减少横向模式下图片之间的距离

Question

我需要减少横向模式下两张图片之间的距离。我认为如果没有不必要的间距，它们应该可以放在页面上。 \hspace{.25cm} 也不起作用。请参阅下面的代码。并附上两张图片，如果有帮助的话...

我希望它们彼此相邻，就像这里一样，但它们之间没有间距：

graphicx我无法使用带有选项的包提供的测试图像重现您的结果demo。

\documentclass[a4paper, 12pt]{article}
\usepackage{geometry}
\geometry{a4paper, top=30mm, left=30mm, right=30mm, bottom=30mm,headsep=10mm, footskip=12mm}
\usepackage[demo, export]{adjustbox}
\usepackage{subcaption}
\usepackage{pdflscape}

\begin{document}

\newgeometry{top=30mm, left=10mm, right=10mm, bottom=30mm,headsep=10mm, footskip=12mm}
\begin{landscape}
\begin{figure}
\begin{subfigure}{0.49\linewidth}
    \includegraphics[width=\linewidth]{heatmap_bull_unscaled.png}
\caption{Sub figure A}
    \label{fig:sub1}
\end{subfigure}
\hfill
\begin{subfigure}{0.49\linewidth}
    \includegraphics[width=\linewidth]{heatmap_bear_unscaled.png}
\caption{Sub figure B}
    \label{fig:sub2}
\end{subfigure}
\caption{Figure in landscape orientation}
    \label{fig:sub2}
\end{figure}
\end{landscape}

\restoregeometry
\end{document}

如果你无法用实际图像重现类似的结果，则意味着图像周围有空白。你可以使用 enclose \incledegraphics...into 来检查这一点\fbox：

\begin{subfigure}{0.49\linewidth}
\fbox{
    \includegraphics[width=\linewidth]{heatmap_bull_unscaled.png}
    }
\caption{Sub figure A}
    \label{fig:sub1}
\end{subfigure}

如果存在空白，您可以用生成它们的程序中的工具将其修剪掉，或者使用其他工具或使用以下选项的适当trim设置\includegraphics：

\includegraphics[trim={5cm 0 0 0},clip]{example-image-a}

在哪里修剪修改文件中指定的边界框。这四个值指定要从原始框的左侧、底部、右侧和顶部移除的数量；以及夹子将图形剪贴到边界框（用 trim 指定）
