如何在 \begin{document} 之前在 tcolorbox 环境中插入图形

Question

为了在我的表单中插入徽标图片，我想使用 tcolorbox，但我不知道如何创建一个新环境以将其包含在 \begin{document} 之前的节点内。

这是我的代码，可以用 xelatex 正确编译

当我编译此代码时，我得到以下文档 有人能帮忙去掉图片左边空白处吗？非常感谢。

Answer 1

我想你想要这样的东西。我定义了一个myboxedlogo带有三个参数的命令：可选的 tcolorbox 参数、includegraphics 参数和图形名称。此命令用于将徽标包含在主页和左边距中。

顺便说一句，tcolorbox我没有使用命令，而是使用了tcbincludegraphics命令。
