Does anyone know if there is a way of exporting PPT images as greyscale
jpegs (or pure black & white) rather than colour, as per PPT printing?
Everything we try comes out in colour.

Thanks.

Hi Martin,

Try this:

Save your slide as JPG, then open it in Microsoft
Photo Editor.

Click on File, Properties and change the type to Grayscale
(8 bit). Save the grayscale file.

Takes two steps, but it gives you the results you want.

HTH,

Thanks, Glenna.

But how do I invoke the greyscale properties that I have so carefully set in
PPT? White background, black text, inverse greyscale graphs,
black-with-white-fill objects and so on?

I guess I should have mentioned that!

Martin

Which version of PPT are you using, Martin?

In PPT 2000 and 97, if you do the File/Save as/Image while you're in B/W
view, you'll get B/W images. However, you must do this from "normal" view,
not slide sorter view. Also, this won't work with JPG, PNG, or GIF. It will
work with TIF or WMF, though.

So I'd export as TIF and then use PhotoShop to batch process a conversion to
JPG.

If you're using PPT 2002, the B/W image save is broken, and you'll need to
use the technique Glenna mentioned.

Sorry I don't have a better answer for you. Maybe Steve's PPT Export will do
it, though? Steve?

Hey Martin,

You probably won't like this answer, but did you try
saving a BW version of your slideshow and using Format,
Slide Color Scheme, Custom and creating a "pure" grayscale
version of the slideshow? If you select the colors as all
variations of gray, it'll save that way as JPGs when you
export them. If you start with setting the color scheme
on the master slide, it'll save a lot of time.

We are building a script generator for a client - a sort of sophisticated
interchange between PPT Notes pages and WORD.

If we simply put a JPG into WORD and print it on a B&W printer, it prints as
a grey mush; so we want to find a way of using the excellent user-settable
capabilities of PPT greyscale as the basis for exporting the picture.

We don't mind a bit of programming, but we are unable to find any way to
capture this PPT greyscale image!

We would like to avoid using any other program, so batch conversion in
PhotoShop isn't going to help - even if it could do what PPT itself does
very well.

It seems absurd that such a very potent and successful part of PPT can't be
got at!

If you're using PPT 2000 or higher have you tried the
File, Send to, Microsoft Word Feature?

Yes - tried it - but it exports in colour.

Click on View, Black and White

Click on File, Send to, Microsoft Word and pick a format.

Comes out Grayscale on your Word document.

Not on mine! But I'll try again in the morning. Thanks for your interest.

Not in PPT 2002, it doesn't.

Check http://www.echosvoice.com/gotchas.htm Save as B/W and Send to Word.

Let PPT arf them out in color.
Let IrfanView batch slurp the color out and save as grayscale.

No, unfortunately not.

For just a few images, I'd print to a b/w PS driver and make PDFs, then
screen shoot those at relatively high zoom levels to grab the B/W images.
Or if you have Acrobat, use it to export PDF pages to TIFF or whoever.

Hmm. Or print to B/W PS and import the PS into Corel Draw and export from
there.

Or PPT --> PS -->GhostScript/GhostView --> ImagesOfWhateverFlavor

Last week it was Sysiphus, this week it's Tantalus. ;-)

Yep. What makes it worse is that it used to work the way you'd want/expect
it to. Then they fixed it.

Echo....this is exactly what I get with a quick test I've just done.

Both tests.....
Slide View
View Black & White
Save as TIF, JPG, PNG

Powerpoint 97=black and white images (as you would expect)
PowerPoint XP=color images (not good!)

What's interesting is that the black and white images from powerpoint 97 are
not true "grayscale"....but color files which only use shades of gray. e.g.
they can be converted to true grayscale images in an image editor


Cheers

The trouble with that is you still end up with the same sort of
undifferentiated greyscale that you get when you simply print a coloured
chart on a greyscale printer. I want to use the user-defined greyscale
properties so that I get quality output, not mush! And the quality of the
image would be much improved too, at a fraction of the file size.

But thanks everyone for trying.

Martin

Martin,
You could create a clone presentation which mimics the view and then exports
the JPEGs. I wrote one to mimic PPT2000's b/w view to send the output to
Word.

One other option: try out our Palette demo at http://get.pptools.com

No help for images and other suchlike goodies, nor for OLE et al. But for
PPT-native stuff, it's worth a look.

In addition to Steve and Shyam's suggestions, I think Glenna's earlier
one about applying a b/w template may be a fairly straightforward
solution. Just depends on the presentation, I guess.
