\\n\\n\\n\\n\\n## 🎬 动画支持\\n\\nOh My PPT 的页面是 HTML 幻灯片，内置本地 **Anime.js v4** 动画运行时。生成或编辑页面时，可以让 AI 为页面里的整块元素添加基础演示动画，例如标题、数据卡片、图片、图表容器、步骤模块等。\\n\\n更推荐使用“整个元素”的动画，而不是把文字拆成很多碎片逐字乱动。这样画面更稳、可读性更好，也更适合汇报、路演和课堂演示。\\n\\n目前更适合使用这些基础整元素动画：\\n\\n- **淡入**：模块出现时轻量过渡。\\n- **轻微位移入场**：从上、下、左、右短距离滑入，适合标题、卡片和列表。\\n- **缩放强调**：关键数字或结论卡片轻微放大后回落。\\n- **简单错峰**：多张卡片或多条要点按顺序依次出现。\\n\\n动画主要用于引导视线和表达层级，不建议做复杂时间线、高频闪烁、无限循环或大幅抖动。页面初始状态也会尽量保持可读，避免“没有动画就看不到内容”的情况。\\n\\n![\\\"Oh](\\\"https://arcsin1.github.io/anime.gif\\\")
\\n\\n\\n## 🦙 支持本地 Ollama 模型（OpenAI 兼容）\\n\\n项目支持通过 **OpenAI 兼容协议** 接入本地 Ollama。\\n\\n在「设置」页面这样填写即可：\\n\\n- `provider`: `openai`\\n- `base_url`: `http://127.0.0.1:11434/v1`\\n- `model`: 你本地拉取的模型名（例如 `qwen2.5-coder:14b`），建议支持 14B+（或云端强模型）\\n- `api_key`: 任意非空字符串（例如 `ollama`）\\n\\n说明：\\n\\n- Ollama 默认不校验 API Key，但应用侧会做“非空”校验，所以不能留空。\\n- 推荐使用 14B+（或云端强模型）做接入生成。\\n- 项目默认不使用 thinking / reasoning 模式。配置自定义 OpenAI 兼容 `base_url` 时，应用会自动请求关闭 thinking，避免工具调用、文档解析和重试生成时出现 `reasoning_content` 兼容问题。\\n\\n\\n\\n## 关于使用问题汇总\\n\\n\\n### 别忘了填写你的配置\\n > 推荐：deepseek v4、kimi、doubao、qwen、glm、xiaomi-mimo、minimax等等更多国产模型、以及gpt、claude、等等国外模型\\n\\n 在「设置」页面填写你的模型配置，否则会报错。 \\n\\n ![\\\"Oh](\\\"./docs/images/3.png\\\")
\\n\\n\\n\\n\\n### 如何添加图片到 PPT 中\\n\\n 注：图片或者素材只会复制到你的本地创意目录，不会上传到云端\\n \\n ![\\\"Oh](\\\"./docs/images/5.png\\\")
\\n\\n\\n### 关于预览模式\\n \\n 支持键盘（左右键）切换，支持演示模式，全屏演示模式，ESC退出演示模式\\n \\n ![\\\"Oh](\\\"./docs/images/2.png\\\")
\\n\\n\\n### 关于导出\\n\\n目前支持三种导出方式：\\n\\n- **PDF**：适合直接分享、归档和打印。\\n- **PNG**：一键批量导出所有页面图片，适合插入文档、Notion、公众号或社媒内容。\\n- **PPTX**：导出为可在 PowerPoint / Keynote 中继续编辑的文件。当前会尽量保留文字、图片、颜色、公式和基础布局，并持续优化文字重叠、混排和复杂图表的效果。\\n\\n\\n\\n## 📦 未签名应用打不开的问题\\n\\n目前发布包可能还没有进行系统级代码签名，所以 macOS 或 Windows 第一次打开时可能会出现安全提示。这个提示通常不是应用损坏，而是系统对“未签名/未公证应用”的默认拦截。\\n\\n### macOS\\n\\n如果 macOS 提示“无法打开”“已损坏”“无法验证开发者”，可以按下面任意一种方式处理。\\n\\n**方式一：右键打开**\\n\\n1. 打开「访达」或「应用程序」文件夹。\\n2. 找到 `OhMyPPT.app`。\\n3. 右键点击应用，选择「打开」。\\n4. 在弹窗里再次点击「打开」。\", \"exit_code\": 0, \"error\": null}",
