Right size for images to use in PP

[Rune Boa Nielsen]

I'm preparing a database with pictures, that are mostly
used in PP.
I made the pictures to be max 1024 pix wide or 768 px
high, and expected them to fit in a PP presentation (they
are 72 dpi).

But they are much larger than the screen, eventhough were
runnning 1024x768.
How come?
And what's the right size for pictures that should fit in
PP as a full screen picture?

 

[Rune Boa Nielsen]

PS: I know the can be resized - but it will be "novice"
users that will do this, and therefore I would prefer if
the pictures automatically fit

Rune,

I know of *no* way of getting the standard powerpoint to insert a picture
from file and have it fit the whole page.

IMHO - I believe it hazards a guess at how large to initially display the
image...based on pixels/dpi/ppi/and the current weather over chicago/minus
42 for good measure

But you are going about it the right way.....1024x768 is the way to go.

Notice I added the "standard powerpoint" in my original post?

From the holder of the FAQ.....Steve R

Regardless of how you get the pictures into PPT, you could download our free
PPTools Starter Set at http://get.pptools.com

The Remember Position and Place Exactly tools will let you size your
pictures repeatedly with a single click.

Thanks
Then I'll just let it rest there - and maybe explain the
users how to resize pictures!!

Hi Rune,

for a trade fair I needed a quite unusual slide size for projection on a
screen of 12.5x4.5m. I did the following: Using "File - Page Setup" I
resized my slides to 25x9cm (i.e. the same aspect ratio). Then I drew a
rectangle AutoShape filling the whole slide. With right mousclick and "Save
as image" I saved it as a PNG-file. I opened this in a Graphic Program and
found out the size in pixel and that it was saved with 150 dpi. My colleague
resized our photos according to these values. When I inserted them, it
worked without any resizing (which was important for the slide transitions
to fit exactly).

If you apply this method to a standard slide size (in the German version of
PowerPoint 2002 it is 25.4x19.05cm), you get an image size of 1504x1129pixel
with a resolution of 149.9 dpi. So format your pictures to 1500x1130pixel
and 150 dpi (to have smoother values) and it should work for a slide size of
10x7.5inch.

Kind regards,
Ute

You're on the right track.

Different versions of PowerPoint behave differently when you import images.
Which version are you using, and what format are you storing the images in?
What other formats are options?

What about giving the users a macro to bring in the image? It's simple to
size the image on import to whatever the current slide size is.

Back again. Ute's post gave me another idea.

Try setting the image dpi to:

1024 / SlideWidth

So for a slide set to 10" wide, that's 102dpi.

Save as JPG or TIF (both carry dpi/sizing info that PPT can read) but not
GIF/PNG (which don't).

This is tested with PowerPoint 2000. With other versions, your mileage will
almost certainly vary.

That works pretty close, Ute, except that 150 DPI is meaningless in the
world of PowerPoint. PowerPoint will throw away the extra pixels because it
is designed for displaying on monitors which don't have "DPI". For example,
my monitors are set to 1024 X 768. If I insert an image that is 1500 X 1130
pixels, 476 X 362 pixels get thrown away when displayed. So I prefer to
size to 1024 X 768 and keep the size of my presentations slightly smaller.

Better sit down. Seeing this from my fingers may shock you. ;-)

Ute's correct in this case; if you save to TIF or JPG, among others, you
can take an image that's sized correctly for the monitor (1024 pixels wide
for example) and save it at any DPI you like. PowerPoint uses that (or the
derived size in inches: Pixels/DPI = Inches) to size the picture initially
when you bring it in.

Changing the dpi setting has no effect on the image whatever IF you don't
let the image editing proggie re-sample. You can set the dpi to whatever
you like and force the image into PPT at whatever size you need, up to a
point. (or should that be "pixel"?)

The rules change from version to version of PPT. MS does its best to keep
us entertained and give us something to discuss when it's all verklempt.


For example,

Back again. Ute's post gave me another idea.

Try setting the image dpi to:

1024 / SlideWidth

So for a slide set to 10" wide, that's 102dpi.

Or change the page size to suit for 72dpi images:
14.22"x10.66" should work for 1024x768 images saved at 72dpi (subject to the
image format embedding dpi data).

I did a search on Google Groups and came up with this gem from 1999 (link
may wrap):
http://www.google.co.uk/[email protected]#link2

Save as JPG or TIF (both carry dpi/sizing info that PPT can read) but not
GIF/PNG (which don't).

....PNG varies - depending upon the software that saves it. Photoshop (pre
version 7) didin't embed dpi data in PNGs but the format is capable of it.

 

[Ute Simon]

Adam,

I tried the 10"/102dpi version, it works fine too.

But please be careful when quoting older newsgroup-messages: when the
message you found was posted, PPT 2002 was not invented (most of us will
have used PPT 95 or 97 then). And obviously Microsoft has changed its
internal picture handling technology since (see Steve's posting "The rules
change from version to version ...").

The reason that I prefer PNGs is, that their compression method is better
than JPG. A white picture background IS white, and not "white with some
greyish and yellowish dots" as in most JPGs and thus can be made transparent
with PowerPoints Transparency Wand, if necessary, or even can carry its own
transparency information in an alpha channel.

Kind regards,
Ute

Ayup. But since the idea is to create an image library for use by untrained
users, it's probably better in this case to adjust the images to PPT rather
than t'other way 'round.

Too funny! Can't we just get this information ... oh, I dunno ... like
tatooed on the back of every Office user's hands or something?

A perfect example of the English expression "coals to Newcastle"!

Oooops, that's where I got most of my knowledge about transparency (but
obviously my memory of names is bad) - excellent article, Adam!

Anyhow, I've learned a new English expression ;-) - thanks for that, Steve!

By 'eck...you aren't half as green as you are cabbage looking (that's a
compliment by the way...though it doesn't sound like one).
I was thinking the wrong way round..i.e. inexperienced users shouldn't have
to change the image dpi...

Which is ironic bearing in mind what a meagre coal mining industry we have
these days.

That wasn't my point...but even I can't remember what was my point...

But...for the record...at least in my experience...the 1024/page inches rule
works for every PowerPoint version since 97.
The NBs are:
In PowerPoint 97 the page doesn't quite fill the screen, so exact image
sizing is not possible.
In all versions the usefulness of this trick disappears if you move away
from Small Fonts. Large fonts seems to cause the image to be sized at 71%
upon import on my test machine, though resetting its size to 100% returns it
to fill the page.

I'm glad it was useful.

Does Google have a Geordie translator? ;-)

That they shouldn't. That's why this project has a smart user attached to
