Including POSTSCRIPT pictures into a LaTeX file
Postscript files can easily be included and scaled in LaTeX documents.
For encapsulated postscript files (.eps, .epsi), the easiest method
uses the epsf style, and is described below.
On the other hand, if your postscript file is not encapsulated, and
does not contain a bounding box, you have two choices:
1) you may convert it to an .eps file using the ps2epsi converter in
the gnu locker:
athena% add gnu
athena% ps2epsi file.ps
will create file.epsi
2) you may use the PSbox macros in the consult locker, and follow the
second set of directions below.
----------------------------- USING EPSF --------------------------
1. Add the line
\usepackage{epsf}
to the beginning of your document, after the \documentclass line.
3. When you want to include the .eps file, use the
\epsfbox{filename.eps} command. You can scale the postscript file
by using either \epsfxsize=width or \epsfysize=height to specify a
width or height; the other dimension will be scaled accordingly.
You must include the \epsfxsize or \epsfysize command before the
\epsfbox; otherwise you'll be scaling the *next* figure.
4. If you need to center the file and are getting error messages ,
enclose it in an \mbox:
\begin{center}
\mbox{\epsfbox{filename.eps}}
\end{center}
---------------------------- USING PSBOX ---------------------------
1. First, you need to copy two "style files" into the same directory as your
latex files. To do this, change into the same directory as your latex
files, and then type:
attach consult
cp /mit/consult/lib/tex/macros/ps*.sty .
Alternately, you can add the path /mit/consult/lib/tex/macros/
to your TEXINPUTS; a line in your .environment file such as
setenv TEXINPUTS .:/mit/sipb/share/tex/macros:/mit/consult/lib/tex/macros/:
will include the LaTeX styles in both the consult and sipb lockers,
in addition to the default styles (don't forget the ":" at the
end!). Note that sipb and consult must be attached in order for
these paths to work.
2. Under Latex2e (the default), add the following line after your
\documentclass line:
\usepackage{psbox}
3. If possible, generate the postscript file such that the picture is flush
against the lower-left-hand corner. (For example, if idraw is being used,
group the entire picture and move it to the lower-left-hand corner of the
page. If it is a raw postscript file, add an appropriate translate
command, if you know how.) When you do this, the left most 1/4" of the
document may not be printed, since although (0,0) is at the lower-left hand
corner of the page, on some printers the left most 1/4" part of the page
isn't part of the image area. Don't worry about it.
4. Print out the postscript file. There are two reasons for doing this. The
first is to make sure that there aren't any errors in the postscript. The
second reason is to get the dimensions of the picture and where it is
located on the page. Measure the height and the width of the graphic.
Also, if the graphic is not located in the lower-left-hand corner, measure
the (x,y) distance from the lower-left-hand corder of the page to
lower-left-hand corner of the graphic IN INCHES.
NOTE: If your postscript file was created in Xfig, make sure that it
does not use "fills", as these do not come out correctly when used
with dvips on the Athena printers (they come out as solid colors as
opposed to shades or cross-hatched patterns).
5. a) If the postscript file has the image in the lower-left-hand corner
of the page, it's really easy. At the point where you want the picture
to be included, just use the following command:
\PSbox{/mit/username/filename.PS}{1.7in}{0.25in}
Where the first argument is the filename of the postscript file, the
second is the width of the graphic, and the third argument is the height
of the graphic. The dimensions can be specified in any format that
LaTeX accepts. So, for example, a dimension such as "4cm" will also
work.
This "PSbox" can be centered, included in a figure, or anything else you
want!
b) If you were unfortunate enough as to be unable to get the graphic in the
lower-left-hand corner, all is not lost. However, you will need to do a
bit more work. Take the distance from the left-hand side of the page
(which you measured in inches, right?) and multiply by -72. Call this
number the "$hoffset". Take the distance form the bottom of the page to
the bottom of the graphic (also measured inches), multiply it by -72,
and call it the "$voffset". Then the PSbox command should be modified
to be:
\PSbox{/mit/username/filename hoffset=$hoffset voffset=$voffset}{$width}{$length}
For example, to include a file which is 4 inches high and 5 inches wide,
which is located 3 inches from the bottom of the page and 2 inches from
the left side of the page, the PSbox would be:
\PSbox{/mit/username/filename.PS hoffset=-144 voffset=-216}{5in}{4in}
6. You can also shrink and scale your postscript figures (read RELEASE NOTE
below!) For example, if you wanted to include your figure shrunk by half
in each direction, you would used:
\PSbox{/mit/username/filename.PS hscale=50 vscale=50}{2.5in}{2in}
(with the dimensions being the size of the figure once it has been scaled
to half size in each direction). Scale values are in percent. Note that
it's possible to shrink your figure in one direction and not the other; in
most cases, though, you want to scale it equally both horizontally and
vertically.
RELEASE NOTE: these scale values are for use with dvips ONLY, and will
not work with dvi2ps (on machines running Release 7.6 or older). For
dvi2ps, hscale and vscale values should be specified in decimal fractions
(.5 instead of 50).
