[Tex/LaTex] Insert text inside a image in eps format

epsgraphicsMATLABtikz-pgf

UPDATE:I tried the solution with overpic and it works fine. But the problem is, sometimes, my experimental setup changes and I have to reproduce the eps file using different parameters from Matlab. This results in me again re-adjusting the co-ordinates to align the tex code corresponding to the different objects in the image(eps format). This is difficult when I have to do it often. Is there any solution for that?

QUES: I have an image of solid rectangle generated in eps format from Matlab. Let us say, there is no other way for me to generate the same (I have other complicated things inside this rectangle). I want to mark the co-ordinates of the corners of this rectangle. Thus, I want to insert some text of the form

$(\lambda_{min},\lambda_{max})$

inside the image. The inbuilt editor of Matlab is not satisfactory. Is there any option in LaTeX to do the same?

PSfrag is a LaTeX package that allows one to overlay Encapsulated PostScript ( EPS) figures with arbitrary LaTeX constructions. I know that it works for figure created with MATLAB but I forgot if there are any caveats. I very seldom use MATLAB to create pictures for my documents. I use PSfrag often with Xfig. It is included in most TeX distribution with exception of KerTeX.

For photos, screenshots and such bitmap graphics, you could use their native format (to preserve quality) if it's jpeg or png. Otherwise convert those pictures to png or at least to lossless jpg.

For drawings, plots and diagrams you better use a vector image format, because it can be scaled without quality loss. Possible vector formats are pdf and ps.

It also depends on which compiler you use: latex or pdflatex. The latter has some benefits like better justification because of microtypographic enhancements and it natively supports jpg, png and pdf, and you can use ps if converted to pdf.

My usage order with pdflatex is

pdf - for example output of other programs
ps - PSTricks or program output, then I use ps2pdf to go to 1.
png - screenshots, bitmap graphics (if necessary convert to png)
jpg - only if it's already the source format because jpg often uses lossy compression

Without pdflatex the question is not very interesting, latex supports only eps, conversion of bitmap images to eps is often not satisfying.

[Tex/LaTex] Rotate eps image without the whole page

the -dAutoRotatePages=/None works only on images which are rotated itself, the reason why it should work for the whole document. However you can also try:

\begin{figure}[hbt]
  \centering
  \special{ps: gsave -90 rotate }
  \includegraphics[width=1\textwidth]{simulink_model.eps}
  \special{ps: grestore }
  \caption{A Simulink Model}
\end{figure}
