Images resolution

[Guest]

I want to resize my images for PPT presentation

how many px/inch should I be working with?

 

[David M. Marcovitz]

Ignore pixels/inch. Instead you want to think of overall pixels and have
that match the screen on which you will be displaying the PowerPoint. One
of the most common screen sizes is 1024x768 so that is a common size for a
full-screen picture. Of course, if the picture is only supposed to take up
part of the screen, then something smaller might be in order.

Hello tmirelle

Screen resolution for images is 72ppi (pixel per inch - like dots per inch
for printed material). If you are resampling your image choose the final
size (1024 x 768 as David suggested) and set the resolution to 72ppi.
SuperPresentationMan also uses 96ppi because then you can zoom in a little
bit without compromising image quality. However, for the best results and
the smallest file size it's best to display your image at 100% size at
72ppi.

Have fun

Correct me if I am wrong, but I am fairly certain that if the final size
is set to 1024x768 it makes absolutely no difference if the image is
72ppi, 96ppi, or 1000ppi. If there are 1024 pixels of resolution on the
projector, and your picture is using all of them, the ppi is irrelevant.

Sorry, I wasn't clear in my response, if you resample your image and change
the size in units other than pixels then the resolution is important. If you
choose the size based on pixels, David is correct, you dont need to worry
about your resolution.

Thank you for clarifying that David.

thanks... I am also creating some custom art in fireworks...

keeps coming in to PPT blurry... I'll try 72px/in thanks

Hi tmirelle

There is an option in Fireworks for pixels/inch or pixels/cm which will make
a big difference to the resolution (choose 72 pixels/inch).

However, if it's your text that is blurry have a play with the Anti-Alias
settings in the text dialogue box.

Good luck

Correct me if I am wrong, but I am fairly certain that if the final size
is set to 1024x768 it makes absolutely no difference if the image is
72ppi, 96ppi, or 1000ppi.

To the image, no difference whatever. Depending on the file format you save it
to, the dpi setting may or may not be preserved; in formats where it is, PPT
may respect the consequent measurement in inches when it imports the image
(iow, 1000 pixels at 100dpi means 10"). A convenience in some cases, is all.

But again, the image is absolutely the same except for the four or eight bytes
where they stash the "Let's pretend that this picture is 10" wide" info.
