I'm trying to text-wrap floating images in LaTeX, using code like the following:
\begin{wrapfigure}{R}{0.5\textwidth}
\begin{center}
\includegraphics{images/image.png}
\caption{This is the caption.}
}
\label{fig:image1}
\end{center}
\end{wrapfigure
This works fine most of the time (creating an image that floats on the right-hand side), but sometimes LaTeX does not properly clear after the image, and it leaves an open column for another page or two. How does one remedy this, or ideally, does LaTeX have a function similar to clear: both in CSS?
There is the \clearpage command, but it's not appropriate when there's no natural place to break to a new page near the image.
You might try to manually set the height of the figure using the optional argument of wrapfigure
\begin{wrapfigure}[lineheight]{alignment}{width}
where lineheight is the number of text lines which shall wrap around the image.
I still don't have a good answer to this question, but the solution for now is to not use wrapfigure at all. Using only figure solves the problem of open columns, but it's not the most ideal solution. Any other answers are still welcome, but I'll post my half-way solution here for those who might also need it:
\begin{figure}
\begin{center}
\includegraphics{images/image.png}
\caption{This is the caption.}
\end{center}
\label{fig:image1}
\end{figure}

I'm using the print function in MATLAB to write images of plots, something like that
print(figure(1),'-dpng','-r300',filename);
But apparently the images are not overwritten, and the original images stay. I was using saveas before, which seems to overwrite the images, but print gives me more output options. Any ideas?
UPDATE: I ended up deleting the files before the printing with a different function.
You can use this:
im = frame2im(getframe(gcf,rec)); %Grabs image of plot as an image
imsave(im, filename); %save image
That syntax may not be 100%, its a while since I've used it.
Also be aware that this isn't perfect - I remember having issues with it grabbing a grey border around the edge of the plot. Also, I think the image may be based on a matlab screenshot.... just something to be aware of
Saving figures in matlab is rather troublesome, especially if the saved image should look like the original figure.
For myself i found the solution in using export_fig.
It's one of the most downloaded fileexchange files - maybe you should give it a try:
http://www.mathworks.de/matlabcentral/fileexchange/23629-export-fig
A small introduction to export_fig can be found at:

I'm trying to make a presentation using the Beamer class. I want to show a simple list of images, one by one in one frame, just like when you use itemize<+->.
I have no problem showing the images one-by-one, but the images shifts every time I insert a new image. How do I solve this - From my perspective there must be a simple solution, without specifying the absolute placement of the images.
You can simply specify a series of images like this:
\includegraphics<1>{A}
\includegraphics<2>{B}
\includegraphics<3>{C}
This will produce three slides with the images A to C in exactly the
same position.
I found a solution to my problem, by using the visble-command.
EDITED:
\visible<2->{
\textbf{Some text}
\begin{figure}[ht]
\includegraphics[width=5cm]{./path/to/image}
\end{figure}
}
\includegraphics<1>{A}%
\includegraphics<2>{B}%
\includegraphics<3>{C}%
The % is important. This will keep all the images fixed.
This is what I did:
\begin{frame}{series of images}
\begin{center}
\begin{overprint}
\only<2>{\includegraphics[scale=0.40]{image1.pdf}}
\hspace{-0.17em}\only<3>{\includegraphics[scale=0.40]{image2.pdf}}
\hspace{-0.34em}\only<4>{\includegraphics[scale=0.40]{image3.pdf}}
\hspace{-0.17em}\only<5>{\includegraphics[scale=0.40]{image4.pdf}}
\only<2-5>{\mbox{\structure{Figure:} something}}
\end{overprint}
\end{center}
\end{frame}
This is a sample code I used to counter the problem.
\begin{frame}{Topic 1}
Topic of the figures
\begin{figure}
\captionsetup[subfloat]{position=top,labelformat=empty}
\only<1>{\subfloat[Fig. 1]{\includegraphics{figure1.jpg}}}
\only<2>{\subfloat[Fig. 2]{\includegraphics{figure2.jpg}}}
\only<3>{\subfloat[Fig. 3]{\includegraphics{figure3.jpg}}}
\end{figure}
\end{frame}
I want to create something like a leaflet/magazine using Latex. Is it possible to place text on top of an image and style the text freely?
Any links to examples of something like this?
I usually do something like
\usepackage{tikz}
...
\begin{tikzpicture}
\draw (0, 0) node[inner sep=0] {\includegraphics[width=4cm]{imagefile.png}};
\draw (1, 1) node {Hello world};
\end{tikzpicture}
A very good toolset for manipulating images is pgf/TikZ pdf doc.
See \pgfimage for examples. It allows to mix text and image freely. There are many ways to do it. One of them is to use layers (p. 220 of pgfmanual). The pgf manual contains many simple examples, and is very precise.
Another solution is to use the lpic package: the homepage contains some examples.
You can find other examples for pfg and TikZ here and here for many impressive examples.
You can also define the text after the image and then offset it using negative vertical space. Because it follows after the image in the LaTeX source, it will be drawn on top of the image instead of underneath it.
\includegraphics[...]{...}
\vspace*{-20ex} % Tune this to the image height.
\begin{center}
Text
\end{center}
\vspace*{20ex} % The spacing above but without the minus.
Another solution is the textpos package which allows you to specify boxes at absolute positions on the page. The boxes can overlap, so you can put the figure in one box, and text in another box on top of it.
I realise that the question is old and answer is accepted, but for completeness would like to propose an alternative approach for making leaflets in LaTeX.
Specifically, the leaflet document style served me really well for this purpose.
A good blog post wrt background image can be found here. There are a couple of packages that are required to use in order to make the proposed approach work, but were not mentioned in the blog post:
\usepackage[usenames,dvipsnames]{xcolor}
\usepackage{transparent}
As already suggested, you can annotate the different parts of the figure using TikZ. However, sometimes it might even better to use numbers to reference the different parts and explain them in the figure caption.
To easily get the precise relative positions (which is often tedious) and to generate LaTeX code automatically, you could use the new web-based LaTeX Overlay Generator, which I built for such cases. This is just a small interactive tool, which helps you to find the right locations.
Another way to do this, admittedly not using LaTeX, would simply be to edit the image with photoshop or gimp or something like that. I guess your option in terms of typesetting mathematics might be fairly limited doing it this way.
Otherwise I'd endorse using tikz.
Are you sure you want to do it in LaTeX? Desktop publishing software might be more suited to your needs... Something like scribus might be easier than tikz in terms of learning curve, depending on what you want to do.
I'd like to add on to #midtiby's answer...
You can also specify the text position using a relative position, like so:
\usepackage{tikz}
...
\begin{tikzpicture}
\node[inner sep=0] (image) at (0,0) {\includegraphics[width=4cm]{imagefile.png}};
\node[above=0 of image] {Hello world};
\end{tikzpicture}
My code is simple enough, and importing eps images is something I've done before with other matlab-generated content, but for one reason or another I end up with blurred colors in my heatmap when I use epsfig or graphicx to import it into my document. In the picture below, the right is what shows up if I compile to DVI and open up the document in Yap, and the left is if I simply view the eps in GSView.

Here is my code. This example is using graphicx, but the idea is the same with epsfig.
\begin{figure}
\centering
\includegraphics[scale=0.5]{images/ngram3_model_raw.eps}
\caption{The perplexity when compared
against the HUB test set}
\end{figure}
Is there perhaps some option I am forgetting?
I had the same problem with DVI, but if I compiled to pdf the pictures were fine
What you see is bilinear interpolation. It is done by the viewer. Probably Matlab defines the plot contents as a pixmap (I guess you use imagesc?).
The solution is not straightforward. It may help to use a different processing chain (as WtFudgE pointed out) that will lead the data end up in a format where it is not interpolated anymore. You may also use a different viewer that does not interpolate and I would assume that a printer would also not interpolate. This can again be dependent of the application you print from.
Sorry that I don't have a solution for you; at least you now have some new words to search for in Google. ;)
In Latex how can you make the background image to occupy the whole sheet on every page except a certain stripe on the inner side of each page? I can't figure it out.
I have a background image I'd like to be seen in whole on each page after printing/binding.

There's some rather scary LaTeX hackery involving putting a picture environment under every page and using \includegraphics to put an image into that environment. You'll have to adjust the size of the image using the width option, and if you want even and odd pages you'll have to check the page number to know whether to shift the image right or left by changing \put(0,0) to \put(3,0) for example.
For page number testing try something on the order of
\ifodd\count0 ...stuff for odd-numbered pages ...
\else ... stuff for even-numbered pages ...
\fi
This isn't really a full answer but will be enough to get you started.
Honestly, I'd just add the white space in the image :)
Well, I was thinking of something like this.
Is this really so rare need to have? I myself need such a thing for the first time now but I don't feel it a so big oddity. It's strange for me that if you want a background to change over even and odd pages, just like normal text do, you need to feel betraying Latex logics. Or maybe I'm too fanatic of this challenge of mine and I want to feel the whole tex world change to fulfill my wishes. :)
Thank you for the answers!
