Image Size Problems in Powerpoint

[David Taylor]

I'm new to PP and I've got this problem in that when I
put an image in a PP slide it shows, in slide show view
on the monitor, as being a different size, in pixels,
than it really is. i.e. the image is 1280px wide, which
is the same as my screen resolution, but the image
presents itself as being about half the screen size
despite the fact that the PP image formatting says its at
100%. I've been to one Web help site and that says that
dpi makes no difference. So, I've done one slide with a
300dpi version of the image and another with a 72 dpi
version. The 72dpi one(at 1280px wide) presents itself
actually larger than the screen size at 100% formatting.
So I'm more confused than ever. I basically want to put
images in PP slides that show themselves on a monitor or
projector at the pixel dimensions of the image. Any help
very appreciated.

DT,

PowerPoint will always 'anti-alias/smooth' any bitmap image when it shows it as an on-screen show.

I don't believe you can ever get 1:1 pixel for pixel in powerpoint and have it look nice.

Basically if you want to show your presentation at 1280px wide....and you want your pictures/images at the best quality
for 1280px wide...then make your images 1280px wide (forget the dpi). When you insert them into powerpoint (powerpoint
takes a guess at how big to initially display the image IMHO)...just scale them (using the corner handles) to fill the
screen. Powerpoint will take care of the rest.

In addition to TAJ's comments, you could use a little VBA routine to
size the image to full screen.
Assuming US full screen it'd be something like
..top = 0
..left = 0
..width =720
..height = 540

These are Point measures and not pixel measures. Pixels only have to
do with resolution. Points, in PPT, have to do with position.
I ain't touchin' DPI lest the DPI DR(indsberg)AGON show up.
