补丁修改 - Office Open

patchPresentation 先把 .pptx 解析成 PresentationOptions，再按顺序执行命令并重新生成包。未编辑的 canonical 字段会保留来源 round-trip 信息。

import { patchPresentation } from "@office-open/pptx";

const result = await patchPresentation({
  data: deck,
  commands: [
    {
      type: "replace",
      at: { field: "slides", route: [{ index: 0 }], text: { placeholder: "title" } },
      value: "Quarterly Review",
    },
    {
      type: "insert",
      at: { field: "slides" },
      position: "end",
      value: [{ children: [{ shape: { x: 0, y: 0, width: "10cm", height: "2cm" } }] }],
    },
    { type: "remove", at: { field: "slides", route: [{ index: 1 }] } },
    { type: "update", at: { field: "title" }, set: "Board Deck" },
  ],
});

幻灯片路由支持 index、id 和 name；嵌套路由可以定位 children、comments、版式、母版和其他 canonical 集合。宏文档和模板文档需要设置 packageVariant。
