Graphics, Figures & Tables ⇒ Add arrows to Matlab generated EPS?

[stinkinrich88]

Hello,

I made a plot using Matlab and exported it using laprint.m so that psfrag will replace the matlab text with LaTeX text.

I now need to add some arrows to the plot, but I can't figure out how to.

I used Inkscape to add the arrows, but when I save it (still as an esp) psfrag no longer replaces the text. I think this is because Inkscape uses Cario to export the esp, but I'm not sure.

How can I do this? Perhaps I can save the arrows in a separate esp file and overlay it?

Thanks,

Rich

Hi,

perhaps the overpic package could be useful for you.

Just for the record. The file format you mean is called EPS (Encapsulated PostScript), This might not appear important for you. But the search function would fail if somebody searches for EPS related problems. Therefore the title of the thread has been conformed.

Hi, sorry about the EPS error!

Thanks for recommending Overpic. It seems to do what I require, however, I cannot work out how to match the size/positions. I thought it would be simple as both images have the same papersize and are perfectly positioned for eachother, but when I use the following code, the arrow overlay is far too big:

Code: Select all

\begin{overpic}[width=0.6\columnwidth]{RandomWaypoint.eps}%
	\put(0,0){\includegraphics[width=0.6\columnwidth]{Arrows.eps}}%
\end{overpic}

Thanks

If it is possible for you to attach both images to your next post, then we could do some tests and make a suggestion.

Certainly. It would not let me upload eps files to this site, so I have hosted them here:

http://users.cs.cf.ac.uk/R.P.Coombs/bucket/Arrows.eps
http://users.cs.cf.ac.uk/R.P.Coombs/buc ... ypoint.eps

I have also attached the file used to insert the images (and use psfrag), so to display the images you should only need this code:

Code: Select all

\begin{figure}
	\begin{center}
		\import{RandomWaypoint.tex}
	\end{center}
\end{figure}

And psfrag, grapihicsx, overpic in the preamble.

Thanks!

You can put them into a ZIP or RAR archive. I will contact the administrator and ask him to extend the list of allowed file types.

[stinkinrich88]

Ok, thanks. I've attached a zip archive containing all three files.

The bounding box for Arrows.eps is 50 50 193 216. Change the last part of RandomWaypoint.tex to

Code: Select all

% Figure:
\begin{overpic}{RandomWaypoint.eps}%
	\put(50,50){\includegraphics{Arrows.eps}}%
\end{overpic}
\end{psfrags}%

In your .tex document, use the abs option for the overpic package and use the \scalebox command to scale the figure, as the following example suggests:

Code: Select all

\documentclass{report}
\usepackage{graphicx,xcolor,psfrag}
\usepackage[abs]{overpic}

\begin{document}
\begin{figure}[!ht]
 \centering
 \scalebox{.6}{\input{RandomWaypoint.tex}}
\end{figure}
\end{document}

Oh that's perfect! Thanks very much
