That method isnt always very successful especially when newer versions
of powerpoint are used to generate the slides.
For this particular powerpoint file OpenOffice renders some text on at
least one page unreadable.

In the case of html pages (at least with Linux or FreeBSD) converting to
pdf files can be done by first printing to a postscript file and then
opening the resultant postscript file with Ghostview and then printing
it to a pdf file.

There's also this (earlier?) similar HTML paper available  -
different coverage re quartz oscs etc. Might be an earlier version of
the ppt presentation.

Hi Bruce,

The difference you are seeing is because there is no equivalent font, on
your system, to the microsoft patented font specified in this Powerpoint
document.  OO.org makes a best guess as to what the document wanted, and
uses that for display.

Unfortunately, the best guess is about 5% larger in size.

This comes about because, Microsoft apparently didn't understand the
internationally standardized font sizes when they wrote their Office
suite.  The open source folks refuse to adapt to broken software as a
default condition.  I believe if you install the intentionally broken
Open source clone of the True Type fonts, you will see the presentation
as its author intended (+/- minor changes to stay legal).

Powerpoint has its own problems dealing with documents that were made
on differing Powerpoint versions, as does the rest of the MSOffice suite.

Using the term diopters on page 4-57 is potentially confusing.
Presumably he means the so called opthalmic (spectacle) industry
"diopter" tools were used to generate the curves.
The term diopter strictly means the reciprocal of the focal length
(measured in meters) of a lens.
The focal length of a thin lens depends on its refractive index and the
curvatures of its surfaces.
A spectacle industry 1 diopter tool will generate the convex surface of
a planoconvex lens with a power of 1 diopter (1m focal length) when the
refractive index of the material used is ~1.52.

Since the none of the refractive indices (1.54421, 1.55333 @ 600nm) of
crystalline quartz are equal to 1.52, labelling the curvatures in this
way is potentially misleading.

HOW TRUE your last sentence!!!  I've had to fight many battles with
presentations used in training classes that were written using whatever font.
Then when you try to present using a machine that doesn't have that particular
font installed, you get a HUGE mess!  We've even tried going to embedding fonts
in the presentations, but even that doesn't always work.
I just did some training for the Air Force, so I had to use one of their
computers, since it was part of a really nice classroom setup complete with rear
projection.  However, they had very few fonts on that machine, and it made some
of this slides, especially ones with formulas on them, total gibberish.  Talk
about throwing you off guard!  I'd review the material in my hotel room the
night before, but when I put the questionable slides up, it would totally
confuse me.  As a result, my student evaluations weren't so hot.  (one commenter
said "the instructor seemed like he was "winging it"").  I might as well have
been!

That's one advantage of using PDF in that kind of situation.  The "slide
show" presentation isn't quite as nice as with PowerPoint or OO, but
it's much more independent of the environment on the machine.

And, of course, OO has a very nice "Export to PDF" option available for
all its modules (write, draw, calc).

May be a dumb question but why don't you just export the slides to bitmap graphics or
to a PDF?  I rarely give presentations anymore but that's the approach I've always
taken, especially if I'm going to have to use other hardware.  A series of TIFFs or
JPGs and the free Irfanview which will run on a thumb drive or CD and you're set.

Hi John

Yeah, that's my method of choice for my own stuff.  Unfortunately, I don't have
that option when I'm doing it "professionally"!
Also, normally when I do it I can use my own, or at least a known to me PC.
This particular presentation was the "presentation from hell" though.
