在简单字母内实现 FCOLORBOX 的移位

考虑一下代码

\documentclass{book}
\usepackage{type1cm,lettrine}
\usepackage{xcolor}
%\usepackage{lipsum}
\usepackage[tracking=true]{microtype}

\begin{document}
\thispagestyle{empty}
\large

\lettrine[lines=3,loversize=.4,lraise=.15,nindent=.80em,findent=.20em]{\fboxsep10pt\fboxrule15pt\fcolorbox{red}{yellow!75!brown}{\color{red}I}}{would} like to shift (vertically, horizontally) the yellow box containing the letter within the outer red box.
\end{document}

问题：我怎样才能水平（和垂直）移动fcolorbox外部红框内的字母？

编辑：不重新定义 fcolorbox 可以做到这一点吗？

我使用 编译了代码pdflatex。

谢谢。

答案1

\fcolorbox将绘制一个在所有方向上具有相同内部填充和边框宽度的框。

允许longbox您分别设置填充和边框的顶部、底部和左侧的宽度。然后可以通过操纵这些参数将内部黄色框移动到外部红色框内。

使用外部红色框的左下角作为原点来定义两个长度\xshift和。\yshift

原图的\fcolorbox边框为 15pt，内边距为 10pt。图中显示其longbox忠实再现了原图。

A

显然，在这个例子中，偏移的最大值为 25pt，以将黄色框保持在红色框内。

第二张图显示了三个例子。depth=1添加了第四行。
