    Hi all,

    A friend of mine called me other day with a question regarding
    presentation styles. He wanted to know how to include
    a "fade" effect on the whole slide except at one or two regions.
    In particular, he has this horrific math equation where
    he want to fade out most of it leaving out only
    the relevant part. From what I could understand, this would be
    similar to the fade effect at the OSX "System Preferences" window.
    In other words, he does not want to clear the whole slide but
    only fade what is not "important".

    Does anyone has a suggestion/idea how to make this effect as
    smooth as possible ?

    At first I thought about preparing a normal slide and then
    overlapping a second one on top of it but this is far from
    having a smooth transition.

    Thanks !

    You would probably need to split the maths equation into two parts (e.g. compile it in LaTeX (or whatever) separately) and then fade out the relevant part.

    :D :D :D
    You're asking the PowerPoint/Keynote all time lord/geek here :p

    Yes, you could do it. You would have to make an object out of two separate halves. Imagine a square with a hole in the middle where you want the highlighted section to show through, then split this exactly in two down the middle. Those are the two halves you will have to draw in Keynote. You would then group them together and set them to maybe 50 % transparency. Then simply use the fade in/fade out effect afterwards. :)

    Thanks, Eraserhead.

    It sounds a good way to do this but he made clear that
    there was a problem when dimming out the "non relevant" parts at
    the same time.

    Is it possible to fade multiple boxes at once ? (I am far from being an
    expert so bear with me, please)

    Ok, grouping the pieces is the key !
    I will talk to him...maybe he can still work out something before next Monday.

    Thank you all.
