# A4 to A3 PDF Merger

将多张图片合并为 A3 横向 PDF,每页放置两张图片(左右并排)。

## Usage

### 方法1:使用脚本(推荐)

```bash
python scripts/merge_a4_to_a3.py <图片文件夹> <输出PDF路径> [dpi]
```

示例:
```bash
python scripts/merge_a4_to_a3.py "C:\Users\ZERO\Desktop\质保书" "C:\Users\ZERO\Desktop\输出.pdf"
```

### 方法2:手动生成

如需自定义(如添加白边、调整尺寸),参考脚本逻辑自行修改。

## Output Format

- 页面尺寸:A3 横向(420mm × 297mm)
- 每页:左右两张 A4 图片,无白边
- 分辨率:默认 300 DPI
- 图片按数字顺序排列(1.jpg, 2.jpg, ...)

## Dependencies

- Python 3.x
- Pillow: `python -c "from PIL import Image"` 或 `python -m pip install Pillow`
