将所有图像修剪至参考高度 (\textheight)

Question

我有一系列形状不相同的图像。我想从下方填充（负修剪）图像，使它们都具有相同的形状。我该怎么做？这是我的 MWE

下面是我尝试的片段。我定义了一个变量，referenceheight它0.08\textheight是 的高度版本\textwidth。0.08，因为 1/12 > 0.08，我有 12 个数字。然后我只是对图像进行负填充。它不起作用。

\def\referenceheight{0.08\textheight}
\begin{tikzpicture}[remember picture]
    \node[anchor=south east,inner sep=0] (image) at (0,0) {\frameincludegraphicsblue[width=\imagewidth,pad=0 -\referenceheight 0 0,clip]{example-image-a}};
    \begin{scope}[x={(image.south east)},y={(image.north west)}]
        \node[anchor=south east,draw,fill=white] at (0,0) {Pred};
    \end{scope}
\end{tikzpicture}}

Answer 1

只是一个想法。您可以将图像包含到equal size grouptcolorboxes 中，然后让该tcolorbox包为您完成工作。

\documentclass{article}
\usepackage[most]{tcolorbox}

\tcbset{ size=tight, width=3cm, nobeforeafter, equal height group, halign=center}

\begin{document}
\begin{tcolorbox}
\includegraphics[height=2cm]{example-image-A}
\end{tcolorbox}%
\begin{tcolorbox}
\includegraphics[height=1cm]{example-image-B}
\end{tcolorbox}%
\begin{tcolorbox}
\includegraphics[height=1.7cm]{example-image-c}
\end{tcolorbox}
\end{document}
