Graphics, Figures & Tables ⇒ Change of justification to \justified in figure captions

[vichome]

Hi,

How can I change the justification from centered to justified in figure captions?

Document class I use: revtex4-1
Tex Live for Mac

Revtex4-1 does not support the caption package I am using, and the \usepackage command is of no use: justification does change from the original \centered to \raggedright, but not to justified:

Code: Select all

\usepackage[labelfont=bf,labelsep=quad,justification=justified]{caption}

The \Declare command does not help either:

Code: Select all

\DeclareCaptionJustification{justified}{\justified}

Can the problem be solved by \renew commands? If it can and if someone can help, I need a sufficiently detailed description

Many thanks in advance and happy Christmas!
Victor

Hi Victor,

Welcome to the LaTeX community!

As you've already found out caption is not aware of the »revtex4-1« class. I don't think it's easy for a user to change that. I wouldn't use it at all but instead change the internal macro that is responsible for the typesetting of the caption:

Code: Select all

\documentclass{revtex4-1}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{lipsum}% for dummy text

\makeatletter
\renewcommand\@make@capt@title[2]{%
 \@ifx@empty\float@link{\@firstofone}{\expandafter\href\expandafter{\float@link}}%
  {\textbf{#1}}\@caption@fignum@sep#2\quad
}%
\makeatother

\begin{document}

\lipsum[1]

\begin{figure}[ht]
 \rule{5cm}{3cm}
 \caption{\protect\lipsum[2]}
 \label{fig:foo}
\end{figure}

\lipsum[3]

\end{document}

Since the »revtex4-1« class seems to be designed for articles submitted to the American Physical Society or the American Institute of Physics, the captions are designed exactly the way they want it. Why do you want to change them, then? (Or aren't you using the class to submit an article to them?)

Thanks, Clemens -- but I was unable to get the result using the code, even after numerous attempts.

Code: Select all

\makeatletter
    \renewcommand\@make@capt@title[2]{%
     \@ifx@empty\float@link{\@firstofone}{\expandafter\href\expandafter{\float@link}}%
      {\textbf{#1}}\@caption@fignum@sep#2\quad}%
    \makeatother

What I did was to put the code in the preample. I commented the previously used \caption but the other things remained the same, correct?

Code: Select all

(\begin{figure} ... \caption ... \end{figure})

LaTeX reacted to this by changing Figure 1--no full stop -- \quad to FIG. 1. But justification did not change to justified.

Could you please tell where I can find information on the \caption package for TeX Live 2011/2012 to read about the TeX Live inherent caption package?

Your message prompted me to just use \hfil to spread the words along the line so that the figure captions look like justified. I do need to understand how TeX Live's intrinsic \caption works, though, and would appreciate your advice on that.

Frohe Weinachten!

Thanks, Clemens -- but I was unable to get the result using the code, even after numerous attempts.

Could you then post a minimal working example (similar to what I posted, i.e., beginning with \documentclass and ending with \end{document}) so I (or someone else) can see what is going on?

There are in principle two main ways to find information on a package. The first: look on your own computer where the documentation is probably installed. A command line call of the following:

Code: Select all

texdoc caption

should open the caption documentation for instance. If it isn't there there's also http://texdoc.net:

Code: Select all

http://texdoc.net/pkg/caption

should also open the documentation.

Second there's always CTAN (the Comprehensive TeX Archive Network):

Code: Select all

http://www.ctan.org/pkg/caption

Frohe Weinachten!

Thanks! Merry Christmas to you, too

Now your code works! Probably, I missed something when inserting it. Anyway, I have prepared an MWE and would put it on display -- it could be useful to others...

Code: Select all

\documentclass[twoside,rmp, ams]{revtex4-1} 
\usepackage{amsmath, amsfonts, amssymb}
\usepackage{graphicx}
