Graphics, Figures & Tables ⇒ Problem with subfig package in twocolumn environment

[Bramschermers]

Hey there,

I'm kind of new to this LaTeX thing and I've started out with the subfigure. I've just found out that this has been replaced by the subfig package, so I switched to this. However unlike the subfigure package (which gave me other problems though) it gives me problems with subfloats in a twocolumn environment. My preamble is as follows:

Code: Select all

documentclass[10pt,a4paper,twoside,twocolumn]{article}
 \usepackage[scriptsize,hang]{caption}												      
 \usepackage[margin=1.5cm,tmargin=3cm, bmargin=2cm]{geometry} 
 \usepackage{graphicx}																			  
 \usepackage{fancyhdr}																			  
 \usepackage{multicol}																			   
 \usepackage[square,comma,sort&compress,nonamebreak]{natbib}																	
 \usepackage{subfig}																				
 \usepackage{hyphenat}
 \usepackage{verbatim}																				
 \usepackage{subeqn}                                          
 \usepackage{appendix}																				
 \usepackage[colorlinks=false,pdfborder={0 0 0}]{hyperref}                                 
 \usepackage[nonumberlist,numberedsection,toc]{glossaries}	

And my piece of problematic figure coding is:

Code: Select all

	\begin{figure}
	\centering
			\subfloat[\emph{Photoelectric effect:} Blablablacaption.\label{fig:photo}]{\includegraphics[width=6cm]{./Robert/photo.jpg}}
			\subfloat[\emph{Compton effect:} Blablablacaption2.\label{fig:compton}]{\includegraphics[width=6cm]{./Robert/compton.jpg}}
			\caption{Gamma-ray interaction effects}
			\label{fig:gammarayeffects}
	\end{figure}

The result is the following (screenshot of pdf):



It's clear to see that the image (figure 5) completely falls off the document on the right side, while I was under the impression the subfig package would automatically detect this and put the subfloats under eachother.

What did I do wrong? (I'm sure it's something easy, but I'm a n00b so I apologize in advance )

Thanks

No, the subfig package does not detect this. TeX is handling such things like paragraph breaking etc.

For TeX a \subfloat is simply a box, just like a simple letter, or a \parbox etc. TeX breakes paragraphs into lines by hyphenation, if it can't do hypenation (like with \subfloat boxes), it tries to break the lines at spaces.

So all you need to do is put some space between the \subfloats so TeX can do an automatic line break here, if necessary.

Please note that \subfloat (as opposite to \subfigure offered by the subfigure package and \subcaptionbox offered by the subcaption package) eats simple spaces (inserted using the space bar key) between them, so you need to place an explicit space here, e.g. \hspace{0.5cm}.
