EPUB转PDF转换器 2. PDF文件按页码范围拆分 ## 安装依赖 ```bash pip install -r requirements.txt ``` 或者使用uv: ```bash uv pip install -r . ``` ## 使用方法 ### EPUB转PDF ```bash python main.py ``` 示例： ```bash # 转换单个EPUB文件 python main.py books/example.epub # 转换目录下的所有EPUB文件 python main.py books/ ``` ### 拆分PDF文件 ```bash python main.py split <输入PDF文件> <输出PDF文件> <起始页码> <结束页码> ``` 示例： ```bash # 拆分PDF的第5页到第10页 python main.py split input.pdf output.pdf 5 10 ``` ## 依赖库 - ebooklib: 处理EPUB文件 - weasyprint: 将HTML转换为PDF - PyPDF2: 操作PDF文件
