I think IDL includes the bounding box so that whatever
application you intend to include your EPS file in can
at least save the space for the graphic, even it it
can't render the PostScript itself. That is why, for
example, if you included your "renamed" file in
a Word document it would show up as a big rectangle
with an X though it and "IDL graphic" or some such
written at the top.

Most EPS files, though, also contain, in addition to
the PostScript part of the file, another part that
allows the graphic to be "previewed" in applications.
So, if you had created your PostScript file in IDL
with the ENCAPSULATED and PREVIEW keywords set
appropriately, and you include THAT file in your
Word document, you might see more than a big
rectangle with an X in it. If you had been living
a pious life, you might even see something that looked
like the graphic you intend to print.

However, when you send that Word file to a PS printer,
the graphic will use the PostScript part to render it,
not the low-level preview part.

Of course, IDL preview images suck, but I--like you--
have never been too bothered by that. They print correctly,
that's the main thing. :-)

Cheers,

David
