[Tex/LaTex] Image caption within \newfloat

captionsfloats

I am using the float package to create my own floats. Now I also want to add an image with its own caption inside, but the caption belongs to the outer float. Is it possible to create something like a figure environment inside my float? I that already but it does not work inside the float.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{graphicx}

\usepackage{blindtext}
\usepackage{float}
\usepackage{framed}

\newfloat{infobox}{tbp}{ext}

\begin{document}

\begin{infobox}
  \begin{framed}
    \blindtext      
    \includegraphics[width=0.85\textwidth]{dummy}
    \caption{Caption for the image}
  \end{framed}
\end{infobox}

\end{document}

Floating environments defined with \newfloat do not respect the position of the \caption command but always use the selected float style instead which have a fixed, pre-defined caption position. They behave differently regarding this aspect than figure and table. (BTW: To make figure and table behave like environments defined with \newfloat, the float package offers \restylefloat.)

So if you want to have a floating environment which behaves like figure and table and let you place the \caption where you want to, do not use \newfloat but \DeclareFloatingEnvironment (or \DeclareCaptionType) offered by the newfloat package, or \DeclareNewTOC offered by the KOMA-Script document classes.

For example:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[demo]{graphicx}% "demo" added because we don't have your picture file

\usepackage{blindtext}
%\usepackage{float}
\usepackage{caption}% caption added since you use it anyway
\usepackage{framed}

%\newfloat{infobox}{tbp}{ext}
\DeclareCaptionType[fileext=ext]{infobox}
  % \newfloat replaced by \DeclareCaptionType

\begin{document}

\begin{infobox}
  \begin{framed}
    \blindtext      
    \includegraphics[width=0.85\textwidth]{dummy}
    \caption{Caption for the image}
  \end{framed}
\end{infobox}

\end{document}

enter image description here

Please note that I've added the caption package since (according your comment) you use it anyway. If you don't use the caption package, the straight-ahead way would be loading the newfloat package and using \DeclareFloatingEnvironment instead.

BUT: If all infoboxes should be framed a different (and IMHO better) approach would be using the boxed style of the float (or floatrow) package:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[demo]{graphicx}

\usepackage{blindtext}
\usepackage{float}

\floatstyle{boxed}
\newfloat{infobox}{tbp}{ext}
\restylefloat*{infobox}
\floatname{infobox}{Infobox}

\begin{document}

\begin{infobox}
  \blindtext      
  \includegraphics[width=0.85\textwidth]{dummy}
  \caption{Caption for the image}
\end{infobox}

\end{document}

(The \restylefloat* is necessary so the caption will be placed inside the frame. Without it the caption would always been outside the frame.)

[Tex/LaTex] Figure caption within enumerate environment

In principle this is just a matter of redefining the printed representation of the figure number by e.g.

\renewcommand{\thefigure}{Q\theenumi(\theenumii)}

(assuming you have just one figure per second level enumeration item, so the actual value of figure is irrelevant). However, if you have figures elsewhere in you document you will get strange numbering of those. So firstly this change should just be applied at the start of enumerate.

However, now the number of the other figures (outside enumerate) jumps over some values. One way around this is to define a newcounter

 \newcounter{curfigure}

save the original value of the figure counter in this at the beginning of the enumerate environment

\setcounter{curfigure}{\value{figure}}

and then restore it at the end via the corresponding \setcounter{figure}{\value{curfigure}}.

with cross references

As you don't want your figures to float, you should use a center environment and \captionof{figure}{....} from the caption package.

The wide figure numbers mean that labels in the list of figures overlap the text in the standard settings for report, so in the code below I have adjusted that too.

\documentclass[10pt,a4paper]{report}

\usepackage{graphicx,caption}

\renewcommand\labelenumi{Q\theenumi.}
\newcounter{curfigure}

\makeatletter
\renewcommand{\l@figure}{\@dottedtocline{1}{1.5em}{3em}}
\makeatother

\begin{document}

\listoffigures

\clearpage

\begin{figure}
  \centering
  Test figure.
  \caption{Test figure.}
  \label{fig:test}
\end{figure}

\begin{enumerate}
\setcounter{curfigure}{\value{figure}}
\renewcommand{\thefigure}{Q\theenumi(\theenumii)}
\item
  \begin{enumerate}
  \item Question 1 Part (a)
  \item Question 1 Part (b)
    \begin{center}
      \centering
      \includegraphics[width=0.2\linewidth]{example-image-a}
      \captionof{figure}{The caption appears as Figure
      Q1(b): instead of Figure 1:}\label{fig:1b}
    \end{center}
  \item Question 1 Part (c)
    \begin{center}
      \centering
      \includegraphics[width=0.2\linewidth]{example-image-b}
      \captionof{figure}{The caption appears as Figure Q1(c): instead
      of Figure 2:}\label{fig:1c}
    \end{center}
  \end{enumerate}
\item
  \begin{enumerate}
  \item Question 2 Part(a)
    \begin{center}
      \centering
      \includegraphics[width=0.2\linewidth]{example-image-a}
      \captionof{figure}{The caption appears Figure Q2(a): instead of
      Figure 3:}\label{fig:2a}
    \end{center}
  \item Question 2 Part(b)
  \end{enumerate}
\end{enumerate}
\setcounter{figure}{\value{curfigure}}

\begin{figure}
  \centering
  Test figure two.
  \caption{Test figure two.}
  \label{fig:test-2}
\end{figure}

\begin{figure}
  \centering
  Test figure three.
  \caption{Test figure three.}
  \label{fig:test-3}
\end{figure}

The figures in the questions are \ref{fig:1b}, \ref{fig:1c}
and~\ref{fig:2a}.

The other figures are \ref{fig:test}, \ref{fig:test-2}
and~\ref{fig:test-3}.

[Tex/LaTex] How to place the figure caption to the left/right? Not aligning, but moving it

A possible, very manual solution:

\documentclass[]{article}

\usepackage{multicol}
\usepackage{duckuments}% for dummy content
\usepackage[]{graphicx}
\usepackage{capt-of}% if you load the caption package you don't need this

\begin{document}
\begin{multicols}{2}
  \blindduck[-]
\end{multicols}
\begin{figure}[htp]% >>>
  \centering
  \includegraphics[width=.7\linewidth]{example-image-duck}%
  \caption
    {%
      A happy duck%
      \label{fig:duck}%
    }%
\end{figure}% <<<
\begin{multicols}{2}
  \blindduck[-]
\end{multicols}
\clearpage
\begin{multicols}{2}
  \blindduck[1-4]
  \vskip\intextsep
  \noindent\begin{minipage}{\linewidth}
    \centering
    \includegraphics[width=.7\linewidth]{example-image-duck}%
    \captionof{figure}
      {%
        A happy canard with a long caption being placed correctly%
        \label{fig:canard}%
      }%
  \end{minipage}
  \vskip\intextsep
  \blindduck[full]
\end{multicols}
\end{document}
