IronPDF 与 `GrapeCity` PDF：.NET PDF 库对比

IronPDF 提供两种安装方式。对于容器化部署，IronPDF支持 Docker和远程容器操作，以实现灵活的生成：

1. 下载压缩后的源文件。
2. 将文件解压到目录。
3. 进入该目录。
4. 执行run.cmd来构建示例，启动SupportApi服务，并打开 http://localhost:3003。
5. 详情请参阅readme.MD 。

与 IronPDF 相比， GrapeCity PDF 的功能有限。 IronPDF 支持PDF/A 合规性、 PDF/UA 可访问性、自定义纸张尺寸和高级渲染选项。
