PowerPoint question

[David Kowalsky]

hi all,
i am trying to blow up a picture in a slide.
I need to have it blown up when I hover over the picture. The solution existent in Office 2003 is select the picture, select Slide Show -> Custom Animation. In the Custom Animation pane, select Add Effect -> More Effects -> Basic -> Grow/Shrink and you may choose % of growth which would be almost OK (since it plays the effect on click and not on hover), however when the picture is blown up, the loss in resolution makes the picture useless ...

Anybody has any idea how can i solve this problem?
Thanks,
kowalsky

You would probably need to put in a larger image and/or higher resolution
than the one you currently have.

Is it possible to use hyperlinks (mouse hover) to go to a slide with the
image already "blown up" using a higher resolution or larger copy of the
image and then link back to the previous slide. I have used this method to
"enlarge" particular areas of a picture. Started with a 5 megapixel image.
Created a lower resolution copy of the image and put it on the menu slide.
Placed transparent box over the image for the area that I wanted to enlarge.
Hyperlinked the box with mouseover to go to the higher resolution cropped
image. I then include a box on that slide to go back to the menu page so
that the user can go to another area of the picture.

The problem with the method you are using is that it is a smaller picture
that is "running out of bits" to create the larger image thereby making the
program fill in the vacant areas. A common problem when trying to enlarge a
smaller image.

Thanks for your answer, I guess I'll have to settle for something close to what you say ... actually I already started (hover directly on the small pic and go to the next slide with the pic already blown up) - it's a little bit confusing since I have 3 pics and I want to toggle among them ...
Anyway, the loosing bits part - that I don't agree with, though. I have that same pic (439 K, by the way) enlarged by dragging the sides and it looks just fine; what I want to say is that anytime I play with the size in design mode on the slide there is no loss in quality - only when I use the Grow selection on the animation effect, that's when it really goes down the tubes. I mean, I tried with even higher reolutions and it still turned them to garbage ... well, thanks again,

When I use a 5 megapixel picture, resized on the screen to a smaller image
and then use the grow/shrink feature I too get a very distorted (pixilated)
image when it grows to full screen. While I am not totally sure, I believe
that PPT basically takes a "snapshot" of the smaller image and uses that
snapshot to enlarge instead of resizing like you would do with the resize
handles during image insertion.

The only way that I see out of that problem is like what I advocated in my
first post. Hope you find another solution and good luck.
