The Windows version of PowerPoint now provides the ability to adjust
image resolution. This looks like a very nice feature - is it available in
the current Mac version of PowerPoint?

Hi Gene,

Yes, this has been a feature on Macintosh PowerPoint for several years.
The Mac version has many additional formatting features that are not
avaiilable on Windows such as special effects, soft shadows and
transparency.

But (Think Different) it's not the same feature. ;-)

I think the op means the Ccompress Image feature in Windows PPT from 2002 on.
It can compress individual images within a presentation or the whole pressie's
worth.

PPT Mac users can set the DPI PPT uses when it exports image files but I can't
find any trace of the compress image feature in PPT X.

The fill transparency slider in the shape formatting dialog box?
In Windows PPT since 2002; simple 50% on/off transparency in PPT since 97 (and
it's actually supported 0-100% transparency since then if you prodded it with
VBA.)

Sneaky, these 'softies.

Hi Steve,

In my response to Gene I was thinking about the following Mac PowerPoint
resolution setting: if you use the Format Picture dialog (Control-click
on a picture) on the Size tab in the Scale section there is a
"Resolution" setting. This setting adjusts the selected picture for the
best size based upon the anticipated screen resolution that will be used
when the presentation is played.

But there are other resolution controls.

In PowerPoint's preferences there are "Advanced Resolution Controls" to
adjust the size of the graphics that are used when saving a presentation
as a series of pictures. There is also an option to compress graphics files.

In the Save As Web Page window you can click the Options button to
control the size of the picture that will be saved based upon the
aniticpated screen resolution of the user of the web page.

If you control-click a picture and choose to save the picture as a file
you will get a 72dpi picture no matter what. There is a feature request
in Microsoft's database that the save as picture feature be able to be
controlled by the user.

In Mac PowerPoint there is an over-all transparency control adjustable
in 1% increments, and in Fill Effects you can adjust the transparency of
multiple colors over a range, for example from 20% to 55%
transparancy for the particular color combination, and then you can use
the overall transparency control on top of that.

That's in Windows PPT as well. It's a resolution setting of a sort, but
doesn't change the image rez; instead it changes the size of the image on the
slide in an attempt to produce a one-image-pixel = one-screen-pixel display.

Yup. That's the Mac resolution setting I was referring to. Windows PPT is
missing that and the ability to choose compression or none for the exported
images. You have to resort to candlefeathers and chickenwax to set rez on
exported files under Windows. Or buy one of our addins. said:

That's a new feature in 2004, then? I don't see it in X or 2001. OTOH,
there's a way to do it in VBA - it's a hidden method, but the .Shape object has
an .Export method you can use to specify the output resolution. That's
available on Mac PPT X and probably any version that does the newer-style HTML
exports.

Yup. Same thing in Mac PPT X and Windows PPT 2002 (XP) and onward.

Big difference, though: It actually prints from Mac PPT. From Windows, forget
it. <g>

But back to the OP ... given the subject (Compress Image ...) and that it
refers to the Windows version, it almost has to mean a feature that isn't
present in PPT X, that I can find at least: if there's an image on the slide,
you can select it, go to the formatting dialog and see a "Compress" option on
the "Picture" tab. That lets you compress the image in place, as it were, and
will also let you delete portions of the image that have been cropped.
