3.3    Converting PS files to EPS
Single-page PostScript files without any improper commands can be 
converted to
eps by using one of the following methods for adding a BoundingBox line. 
Since
these methods do not check for illegal PostScript operators, they do not
produce usable EPS files unless the PS files are free of forbidden 
operators.
    1. The most convenient option is to use the ps2epsi utility 
distributed with
       Ghostscript (see Section 6.1 on Page 17), which reads the 
PostScript file, cal-
       culates the BoundingBox parameters, and creates an eps file 
(complete with
       a BoundingBox) which contains the PostScript graphics.
       The resulting file eps file is in epsi format, which means it 
contains an Inter-
       change (low-resolution bitmapped) preview at the beginning of the 
file. Since
       this preview is ascii-encoded, it does not cause the Section 4.1 
bufsize errors.
       However, this epsi preview increases the file size.
    2. Another method of having ghostscript calculate the BoundingBox 
parameters
       is to use the epstool utility, available for Unix, dos, Windows, 
and OS/2 from
                   http://www.cs.wisc.edu/~ghost/gsview/epstool.htm
       For example, the command
               epstool --copy --bbox file1.eps file2.eps
       analyzes the contents of file1.eps to determine the correct 
BoundingBox and
       then copies the contents of file1.eps with the calculated 
BoundingBox into
       file2.eps.
       The epstool utility can also be used to add tiff, wmf, epsi 
bitmap previews
       to an eps file, or extract bitmap previews from an eps file.
    3. Alternatively, the BoundingBox parameters can be calculated and 
manually
       inserted in the PostScript file's BoundingBox line or specified 
in the graphics-
       insertion command (e.g., the \includegraphics command's bb 
option). There
       are several ways to calculate the BoundingBox parameters
        (a) Use Ghostview/GSview to display the PostScript graphic. As 
the pointer
             is moved around the graphic, the pointer's coordinates 
(with respect to
             the lower-left corner of the page) are displayed. To 
determine the Bound-
             ingBox parameters, record the pointer coordinates at the 
lower-left corner
             of the graphic and the upper-right corner of the graphic.
        (b) Print out a copy of the PostScript graphics and measure the 
horizontal
             and vertical distances (in inches) from the lower-left 
corner of the paper
             to the lower-left corner of the graphics. Multiply these 
measurements by
             72 to get the BoundingBox's lower-left coordinates. 
Likewise, measure the
             distances from the lower-left corner of the paper to the 
upper-right corner
             of the graphics to get the BoundingBox's upper-right 
coordinates.
         (c) The bbfig script uses a PostScript printer to calculate the 
BoundingBox.
             bbfig adds some PostScript commands to the beginning of the 
PostScript
             file and sends it to the printer. At the printer, the added 
PostScript com-
             mands calculate the BoundingBox of the original PostScript 
file, printing
             the BoundingBox coordinates superimposed on the PostScript 
graphic.
             The bbfig script is available from
                                        CTAN/support/bbfig/
