PNG,默认 5760×3240(--scale 3)。
工作流
Step 1 · 问清必要信息(动手前必做)
向用户问清:
- deck 位置(三种之一,必填):
- 已经在跑的 http URL,例
http://localhost:8810/deck/ - 本地 HTML 文件路径,例
/path/to/deck/index.html(skill 自动起 server) - 本地目录(默认找
index.html)
- 已经在跑的 http URL,例
- 输出目录(可选,默认
./out,建议建一个新目录避免覆盖旧产物) - 清晰度 / 比例(可选,默认
--scale 3出 5760×3240 超清;文件嫌大可降到--scale 2)
Step 2 · 装依赖
bash <SKILL_ROOT>/scripts/setup.sh
幂等。首次跑会装 npm 依赖 + Chromium(~150MB,1–2 分钟,告诉用户在装别静默等);之后秒过。
Step 3 · 跑主脚本
node <SKILL_ROOT>/scripts/build.mjs <input> --out <output-dir>
参数:
| 参数 | 默认 | 说明 |
|---|---|---|
| <input> | 必填 | URL / 本地 HTML 文件 / 本地目录 |
| --out <dir> | ./out | 输出目录 |
| --width <px> | 1920 | CSS 视口宽(影响布局基准) |
| --height <px> | 1080 | CSS 视口高 |
| --scale <n> | 3 | deviceScaleFactor。3 出片 5760×3240(超清);糊就保持 3,文件嫌大降到 2 |
| --wait <ms> | 2500 | 每页 settle 的上限(不是固定睡这么久)。low-power 下入场动画被关,通常 ~300ms 就截完;只有动画/字体没跑完才会等到这个上限。某页缺内容就调大 |
| --format pdf,pptx | 都出 | 输出格式(逗号分隔) |
成功输出长这样:
🌐 http server :60199 root=/path/to/web
📍 Open: http://localhost:60199/deck/
📐 Viewport 1920×1080 · scale=3× (出片 5760×3240) · wait=2500ms · out=/path/to/out
🎞 8 slides
✓ 1/8
✓ 2/8
...
📄 deck.pdf
📊 deck.pptx
✅ Done → /path/to/out/
Step 4 · 报告产物
告诉用户:
<out>/deck.pdf路径<out>/deck.pptx路径- 总页数(脚本输出里有
🎞 N slides) - 调试可看
<out>/frames/slide-NN.png
调用范例
用户:
把我这个 deck 转成 PPT ——
/Users/X/web/deck/index.html,输出到~/Downloads/2026q4-pitch/
你(Agent):
# 1. 首次装依赖(之后秒过)
bash <SKILL_ROOT>/scripts/setup.sh
# 2. 跑
node <SKILL_ROOT>/scripts/build.mjs /Users/X/web/deck/index.html --out ~/Downloads/2026q4-pitch/
看到脚本输出 🎞 8 slides … ✅ Done,然后回报用户:
转好了 ✅ —— 8 页全部捕获。
- PDF:
~/Downloads/2026q4-pitch/deck.pdf(投影 / Preview 直接全屏播)- PPTX:
~/Downloads/2026q4-pitch/deck.pptx(上传任何 PPT 平台)- 调试单页 PNG 在
~/Downloads/2026q4-pitch/frames/
用户嫌文件大(PPTX > 10M)→ 加 --scale 2 重跑,文件降一半。
用户说某页内容空(文字 / 卡片没出来)→ 加 --wait 4000,让入场动画跑完再截。
关键技术细节(理解脚本行为)
- 本地路径如何变 URL:
build.mjs检测 HTML 里的<base href="/X/">,从 fileDir 向上走 X 一级当服务根(例<base href="/deck/">→ 服务 deck 父级,URL =/deck/)。这样图片路径才解析得对。 - 静态模式:打开 deck 后按
B(guizang 内建快捷键)关动效,WebGL 背景仍保留一帧。 - 逐页跳转:
document.querySelectorAll('#nav .dot')[i].click()—— 用 deck 自身的导航点,不模拟键盘(键盘事件容易被 SPA 吃掉)。 - 截图前等待(动画感知):翻页后先给 150ms 让过渡注册,再轮询
document.getAnimations()到没有 running 动画才截,封顶--wait。low-power 下入场动画被关 → 几乎立刻返回(每页 ~300ms,不再死等 2.5s);只有动画/字体真没跑完才会等到上限。 - fonts.ready:打开页面后等
document.fonts.ready+networkidle+ 1.5s 给 WebGL 暖机,字体才渲染对。 - deviceScaleFactor:默认 3(Retina 级),是治糊的关键。1× 在 Retina/投影/PowerPoint 渲染都会显得软。
- 单页失败不致命:每页截图独立 try/catch,某页报错(超时 / DOM 异常 / 写盘失败)只记下页码继续,末尾汇总
⚠️ N/M 失败:[...],已成功的页照常拼进 PDF/PPTX;全失败才退出。 - PPTX 长宽比跟视口走:PPTX 版面由
--width/--height比例推导(高 7.5in × W/H),16:9 仍是 13.333×7.5,但 4:3 / 方形 / 竖版 deck 也不会被拉变形。
故障排查
| 现象 | 原因 | 改 |
|---|---|---|
| 帧内容缺 / 一片空白 | stagger 没跑完 | --wait 4000 或更大 |
| 字体没渲染对 | Google Fonts 没下完 | --wait 4000 + 确认有网 |
| 某页排版漂 | 视口和 deck 设计基准不一致 | --width 1920 --height 1080(guizang 设计基准) |
| 本地 HTML 图片 404 | <base href> 路径错 | 给 skill 整个目录,不要单文件 |
| Chromium 启不来 | 没装 | 重跑 bash scripts/setup.sh |
| 帧还是糊 | scale 太小 | --scale 4(文件会更大) |
| 文件太大 | scale 过大 | --scale 2(出片 3840×2160,体积降一半) |

<section class="slide">是页面容器#nav .dot[i]是页码导航点(用于跳转)- 键盘
B切静态模式 document.fonts.readyWeb Fonts API
