Graphics, Figures & Tables ⇒ Package Warning

[stefano91]

Hi everybody!

Compiling my document I get this warning but I can't figure out why, anyone have idea?

Code: Select all

Package caption Warning: The option `hypcap=true' will be ignored for
this (caption) particular \caption on input line 280.

Hi stefano91,

Welcome to the LaTeX community.

Compiling my document I get this warning but I can't figure out why, anyone have idea?

Not without a minimal working example. All I can say is that something's going wrong with the hyperlink there.

Regards

thank you!

Not really minimal, this example, is it? Anyway: a minimal example to reproduce the warning is this one:

Code: Select all

\documentclass{article}
\usepackage{caption}
\usepackage{listing}
\usepackage{hyperref}
\begin{document}

\begin{listing}
 foo
 \caption{bar}\label{lst:bar}
\end{listing}

See listing~\ref{lst:bar}

\end{document}

Note, that I placed hyperref as last package to be loaded which is usually a good idea.

I am not really familiar with the hypcap package but its purpose is to redirect a hyperlink not to the caption but to the beginning of the float. As it seems you don't load the »hypcap« package so you can safely ignore the warning. If you load »caption« with the option hypcap=false the warning will disappear.

Code: Select all

\documentclass{article}
\usepackage[hypcap=false]{caption}
\usepackage{listing}
\usepackage{hyperref}
\begin{document}

\begin{listing}
 foo
 \caption{bar}\label{lst:bar}
\end{listing}

See listing~\ref{lst:bar}

\end{document}

On the other hand you could load »hypcap« (after »hyperref«, this is one of the exceptions) and place \capstart where you want the hyperlink to be directed to:

Code: Select all

\documentclass{article}
\usepackage{caption}
\usepackage{listing}
\usepackage{hyperref}
\usepackage{hypcap}
\begin{document}

\begin{listing}
 \capstart
 foo
 \caption{bar}\label{lst:bar}
\end{listing}

See listing~\ref{lst:bar}

\end{document}

Sorry I just didn't know what was importan and what wasn't!
Also I had no idea what hycap was!

Anyway adding hycap=false as option of captation the warning disappeard.

I knew was nothing vital, but I wanted to understeand!

Thank you!

If you had read the side about the minimal working example (MWE) that cgnieder linked to, you would know how to make your code into a MWE; you should have used the hacking down approach.

Yes, the warning has disappeared, but the "hypcap" feature, too. This means now all hyperlinks to figures and tables will jump to the caption of the figure and table instead to the figure or table itself.

An except of the caption package manual, appendix "A.3 Warnings":

"The option ‘hypcap=true’ will be ignored for this particular \caption."

The caption package hasn’t found a proper hyperlink anchor for this particular caption, so it decides to ignore the setting hypcap=true (which is set by default). As a result a link to this caption (e.g. in the List of Figures, or set by \ref or \autoref) will link you to the caption of the figure or table, not to the figure or table itself.

This can happen if you use \captionof inside a non-floating environment, but also if you use some package which redefines figure or table, and which is unknown to the caption package.

If this is ok for you but you want to suppress this warning, simply place a \captionsetup{hypcap=false} just before the \caption or \captionof command which is causing the warning. If this is not ok for you, you can set a hyperlink anchor with \captionsetup{type= float type } for yourself.
