如何水平“挤压”字体？

Question 1

您可以ExtendFont在地图声明中使用。但由于这只会改变字形而不会改变其指标，因此您可能必须将其与一些负面跟踪相结合（除非您想创建新的 tfm 文件）。0.55 是一个夸张的值，它只会更好地显示效果：

\documentclass{scrartcl}
\usepackage[T1]{fontenc}

\usepackage{microtype}
\pdfmapline{=LinLibertineMT-tlf-t1--base LinLibertineMT ".55 ExtendFont AutoEnc_d6jdytwuqqz4y7d6afmjlfgx7d ReEncodeFont " <[lbtn_d6jdyt.enc <LinLibertineMT.pfb }    

    \usepackage[
        osf,
        ttscale=0.875,
    ]{libertine}



\begin{document}\pagestyle{empty}
    \begin{itemize}
        \item[normal font:] {\normalfont abcdefghijklmnopqrstuvwxyz}
        \item[monospaced font:]  {\ttfamily abcdefghijklmnopqrstuvwxyz}\\
                                 {\textls[-100]{\ttfamily abcdefghijklmnopqrstuvwxyz}}
        \item[x-height comparison:] {\ttfamily x}{\normalfont x}{\ttfamily x} {\ttfamily X}{\normalfont X}{\ttfamily X}
    \end{itemize}
\end{document}

Question 2

基于Ulrike 的回答和评论，这里是解决方案的 MWE主观上满足了我的要求。

我使用了.875打字机字体的全局缩放因子（作为libertine包的全局选项）和ExtendFont地图声明中的因子。

然后我声明\DeclareMicrotypeSet字体ttfamily（注意encoding=*明确似乎是必需的），我通过将字母间距减少 0.1em（参见{-100}）以及将单词间距减少 50%（参见-500*）并将收缩率提高 10%（100*）来调整它的跟踪。

关键是设置这些设置后已加载libertine（你在这里，哦，浪费了两个小时！）

\documentclass{scrartcl}

    \usepackage[T1]{fontenc}
    \usepackage[tracking]{microtype}
    \usepackage[ttscale=0.875]{libertine}

    \pdfmapline{=LinLibertineMT-tlf-t1--base LinLibertineMT ".875 ExtendFont AutoEnc_d6jdytwuqqz4y7d6afmjlfgx7d ReEncodeFont " <[lbtn_d6jdyt.enc <LinLibertineMT.pfb }    
    \DeclareMicrotypeSet*[tracking]{typewriter}{ encoding = *, family = tt* }
    \SetTracking[ spacing = {-500*,,100*} ]{ encoding=*, family = tt* }{-100}

\begin{document}

    \begin{itemize}
        \item[normal font:] {\normalfont abcdefghijklmnopqrstuvwxyz}
        \item[monospaced font:] {\ttfamily abcdefghijklmnopqrstuvwxyz}
        \item[x-height comparison:] {\ttfamily x}{\normalfont x}{\ttfamily x} {\ttfamily X}{\normalfont X}{\ttfamily X}
    \end{itemize}
