How can I get rid of the extra white space of figures?

Question

My codes are:

\documentclass[aps,pra,twocolumn,margin=1mm]{revtex4-2} 
\usepackage{graphicx}
\usepackage{overpic}
%%%%%%
\begin{document}
  \begin{figure}
    %\centering
    \begin{overpic}[width=3in]{tree.jpg}\put(6,68){(a)}\end{overpic}
    \hspace{-3mm}
    \begin{overpic}[width=3in]{tree.jpg}\put(6,68){(b)}\end{overpic}

    \begin{overpic}[width=3in]{tree.jpg}\put(6,68){(c)}\end{overpic}
    \hspace{-3mm}
    \begin{overpic}[width=3in]{tree.jpg}\put(6,68){(d)}\end{overpic}\end{figure}
\end{document}

And this is what I get

I want to get rid of the useless white edge, I have tried the {standlone}, but something is wrong, so what can I do? The tree picture is:

you are forcing the images to be 3in wide [width=3in] so naturally if the page is wider than 6in you get white space — David Carlisle, Mar 13 '24 at 09:36
also don't do \hspace{-3mm} which i am guessing is trying to compensate for the inter-word space between the images, just omit the space by commenting out the end of lines with % — David Carlisle, Mar 13 '24 at 09:38
It appears that overpic is adding the space internally (bug). If you use \includegraphics by itself, the space goes away. — John Kormylo, Mar 13 '24 at 15:35

If you want that the pictures occupy the whole text width, tell LaTeX so.

\documentclass[aps,pra,twocolumn]{revtex4-2}
\usepackage{graphicx}
\usepackage{overpic}
\usepackage{showframe}
%%%%%%
\begin{document}
\begin{figure*}
\begin{overpic}[width=0.5\textwidth]{tree.jpg}\put(6,68){(a)}\end{overpic}%
\begin{overpic}[width=0.5\textwidth]{tree.jpg}\put(6,68){(b)}\end{overpic}
\begin{overpic}[width=0.5\textwidth]{tree.jpg}\put(6,68){(c)}\end{overpic}%
\begin{overpic}[width=0.5\textwidth]{tree.jpg}\put(6,68){(d)}\end{overpic}
\end{figure*}
\end{document}

The showframe package is loaded just to show the margins of the text block. Don't load it in the final version of your document.

Note that the option margin=1mm is invalid, so I removed it.

I also removed \hspace{-3mm}: the % at the end of the line prevents the space you were trying to cancel out. The second row of picture should be separated by a blank line as in the code above.

Thanks, but it didn't work, it still have extra white space. — karry, Mar 13 '24 at 12:27

This replaces overpic with \llap. I'm not sure if I got the scale the same as overpic.

\documentclass[aps,pra,twocolumn]{revtex4-2}
\usepackage{graphicx}
\usepackage{showframe}
%%%%%%
\begin{document}
\begin{figure*}
\setlength{\lineskip}{0pt}%
\setlength{\unitlength}{0.005\textwidth}%
\includegraphics[width=0.5\textwidth]{example-image}%
\includegraphics[width=0.5\textwidth]{example-image}\llap{% overlap pictures
\makebox[0.5\textwidth][l]{\put(6,68){(a)}}\makebox[0.5\textwidth][l]{\put(6,68){(b)}}}
\includegraphics[width=0.5\textwidth]{example-image}%
\includegraphics[width=0.5\textwidth]{example-image}\llap{% overlap pictures
\makebox[0.5\textwidth][l]{\put(6,68){(c)}}\makebox[0.5\textwidth][l]{\put(6,68){(d)}}}
\end{figure*}
\end{document}
