我尝试使用命令 \includepdf 和 pagecommand = {} 将我的一篇 mdpi 发表的文章插入到我的博士论文中。但是，这样文档编号和文章编号都会被包含。由于我想删除文章页码，我使用了命令“\pagenumbering{gobble}”。但是，由于文章的页码格式为“page-of-total pages”（例如 1/15、2/15 等），这样我就只剩下“of”了。
知道如何删除它吗？
编辑：我正在提供序言，其中应该包含页面信息，可能隐藏在 mdpi 类文件中。

非常感谢大家！我已经能够通过修改 mdpi.cls 文件来解决这个问题，默认情况下，文章样式附带页码样式，如“1/15”等...
