如何使用 mdframed 包重现 tcolorbox 文档中漂亮的 LIB 样式框？

Question

我尝试使用 mdframed 包重现 tcolorbox 文档中漂亮的 LIB 类型框。但我失败了，我不知道如何使用 mdframed 包生成剪辑效果。旋转后的矩形比背景框大……

我的代码：

% !Tex program    = xelatex
% !Tex encoding   = UTF-8 Unicode
\documentclass{article}
\usepackage{xcolor}
\usepackage{tikz}
\usetikzlibrary{calc}
\usepackage[absolute,overlay]{textpos}
\usepackage[skins]{tcolorbox}
\usepackage[framemethod=TikZ]{mdframed}
