我正在尝试为一些照片创建一些好看的标题。我不想调整这些照片的纵横比，所以我keepaspectratio在 中包含了该选项\includegraphics。
受到 Martin Scharrer 的回答的启发浮动的自动宽度，我使用一个保存框来捕获照片的宽度，然后在命令中使用此宽度\captionsetup。这种方法效果很好，但我注意到一个相当奇怪的现象：
- 如果将宽度选项
\includegraphics设置为width=1\textwidth，则所有内容都会按应有的方式编译。 - 如果将宽度选项
\includegraphics设置为width=a\textwidth，其中 a 小于 1，则标题将向右偏移约 2pt，因此无法在图像下方正确居中。 - 如果将宽度选项
\includegraphics设置为width=b\textwidth，其中 b 大于 1，则标题和图像之间会有少量空白（尽管在这种情况下标题不会偏移）。
以下是 MWE：

There will be some text on the left side of the page. The start of this text needs to be vertically aligned with the top of the other minipage.

答案1
另一种方法是图形及其标题都由自定义排版\tcbox。注意tcolorbox不会使用caption包完成的标题设置，因此您必须自己动手。
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{tgbonum}
\usepackage{tcolorbox}
\tcbuselibrary{skins}
\definecolor{captionColor}{RGB}{103,143,150}
\newtcbox[use counter*=figure, list inside=lof]\tcbfigure[1]{
enhanced,
nobeforeafter,
colback=captionColor,
colbacktitle=captionColor,
arc=0pt,
outer arc=0pt,
boxrule=0pt,
boxsep=0pt,
leftupper=0pt, rightupper=0pt,

答案2
这个答案仅有的解决了第一个问题，
当宽度 < 线宽时，标题向一侧偏移
该caption选项width=<length>不仅设置了字幕的宽度，还可以设置字幕的居中位置，您看到的就是居中效果。
要控制标题宽度和左边距，请使用margin={0pt, \dimexpr\linewidth-<desired width>}。
演示居中对齐的示例width=<length>：
\documentclass{article}
\usepackage{caption}
\usepackage[pass, showframe]{geometry}
\usepackage{graphicx}
\usepackage[T1]{fontenc}
\begin{document}
\captionsetup{type=figure, width=3cm}
\includegraphics[width=3cm]{example-image}
\caption{|text\hfill text|}
\captionsetup{type=figure, width=6cm}
\includegraphics[width=6cm]{example-image}
\caption{|text\hfill text|}
\end{document}
您的示例中，使用margin={0pt,\dimexpr\linewidth-\wd\placeHolder(One|Two)}而不是width=\wd\placeHolder(One|Two)，文档类，以及而不是 的article图像：example-image-[ab]examplePhoto[12]
