![a0poster.cls 中的定位或边距问题](https://linux22.com/image/474076/a0poster.cls%20%E4%B8%AD%E7%9A%84%E5%AE%9A%E4%BD%8D%E6%88%96%E8%BE%B9%E8%B7%9D%E9%97%AE%E9%A2%98%20.png)
我想用 a0poster.cls 创建一个海报模板(https://www.ctan.org/tex-archive/macros/latex/contrib/a0poster) 并开始设置背景。
为什么定位命令无法正常工作?所有东西都向左和向下移动。类代码中是否有导致这种情况的原因?
