I am using dvi2ps (from MIT?) to convert LaTeX output to postscript. I am
running on a network of Sun 3's and 4's (and one crummy 386i) under SunOS
4.0.1. The manual page for dvi2ps mentions support for the TeX \special
command which should allow the inclusion of encapsulated Postscript. I am
not having any luck at all getting figures to appear where I want (if I
can get them to appear at all).
Would someone please e-mail directly to me ways to include the following
Postscript code as a figure (with a caption) within a LaTeX document
scaled arbitrarily?

I have tried things like the following with no success...
--- begin LaTeX code--------
\begin{figure}
\special{psfile=foo.ps hscale=.5 vscale=.5}
\caption{test caption}
\label{figure_x}
\end{figure}
--- end LaTeX code--------Dunstan_Vavasour@uunet.uu.net (04/25/89)
I looked into this in some detail a while back when trying to include f2ps
output in a LaTeX document. The fundamental point is that the TeX \special
function doesn't leave any room at all. It just reads in the Postscript
file and splats it exactly where the \special command is.
Now, I don't have any knowledge of Postscript at all, but as far as I
understand it, TeX treats the point where the \special command is written
as the origin of the Postscript file (the term use is "the user's (0,0)
point"). This means the point where a paragraph of text would start is
(typically) the bottom left corner of the Postscript image.
The sort of construct you want is
--- begin LaTeX code--------
\begin{figure}[tb]
\vspace*{5.7in}
\special{psfile=fig1.ps}
\caption{Schematic of the static model}
\end{figure}
Start of next paragraph....
--- end LaTeX code--------
The blank lines are important - if you don't put them in things come out
in funny places (a TeXpert will be able to explain why).
I've never tried the hscale, vscale options to \special, but I have never
got the offset options to work, so the scaling ones should be treated with
some scepticism.
If you wish to preview the results of this jiggery pokery before printing
it, I suggest you use the RalPage Postscript previewer, which is freely
available (though not in the Public Domain).

I have noticed from your posting that you have tried to embedd a
PostScript graphic data within your LaTex document as a figure. I have
only succeeded in embedding a PostScript input within a LaTex file not in
a figure environment. I used the \vskip command before it so that LaTeX
will know that it has to skip the picture, then I put the \special
command, which included an additional hoffset parameter to position the
picture correctly in the page, and then continued. I found out that the
picture is best put in a page of her own (surrounded by \eject from both
sides).
I only resorted to this solution because I needed to place a copy of the
SUN screen in the file. Otherwise, for figures drawn by FIG, it is best
to transfer the FIG file to LaTeX with fig2latex, and plant this
information in a figure environment in your LaTeX file.
BTW, you can add the figure caption in your PostScript file instead of
using a figure environment. Alas, it will not appear in your table of
figures.
