Visual Studio中利用C++调用Python脚本，把xecel导出为png
Visual Studio中利用C/C++调用Python程序，把xecel导出为png
一、依赖项
- vs2019
- Python-3.10.7 (https://www.python.org/downloads/release/python-3107/)
- office2019（python实际上是调用office application 来处理的）
- 安装完python后打开命令行安装需要使用的库
pip install pypiwin32
pip install pywin32
pip install PyMuPDF
二、VS环境配置
- Vs 新建console项目
- 属性-》C/C+±》常规-》附加包含目录
- 属性-》链接器-》常规-》附加库目录
三、代码
