两张图片的页眉和页脚均未显示

Question

我想在 LaTex 中制作这个模板，在页眉两侧加上两个徽标，并在示例中加上小页脚，但是，我尝试使用 fancyhdr 并设置一个新的样式页面或单独放置图像，但什么也没发生。

我想要实现的例子：

我的进步：

Answer 1

一些观察：

• 您可以为首页定义一个特殊的页面样式（我假设您只希望在第一页上使用此页眉）。您可以使用 来执行此操作\fancypagestyle。但这需要\headheight在此页面上使用与其他页面不同的页面样式。这是可以做到的，但很棘手。因此，我建议将此页眉放在普通文本主体中，并在该页面上放置一个空的真实页眉（具有特殊的页面样式）。这就是我在我的解决方案中所做的。
• 您可以使用 定义各种页面参数\setlength，但使用 参数来定义会更好geometry。否则，您将使用两种不同的机制，这可能会导致冲突。 也是如此\special{papersize=8.5in,11in}。这就是geometry您要做的。所以我注释掉了这些。
• 我将整个可选参数放在\twocolumn括号中{}，以便可以在里面使用方括号。

考虑到这一点，他是我的解决方案：
