![我可以获得斜体文本的完整对齐吗?](https://linux22.com/image/234445/%E6%88%91%E5%8F%AF%E4%BB%A5%E8%8E%B7%E5%BE%97%E6%96%9C%E4%BD%93%E6%96%87%E6%9C%AC%E7%9A%84%E5%AE%8C%E6%95%B4%E5%AF%B9%E9%BD%90%E5%90%97%EF%BC%9F.png)
在 TeXbook 中,Knuth 指出斜体可能会导致对齐问题:
练习 14.16
当整个段落以斜体或倾斜字体排版时,有时看起来相对于其他段落在页面上偏移。解释如何使用\leftskip
和\rightskip
将段落的所有行向左移动 1pt
。
下面的文字表明,甚至可以得到飘动边距:
\documentclass{article}
\textwidth=3.85cm
\begin{document}
\it\noindent
This is a small text. If jam is what you like, two fingers up,
or whatever. Under certain conditions you see that the left and
right margins flutter.
\end{document}
效果有点被小的 所强调\textwidth
,但编译后并没有显示任何过满的水平盒子。特别是左边距在我看来看起来很糟糕。
有没有办法在 TeX 中解决这个问题?我更喜欢 LaTeX 答案,但最终我对任何 TeX 版本都持开放态度。
我知道这实际上是一个字体问题;这是由于 CM 斜体字体的设计方式造成的。(事实上,我已经问和已回答有关斜体问题的几个问题。)是否存在斜体字体的问题不太明显甚至不存在?
答案1
使用 2.5 版 microtype
包,自 2013 年 3 月 13 日起在 CTAN 上可用,我的问题的简单答案是“使用 microtype
“。
谢谢 Herbert 和 Joseph 告诉我这个microtype
包可以实现。我知道这个包microtype
可以调整边距字距,但我一直以为这只适用于标点符号。实际上,你可以调整每个字母的边距字距。
我一直在想:为什么 Herbert 和 Joseph 的答案中的输出稍好一些,但仍然远远不够好?答案当然是提供的边距字距调整表microtype
不够好。所以我继续浏览了所有字母...输出现在如下所示,我对此非常满意:
以下是代码,主要由调整后的边距字距表组成(现已添加到 microtype
包裹):

答案2
microtype 有一个可选参数,你可以允许将字符向右移动更多,例如[factor=1300]
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{lmodern,picture}
\usepackage{microtype}
\textwidth=3.85cm
\begin{document}
\itshape\noindent\makebox(0,0){\put(\textwidth,-2cm){\line(0,-1){80}}}%
This is a small text. If jam is what you like, two fingers up,
or whatever. Under certain conditions you see that the left and
right margins flutter.
\end{document}
这里的输出带有可选[factor=1100,stretch=80]
参数microtype
答案3
我个人认为使用拉丁现代字体microtype
似乎是更好的方法
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{lmodern,microtype}
\textwidth=3.85cm
\begin{document}
\it\noindent
This is a small text. If jam is what you like, two fingers up,
or whatever. Under certain conditions you see that the left and
right margins flutter.
\end{document}
