captionsfloats
I want to have to following text at my figures:
<< FIGURE >>
Figure 1: Title of my figure which is displayed in the list of figures
Here in a new line a long description about the figure, in a smaller text
I've found this one:
\caption[Title of my figure which is displayed...]%
{Here in a new line a long...}
The problem with the given code is that I get not the title under my figure, only "Figure 1: Here in a new line a long…".
How to solve this? Thank you!
The default definition of \caption in article and the other standard classes is not boxed if the caption is more than a line. To change the effective line width you should use quote (or an environment with similar definition) which is
\newenvironment{quote}
{\list{}{\rightmargin\leftmargin}%
\item\relax}
{\endlist}
Which just accepts the default increase of \leftmargin and makes \rightmargin the same. You can set the two margins explicitly to any appropriate value in the definition of a custom environment to wrap the caption
\begin{center}
\includegraphics
\nopagebreak
\begin{quote}
\captionof{figure}{looooong caption}
\end{quote}
\end{center}
Instead of manipulation the original \caption command it might be easier to define a new command which handles the two arguments as intended.
\documentclass{article}
\newcommand\mycaption[2]{\caption{\textbf{#1}\newline\small#2}}
\begin{document}
\begin{figure}
\mycaption{Caption title}{I would like this sentence to be under the title and smaller.}
\end{figure}
\end{document}

Use the
\captionmacro for the (short) "heading" of the figure and just add the longer description into thefigureenvironment (after the\captionand with proper vertical spacing).
