[Tex/LaTex] How to make the figure float [H] here when I use SCfigure

floatsgraphics

When I was using \begin{figure}....\end{figure}, I was able to fix the figure in the location using the [H], [h], or [h!] options, but that doesn't work when I use SCfigure. How do I fix a SCfigure in place?

\documentclass[12 pt , twoside, a4paper] {article}
\usepackage[pdftex]{graphicx}
\usepackage{sidecap}
\begin{document}
\begin{SCfigure}
\includegraphics[scale=0.5]{EffectiveArea}
\caption{height of cylinder=v$\Delta$t  \newline
volume of cylinder=$\pi (2r)^2(v\Delta t)$  \newline
number of collision per second=$\frac{N}{V_{molecule}}V_{cylinder}
\newline \quad \quad \quad \quad =\frac{N}{V_{molecule}}\pi (2r)^2(v\Delta t)$}
\end{SCfigure}
\end{document}

And the error is: ! LaTeX Error: \caption outside float.

If you still want to use the old package sidecap, remember that the floating specifier is the second optional parameter of SCfigure, so you have to use it as, for example,

\begin{SCfigure}[][h]

if you want the h specifier.

Also sidecap seems not to be compatible with float, so the H specifier cannot be used.

MWE:

\documentclass[12 pt , twoside, a4paper] {article}
\usepackage[pdftex,demo]{graphicx}  %remove demo option in your document
\usepackage{sidecap}
\begin{document}
\begin{SCfigure}[][h]
\includegraphics[scale=0.5]{EffectiveArea}
\caption{height of cylinder=v$\Delta$t  \newline
volume of cylinder=$\pi (2r)^2(v\Delta t)$  \newline
number of collision per second=$\frac{N}{V_{molecule}}V_{cylinder}
\newline \quad \quad \quad \quad =\frac{N}{V_{molecule}}\pi (2r)^2(v\Delta t)$}
\end{SCfigure}
\end{document}

Otherwise you can switch to the floatrow package as mentioned in Bernard's comment and, issuing a command like

\floatsetup[figure]{capposition=beside,capbesideposition={top,right}}

you can obtain the same (probably better) result using the figure environment.

MWE:

\documentclass[12 pt , twoside, a4paper] {article}
\usepackage[pdftex,demo]{graphicx}  %remove demo option in your document
\usepackage{floatrow}
\floatsetup[figure]{capposition=beside,capbesideposition={top,right}}
\begin{document}
\begin{figure}[h]
\includegraphics[scale=0.5]{EffectiveArea}
\caption{height of cylinder=v$\Delta$t  \newline
volume of cylinder=$\pi (2r)^2(v\Delta t)$  \newline
number of collision per second=$\frac{N}{V_{molecule}}V_{cylinder}
\newline \quad \quad \quad \quad =\frac{N}{V_{molecule}}\pi (2r)^2(v\Delta t)$}
\end{figure}
\end{document}

Output:

[Tex/LaTex] Conflict between color, graphicx and libertine

These option clashes happen when a package is requested to be loaded on two different positions, like by you and inside another package, but with different options. The package is loaded by the first \usepackage (or its twin \RequirePackage); it isn't loaded again when it is requested again. It simply can't be loaded a second time. Therefore the new options can be activated and previous options might conflict with the second usage. So LaTeX creates an error to report this issue to you.

The way to fix this is to declare the options beforehand using \PassOptionsToPackage{<options>}{<package>}. Then they are used wherever the package is loaded.

\documentclass{article}
\usepackage{ifpdf}
\ifpdf
    \PassOptionsToPackage{pdftex,usenames,dvipsnames}{color}
    \usepackage[T1]{fontenc}
    \usepackage{libertine} % most likely loads 'color' itself
    %\usepackage{lmodern} % doesn't load 'color'
    \usepackage{color}
    \usepackage[pdftex]{graphicx}
\else
    %\bye
\fi
\begin{document}
Hello, world!
\end{document}

I can't test it by myself, because I don't have the libertine package installed.

PS:

I don't think you need to set pdftex manually. Normally packages do a good job recognizing the driver by themselves. Also you might want to use the extended xcolor package instead of color.

[Tex/LaTex] How to float figure within multicol text

There are a couple of possibilities here. For two-column text in the article class, you don't need the multicols environment other than to balance the columns at the end, or if you want to switch to single-column and back without incurring a page break. Just pass the twocolumn option to article. In that case, using the figure environment will indeed give you a single-column floating figure (that will usually appear at the top of the next column, but you can tweak the positioning if you need to).

Second, if you truly need the multicols environment, then the package documentation states that single-column floats are incompatible with multicols. You can use the starred forms (figure* or table*) which will take up a full page width, as @Frg points out. As it turns out, positioning floats is very complicated, and made even more so in the multi-column case. See for instance this document, which documents some of the challenges involved; both this document and the multicol package were written by Frank Mittelbach, who is heavily involved in the LaTeX3 effort, so I'd guess that if multicol doesn't support floats yet, it's still not a solved problem :)

Finally, you can abandon flexibility, and resort to trial-and-error: move the content you wish to float around in your source, and recompile and try again until it looks good. If this is your only viable approach, I'd suggest waiting until the surrounding text has mostly stabilized, so you don't waste time perfecting a layout that will just break with the next edit...
