* export_deck_pptx.mjs — 把多文件 slide deck 导出为 PPTX(图片铺底)
|
||||
* export_deck_pptx.mjs — 把多文件 slide deck 导出为 PPTX
|
||||
*
|
||||
* 两种模式:
|
||||
* --mode image 图片铺底,视觉 100% 保真,⚠️ 文字不可编辑
|
||||
* --mode editable 文本框原生,文字可编辑,要求 HTML 符合 4 条硬约束(见 references/editable-pptx.md)
|
||||
*
|
||||
* 用法:
|
||||
* node export_deck_pptx.mjs --slides <dir> --out <file.pptx> [--width 1920] [--height 1080]
|
||||
* # 图片模式(默认)
|
||||
* node export_deck_pptx.mjs --slides <dir> --out <file.pptx>
|
||||
* # 可编辑模式
|
||||
* node export_deck_pptx.mjs --slides <dir> --out <file.pptx> --mode editable
|
||||
*
|
||||
* 特点:
|
||||
* --mode image 特点:
|
||||
* - 每张 slide 截图成 PNG,满铺一张 PPTX 页面
|
||||
* - 视觉 100% 保真(因为就是图片)
|
||||
* - ⚠️ 文字不可编辑(文字变成了图片)
|
||||
* - 文字不可编辑
|
||||
* - HTML 随便写,不挑格式
|
||||
*
|
||||
* 如果用户需要「可编辑文字」的 PPTX:
|
||||
* ❌ 不要在 claude-design 的 HTML 上硬上 html2pptx——claude-design 的 HTML 视觉自由度高,
|
||||
* 很少能满足 html2pptx 的严格约束(p 标签语法、无 ::before、无 span margin 等)。
|
||||
* 实测 32 页里能 pass 的不到 30%,剩下的要逐页改造 + 逐页修字体溢出——工时失控。
|
||||
* ✅ 正确做法:切换到 **huashu-slides** skill 的 Path A,按它的 HTML 格式**从头重构**
|
||||
* 每一页。huashu-slides 的 HTML 从一开始就符合 html2pptx 约束,可 100% 导出可编辑 PPTX。
|
||||
* --mode editable 特点:
|
||||
* - 调用 scripts/html2pptx.js 把 HTML DOM 逐元素翻译成 PowerPoint 对象
|
||||
* - 文字是真文本框,PPT 里直接双击能编辑
|
||||
* - ⚠️ HTML 必须符合 4 条硬约束(见 references/editable-pptx.md):
|
||||
* 1. 文字包在 <p>/<h1>-<h6> 里(div 不能直接放文字)
|
||||
* 2. 不用 CSS 渐变
|
||||
* 3. <p>/<h*> 不能有 background/border/shadow(放外层 div)
|
||||
* 4. div 不能 background-image(用 <img>)
|
||||
* - body 尺寸默认 960pt × 540pt(LAYOUT_WIDE,13.333″ × 7.5″)
|
||||
* - 视觉驱动的 HTML 几乎无法 pass —— 必须从写 HTML 的第一行就按约束写
|
||||
*
|
||||
* 依赖:playwright pptxgenjs
|
||||
* npm install playwright pptxgenjs
|
||||
* 依赖:
|
||||
* --mode image: npm install playwright pptxgenjs
|
||||
* --mode editable: npm install playwright pptxgenjs sharp
|
||||
*
|
||||
* 会按文件名排序(01-xxx.html → 02-xxx.html → ...)
|
||||
* 按文件名排序(01-xxx.html → 02-xxx.html → ...)。
