Exporting EMF graphics from PP

We are experiencing problems exporting EMF graphics from PowerPoint.
Our current process is to export as WMF, however we have received
requests to use EMF instead. What we are finding is that a graphic that
is exported as WMF is 624 x 354  Pixels while the same graphic exported
as EMF is 3900 x 2212  Pixels. In many cases we are not actually
exporting the graphics, but rather copy and pasting them into Word
documents where the graphics are extracted and converted to GIF for
html. The increase in size makes them unusable and so we are presently
limiting our users to WMF. Any ideas?

Thanks,

If you use a right-click and Save as Picture instead of pasting into Word,
does that do any better?

What kind of graphics are you doing this with? Are they just autoshapes?

For the most part they are pie charts, bar graphs etc.

If you right click and save you get the same result.

In truth, neither is true.  EMF and WMF graphics don't have any size in pixels.
They're by and large "vector" graphics, meaning that nearly everything in them
is composed of mathematically described shapes, not rows of dots.

What program are you importing these WMF/EMFs into?  I'm guessing that it
treats them differently (converts them into dots and differnt default dpi
settings).

With that many steps involved, it's hard to say where to point the finger of
blame.  If the goal is to make a GIF, why not do that directly from PowerPoint?

We're taking them out of PP and pasting or inserting them into Word.
The Word file is used to create XML and the graphics are also extracted
from the Word doc. Depending on our outputs we either use the original
(for PDF) or convert them to GIF (html).

Over the years we've found that the best results come from pasting as
WMF. I am aware that these are vector based formats, but do not know
why the graphic appears to be sized properly in an Office App, but is
much larger when viewed with a graphics viewer or by just dragging into
IE.

Marc,
Steve Rindsberg is the man to discuss this with in great detail. You
already have my email address from Kathleen. Drop me a note and Steve
and I can set up a conference call to discuss in more detail.

WMFs/EMFs?  I wouldn't worry too much about what they look like in viewers/IE; you
won't be using them on your web pages anyhow, I wouldn't think.  WMFs may or may
not have sizing instructions in the file format; as exported from PowerPoint, they
do, but may not in other cases.
