# PPT 制作优化工作流

> **Version**: 1.0 | **Created**: 2026-01-21 | **优先级:Nano Banana Pro → Processing → PPT组装**

---

## 🎯 核心原则

### 工作流程

```
1️⃣ 需求分析 → 2️⃣ Nano Banana Pro 生成页面图片 → 3️⃣ Processing 生成动态效果 → 4️⃣ 组装 PPT → 5️⃣ 导出双格式(.pptx + 图片)
```

### 技术栈优先级

1. **Nano Banana Pro** - 图片生成、整体页面设计(最高优先级)
2. **Processing** - 动态效果、粒子系统、流场动画
3. **Python-pptx** - 最终组装成 PPT 文件

---

## 📋 详细步骤

### Step 1: 需求分析和规划

**输入**: 用户的 PPT 需求描述

**输出**: 结构化的 PPT 大纲

**操作**:
```markdown
# PPT 大纲
- 总页数: N 页
- 风格主题: [科技感/商务风/创意艺术/...]
- 动态效果需求: [粒子背景/流场动画/数据可视化/...]
- 配色方案: [主色调+辅助色]
```

**关键决策**:
- 哪些页面需要静态设计(Nano Banana Pro)?
- 哪些页面需要动态效果(Processing)?
- 哪些页面需要数据可视化(图表)?

---

### Step 2: Nano Banana Pro 生成页面图片

**优先使用场景**:
- ✅ 封面页、标题页
- ✅ 内容页整体设计
- ✅ 复杂布局页面
- ✅ 需要高质量视觉设计的页面

**命令模板**:
```bash
# 生成单页设计
uv run ~/.claude/skills/nano-banana-pro/scripts/generate_image.py \
  --prompt "Professional PPT slide design: [页面主题], [风格描述], 16:9 aspect ratio, clean layout, [配色方案]" \
  --filename "$(date +%Y-%m-%d-%H-%M-%S)-slide-[N]-[描述].png" \
  --resolution 4K

# 示例:生成封面页
uv run ~/.claude/skills/nano-banana-pro/scripts/generate_image.py \
  --prompt "Professional tech-themed PPT cover slide: 'Data Analysis Report 2024', dark background with electric blue accents, minimalist design, 16:9 format" \
  --filename "2026-01-21-10-30-00-slide-01-cover.png" \
  --resolution 4K
```

**提示词最佳实践**:
- 明确指定 16:9 宽高比
- 包含风格关键词(professional, minimalist, tech-themed)
- 描述配色方案
- 指定文字位置和大小(large title at top, bullet points on left)

**文件命名规范**:
```
YYYY-MM-DD-HH-MM-SS-slide-[序号]-[描述].png
```

---

### Step 3: Processing 生成动态效果

**适用场景**:
- ✅ 背景动画(粒子系统、流场)
- ✅ 过渡动画(章节分隔页)
- ✅ 数据可视化动画
- ✅ 装饰性图形元素

**调用 Processing Skill**:
```bash
# 生成粒子背景动画
# Processing skill 会自动激活,直接描述需求即可
"Create a particle system background with electric blue particles on dark background, 1920x1080, export as PNG"
```

**输出格式**:
- 静态图: PNG
- 动画: GIF(如果 PPT 支持)
- 帧序列: 多张 PNG(用于复杂动画)

**配色对齐**:
- 确保 Processing 生成的效果与 Nano Banana Pro 的配色方案一致
- 从 Nano Banana Pro 图片中提取主色调,传递给 Processing

---

### Step 4: 组装 PPT

**使用 Python-pptx**:

```python
from pptx import Presentation
from pptx.util import Inches
from PIL import Image

def create_presentation_from_images(image_paths, output_filename):
    """
    将图片组装成 PPT

    Args:
        image_paths: 图片路径列表 (按页面顺序)
        output_filename: 输出的 PPT 文件名
    """
    prs = Presentation()
    prs.slide_width = Inches(10)   # 16:9 宽度
    prs.slide_height = Inches(5.625)  # 16:9 高度

    for img_path in image_paths:
        # 使用空白布局
        slide_layout = prs.slide_layouts[6]
        slide = prs.slides.add_slide(slide_layout)

        # 获取图片尺寸
        img = Image.open(img_path)
        img_width, img_height = img.size
        aspect_ratio = img_width / img_height

        # 计算适配尺寸(铺满整个幻灯片)
        slide_width = prs.slide_width.inches
        slide_height = prs.slide_height.inches

        # 添加图片(铺满背景)
        slide.shapes.add_picture(
            img_path,
            left=0,
            top=0,
            width=Inches(slide_width),
            height=Inches(slide_height)
        )

    # 保存 PPT
    prs.save(output_filename)
    print(f"✅ PPT 已生成: {output_filename}")
    return output_filename
```

**脚本位置**:
```
E:\Bobo's Coding cache\scripts\ppt\assemble_ppt_from_images.py
```

---

### Step 5: 导出双格式

**必须输出**:
1. **PPT 文件**: `output.pptx`
2. **图片文件夹**: `output_slides/`
   ```
   output_slides/
   ├── slide-01-cover.png
   ├── slide-02-agenda.png
   ├── slide-03-content.png
   └── ...
   ```

**导出脚本**:
```python
def export_slides_as_images(pptx_file, output_dir):
    """
    从 PPT 导出每一页为图片

    使用 LibreOffice 转换:
    soffice --headless --convert-to pdf output.pptx
    pdftoppm -png -r 300 output.pdf output_slides/slide
    """
    import subprocess
    import os

    os.makedirs(output_dir, exist_ok=True)

    # 转换为 PDF
    subprocess.run([
        'soffice', '--headless', '--convert-to', 'pdf', pptx_file
    ])

    pdf_file = pptx_file.replace('.pptx', '.pdf')

    # PDF 转图片
    subprocess.run([
        'pdftoppm', '-png', '-r', '300', pdf_file,
        f'{output_dir}/slide'
    ])

    print(f"✅ 图片已导出到: {output_dir}")
```
