Images don't fit entire slide + Timing slides

[Seraya]

If my screen settings on my computer are set to 1024 x 768 and I have
an image that is just a little bit under 1000 pixels wide, doesn't
that mean the image should just about fill the entire slide area in
Powerpoint? I inserted a whole heap of images into a P/P document and
they all only filled about a third of the slide area. Before scanning
the images, I measured them and only scanned them at a resolution that
would result in just enough pixels to fit the entire slide area - in
my case I scanned at about 178 ppi. I can't understand why this is
happening. Can someone point me in the right direction?

I'm also experiencing another problem whereby I need the slides in the
presentation to automatically advance over a 4 minute and 45 second
period. Someone explained how to do this earlier, but after working
out how many seconds to enter before each slide progresses and also
adding a dissolve transition, I'm finding that the timing is out by
over a minute. Is it the transition that is making it longer than it's
supposed to be?

Any help would be appreciated

Not necessarily. It does mean that the image is scanned at adequate
resolution to fill the slide, or nearly so, and look fine as a screenshow.
Meaning that even if PPT doesn't import the image at the size you know it
should (and you're the smart one here, don't forget), you can still size it
up to what you know is the correct size.

Each version of PPT seems to have its own quirks as to the way it sizes
imported images, and different image formats can give different results even
within a given version of PPT. So once again, the best advice is to trust
your instincts - you're doing EXACTLY the right thing - and override what
PPT thinks about it. It's sometimes right, but in this case, wrong.

As to exact timing ... alas, Powerpoint simply doesn't do that.

Regarding the timing question, I looked back on previous posts and
TAJ, it was you who gave me the following instructions on how to do
the timing:

A quick sum....

4 minutes = 60 seconds x 4
= 240 seconds

40 slides divided by 240 seconds = 6 seconds per slide.

After you have "inserted > picture > from file" in powerpoint for each
picture on each slide. You then need to "view > Slide sorter".


To arrange the timing
================
Edit > Select All (to select all 40 slides)
Then
Slideshow menu >Slide Transition
Untick "advance on mouse click"
Tick "automatically after x seconds"
Enter 6 seconds on the "seconds" box.
Apply a transition effect...(e.g. wipe right) if you think it's
appropriate
Click "apply to all"

So, when Steve says you can't have the slide advance over a certain
period, and you're agreeing, I'm getting a bit confused since you
showed me how to do it in the first place. Do you mean that even
though you enter a certain amount of seconds in the "seconds" box, it
is not possible to have the show play for a certain amount of time,
accurately?

Just to make things a bit clearer: The slide show will be playing,
while an orchestra is playing music over the 4 minute and 45 second
period and I was asked to make it so that the slide show would play
over this time and end as the orchestra ends.

Maybe they're asking too much????

here's my 2 cent:

178 ppi is an odd setting, and the dpi setting is not really relevant
anyway these are used for print screen ruling, what matters here is
the number of pixels you need in your end document : here 1024 on
screen.

So if you scan a 1/1 inch document at 178 dpi this will result in a
178px by 178px image, if your source document is 10/10inch than the
resulting scan will be 1780px by 1780 px. What you should really look
for in your scanner settings is the resulting pixels in the target
image (regardless of dpi/ppi). Going back to that 10" document if you
target it at 1000 px only you will get the same "image information" at
50dpi or 500dpi the only difference will be it's printing resolution:
with the same 1000 pixels at 50 dpi you get an image of 20/20 inches
and at 500dpi that same image will be 2/2inches with the same 1000
pixels (try it in photoshop to get the mechanics image size>change
resolution>uncheck resample).

The second issue here (and it's a bit confusing) is when you import in
powerpoint. The PC standard monitor resolution is 96 dpi (an image at
96 dpi will display 1/1 on a pc) while on the mac it is 72dpi. So one
might expect that if you have an image of 1024/768px@72dpi it will
import 1/1 in powerpoint x ... wrong, powerpoint on the mac has
inherited an odd ~102dpi rule and so the 72 dpi image displays larger
at the 72 dpi mac standard. that same image resaved @102dpi in
photoshop (remember no resampling) will now import 1/1 in pptx.

conclusion:
what really matters is the number of pixels not the dpi. the dpi will
only affect the diplayed size of the image when you import it, so
don't be afraid to resize in ppt it will not affect the final display
as long as your image pixels match (or better are greater than-) your
screen display.
resave your images @102dpi (no resampling) in photoshop and they will
import the way you expected.

hope that makes it clearer for you now,

Mickael,

You're right it's the pixels that count and not the dpi

Have you seen this tutorial on the same subject?

TAJ, it was you who gave me the following instructions on how to do
the timing:

The original instructions I gave on timing are still valid.
e.g. If you have 6 slides that are to last 60 seconds, then 10 seconds per
slide is still valid.

If you have any slide/page transitions...these +add+ to the total time
If you have any object transtions (e.g. bullets wiping on)...these also
+add+ to the total time

If you have no slide or object transitions...then 6 slides at 10 seconds
will finish in about 1 minute.

However....but....caveat....
Powerpoint is notoriously bad at being consistent!

The 1st time you run a slideshow it may take x + y seconds to complete
The 2nd time you run a slideshow it may take x + z seconds to complete
The 3rd time you run a slideshow it's more likely to be the same as x + z
(i.e. more consistent)

Regarding the image sizing question, I wrote an add-in that will
automatically size pictures to fit the entire powerpoint screen. I
realize this is blatant advertising, but it seems like this add-in might
be appropriate for you. It does *not* do a bulk import of lots of
pictures. You have to insert them one at a time.

The add-in is here:
http://www.agentjim.com/MVP/PowerPoint/ppt.html

It is based upon sample code available here:
http://www.rdpslides.com/pptfaq/FAQ00329.htm

Getting the pictures to size properly regardless of original shape and
orientation is trickier than it might seem to be at first glance.
