Side size and resolution, please help !

Hello Everyone,

I'm new to PowerPoint and having trouble understanding resolution, image and
slide sizes.
I have read all the tutorials on the web but still can't figure out the
following:

I am designing a presentation for on screen display 1024 X 768 resolution
(pixels) that will be projected.
I am designing each slide's graphics in Fireworks PNG format - each slide
will be one large image in PNG format.

Now I don't understand the logic behind this - If I make the canvas size in
Fireworks 1024 X 768 pixels as suggested in all the tutorials, and I then
import this image (1024 X 768) into PowerPoint, it overlaps the slide size
by quite a bit, hence I have to drag and resize the image to fit the EXACT
slide size.

If I go to page setup in PowerPoint, the EXACT slide size default for on
screen display is set to 25.4cm (W) X 19.05cm (H) which when converted into
pixels equals 720 X 540 pixels (not 1024 X 768 ??).

Does this mean that I should in actual fact be setting my Fireworks canvas
size to 25.4cm X 19.05cm (720 X 540 pixels)?? That would mean the image fits
perfectly into the slide layout in PowerPoint, but since my on screen
display it set to 1024 X 768 it's not the correct size ... I'm lost here !

Would appreciate any advice please. Thanks in advance.

How are you converting into 720x540 - please show your working out.

When you import an image into powerpoint, it's normal for the image to be
too big or too small. Just re-size it to fill the slide in powerpoint.

Hello TAJ

Firstly thanks for the reply!

To answer your question - Working on 72 DPI - If I create a new canvas in
Fireworks or PhotoShop (doesn't really matter which app) using the
dimensions of the default silde layout 25.4cm (W) X 19.05cm (H), it
automatically converts the canvas to 720 X 540 pixels - So effectively
25.4cm X 19.05cm equals 720 X 540 pixels at 72 DPI (direct conversion from
cm to pixels)

To get even more technical, 1024 X 768 pixels when converted directly to
centimteres is actually 36.1244cm X 27.0933cm. (at 72 DPI)

This is confusing me because everyone is saying IGNORE DPI, size your images
to 1024 X 768 pixels (same as my screen and projector), but in actual fact
720 X 540 pixels is the correct size your image should be if you want it to
precisely fit the default slide size without having to crop or make
smaller...? Does this make sense?

BUT - if you increase the DPI to say 150 DPI and size your canvas to 1024 X
768 pixels, it converts to 17cm X 13cm..

DPI seems to play a bigger role here than people are saying, or I'm still
completely lost :)

You're making it all far too difficult.

If your computer's set to 1024 x 768 when you play the show and your images are
set to fill the slide in PPT, then your images will be projected at a size of
1024 x 768 pixels

That's all you need to worry about.

Make your images that size. The size that PPT chooses to insert them at
initially depends on a whole bunch of factors that are in the end irrelevant.

Make the image fill the slide. Your 1024x768 image will project at its natural
size, nothing gets distorted, nobody gets hurt.
